Setting up a new computer, I had to revisit this video to debug my containerized Python development tools (Python3, pip3, pipenv, and pylint) . Hint: Do Not hard-code the VOLUME and WORKDIR into the container definition; pass them as arguments to Docker at run-time. This video is the most concise, practical video about pipenv that I have watched.

[@ugur.nurcan]

still is the best tutorials for pipenv after 3 years. thanks Brad

[@loganwright3423]

I'm really loving your Python stuff. Between React, Node, and Python, you do a great job of preparing developers for the employable stacks of today. Keep the Python coming. Love it.

[@MarcMcRae]

After a bit of tinkering about this morning, your video helped clear a few things. Badly needed pipenv commands. Thanks Brad. Great share!

[@jgttech]

I'm a Java and JavaScript guy so this made a LOT of sense. Great video. Honestly, I am focusing more on JavaScript and Python nowadays. They seem to have a lot of innovation going on. That and Rust. I am learning Rust for WebAssembly.

[@CODERSNEVERQUIT]

Favourite notification ❤

[@khalilsarabey]

I was just reading about it this morning :)

[@moswilam91]

HEY BRAD, as one of your big fans, I urge you to HIRE somebody to answer questions in the Q&A section of your paid courses in udemy and other sites, you are a great instructor and I like your way, but I get very very frustrated when I have a question and i get no response whatsoever, I understand you are doing a lot of things and probably don't have time to follow up with each question, but at least hire somebody to do that. thanks !

[@Ronium22]

mo swilam Google should be able to answer quite literally any question you have.

[@moswilam91]

@@Ronium22 yeah google should be able to answer any question I have as much as I can get any knowledge I want by reading books and references, the point of taking a course is to acquire a specific knowledge in as little time as possible, I am sure you know how complicated and time-consuming it could get to explain a certain question in stackoverflow as an example, that in case I didn't find a direct and fast answer in google, which I always try to do, that's why I say it'd be much faster to have somebody to respond to a question if its on a certain topic in the course without the need to explain and reproduce a ton of code which could take hours just to come up with an easy way to illustrate it, I enjoy listening and learning from brads courses, but I have the right to express an opinion since I am paying for the service I am getting. and it's just a recommendation at the end.

[@riipandi]

I just read about pipenv couple hours ago, and now this video released. Great. All good things of PHP Composer, Nodejs NPM/Yarn, and Maven came with this tool. By the way, instead using python3/pip3 or pythonVERSION, you can set your default Python version.

[@Beachcasts]

You do a nice job explaining what your doing, thank you. I didn't realize Python development had this capability.

[@Theoadu1]

Brad, thanks for this gift.

[@FordExplorer-rm6ew]

These high production quality videos exist for a reason. To rope people into certain things or give them a perspective that the big companies want them to have. And, people who code are going to bend the knee easier to propaganda because of the thought patterns of the environments they are in typically all lean one way. This cycle has been observable since around 2014 Don't get me wrong free Tuts are a good thing. But it's always more of a grift than a gift. Grift grift grift

If pipenv shell is using 2.7 by default, you can do pipenv shell --python your.python.version like pipenv shell --python 3.8

Can we use the different python version in pipenv, like as you might know tensorflow doesn't work with python 3.7 you need to have python 3.6 to run and test tensorflow, although im using docker and docker image ofr tensorflow/tensorflow. but i wanna know is it possible with pipenv?

[@moswilam91]

one more thing, don't promise that you will update a course or add more topics to it unless you're sure that you will. and it would be better if you provide a time frame to that, again this is from a big fan of yours. thanks and Merry Christmas

[@subStuff]

nice tutorial, but, wouldn't the utility of pipenv become highlighted if things are explained with more than one virtual environments and switching between them.

[@madusan1]

I do like "pipenv --rm" which deletes the virtual env files of the project you are in. Useful when you are cleaning up older project files not required any longer..

[@mostafashawki]

Very Useful, thanks Brad :)

[@emekaonah4583]

This video was very helpful Brad, thanks plenty. I'm experiencing a problem with my pipenv tho and I'll be glad if you find time to help out. Whever I run "pipenv install django" the pipfile is created in the expected folder, but the pipfile.lock file isn't created. It produces this error: Adding django to Pipfile's [packages]... Pipfile.lock not found, creating... Locking [dev-packages] dependencies...

[@alyfalshaw3107]

No pip file created of as today, "Creating PipFile for this project..." is skipped and cmd lists straight to "Launching subshell in virtual environment". Is there a reason / concern for this or another way to view this file? Thought maybe it was a hidden file but that was not the case, giving me the assumption it was never created.

[@infinikeys]

Thank you for the vid. Do we need to install Python3 first to be able to install pipenv? Can I just install pipenv with python2? Thanks :)

[@gioruffa]

Thanks for the great video! I have a small question: what should be committed to git? The pip lock or the pip file? (or both)

[@brazenbull36]

always commit the package manager .lock file, be it php/nodejs/python

[@ArielPontes]

If I install packages inside the shell using the regular "pip install", is there any way I can get the Pipfile updated to include those packages?

