for people whose "python -V" is showing old version after pyenv shell NEW_PYTHON_VERSION, head over to search bar and type "Manage app execution aliases" and untoggle all the python related thing, check if the command works now in a new terminal, if not then you have to uninstall all the previous instances of python installed from control panel while having already done the first step above. It should solve the issue. Enjoy folks!! Nice video dude

Thank you!

ugh didnt work, i'll have to go uninstall

This tutorial rescued me twice. Years ago I managed to install specific python environment using this tutorial. Then I completely forgot what pyenv even is and could not understand why I have old python installed and active even if I removed every python from "add or removed programs".

How can i disable temporarily this and use the python installed on the system instead?

[@ericcrossley4059]

ok so what do I do