PipEnv - introduction to pipenv why we need that instead of virtualenv ? - pipenv automatically install and manage virtual environment and provide easy way to add and remove packages using pip file which is similar to package.json in node environment. We have cheatsheet of pipenv made by traversymedia gist.github.com/bradtraversy/c70a93d6536ed63786c434707b898d55 when I was installing pip3 at the first time it was working fine but whenever I have installed pipenv and then again trying that out in my project folder it was showing error like Traceback (most recent call last): File "/usr/bin/pip3", line 9, in from pip import main ImportError: cannot import name 'main' That simply means that I havenot installed pip3 properly and I had searched for it in stackoverflow and finally got solution first attempt: askubuntu.com/questions/1025793/running-pip3-importerror-cannot-import-name-main failed !!!!!!!!! second attempt: askubuntu.com/questions/969463/python3-pip3-install-broken-on-ubuntu?rq=1 what was the propblem then ?? I just forgot to use sudo to install pip3 packages LOL AFTER SOLUTION WHAT NEXT ?? LETS DIVE INTO THE CHEAT SHEET AGAIN …. Problem again :( I have tried the command : pipenv shell to activate the pipenv and got the error as not expected pipenv command not found :( let us search for it again in stack overflow… Attempt 1 : and eventually got the success on it .. link: stackoverflow.com/questions/46391721/pipenv-command-not-found what was the problem ?? They have told that I had issue again not installing pipenv golbally again :) that little shit of SUDO again………. Solutions are already in that link but DONT FORGET TO USE SUDO while installing pipenv :) I had already installed it so I have to manage the path and as solution recommended I had done it like PYTHON_BIN_PATH="$(python3 -m site --user-base)/bin" PATH="$PATH:$PYTHON_BIN_PATH" with these aforementioned commands. INSTALLED ? THEN WHAT ???????????? activate ?? command is : pipenv shell BEFORE DOING SO WE NEED TO GOTO OUR PROJECT folder other wise it will create pipfile in user directory CORRECT ME IF I AM WRONG .. NEW TO LINUX SYSTEM How does Pipfile looks like : [[source]] name = "pypi" url = "pypi.org/simple" verify_ssl = true [dev-packages] [packages] [requires] python_version = "3.6" OK …… THEN ?? command : pip3 freeze for what ? => to show the currently available environment on my machine result => blank :D I don't have any any projects and environment till now I will check this out again later…. Have you noticed that we dont have to do python3 -version now … python -version will show the current version of python and in my case its 3.6 we are in completely different environment with pipenv wanna check that out ??? command: python then user commands like import sys => import system file sys.executable =>showing executable path of python it will display the your python file path on your machine… quit ?? use quit() so get back to pipenv with pipenv shell command so for testing we are going to install very comman package with pipenv install command command: pipenv install camelcase wanna check Pipfile ?? it looks like [[source]] name = "pypi" url = "pypi.org/simple" verify_ssl = true [dev-packages] [packages] camelcase = "*" [requires] python_version = "3.6" Have you noticed new package there .. * mean the latest version.. OMG that have created .lock file as well WHAT IS LOCK FILE THEN.. ?? .lock file will have all the dependencies and all of other dependencies of that dependencies It will provide us the final build so that we can use same version of everything while deploying project. CHECKING ON PYTHON TERMINAL NOW … Python 3.6.7 (default, Oct 22 2018, 11:32:17) [GCC 8.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> from camelcase import CamelCase >>> c = CamelCase() >>> s = 'this is my string' >>> print(c.hump(s)) This is My String how to list the packages with terminal command : pipenv lock -r UNINSTALL PACKAGE command: pipenv uninstall camelcase DEV DEPENDENCIES ??? => packages only for your dev environment not for your production environment how to do that with pipenv ?? =>pipenv install nose -dev so our pipfile looks like [[source]] name = "pypi" url = "pypi.org/simple" verify_ssl = true [dev-packages] nose = "*" [packages] [requires] python_version = "3.6" HAVE you noticed that ?? OK THEN … HOW TO INSTALL PACKAGES FORM requirements.txt file ?? simple command : pipenv install -r ./requirements.txt not going to try it for now …………. why not lets install django with requirements.txt file pip just created a requirements.txt file on root with single line Django==2.1.5 and ran the command pipenv install -r ./requirements.txt now we have django installed in our virtual environment… so let’s CREATE DJANGO PROJECT command: django-admin startproject testproject WOW what the heck was that it just happened very fast :) lets run that project command : python manage.py runserver WAIT WAIT !!! you are writing this command in wrong path first go to your TEST PROJECT PATH command: cd testproject then run it… hope you are getting expected output :D CHECK SECURITY ISSUE WITH pipenv command: pipenv check ALL PASSED FOR NOW :D HOW TO UPDATE VERSION OF packages …….. ??? => just update the version you want to install of specific package and run : pipenv install just like npm install or yarn install right ?? DEPENDENCIES TREE command : pipenv graph => this will show the graph or tree version of your dependencies and their dependencies …. AT LAST HOW TO MAINTAIN DEPENDENCIES AND THEIR VERSION ON PROJECTION ?? IF you run the command pipenv install in the server and they have * for their version then that will install lastes version ot that dependency so that to manage that we can instead use .lock file to maintain the versioning as per the development. - ignoring pipfile and use lock file - pipenv lock (for making lock file ) - pipenv install -ignore-pipfile DO YOU KNOW WE CAN USE PIPENV OUTSIDE THE VIRTUAL ENVIRONMENT FILE ?? go back to your global scope : exit command : pipenv run python this will open python terminal in the version that is installed in pipenv environment.. ALL CREDIT GOES TO TRAVERSY MEDIA :D ……. SORRY FOR MY EULISH :D
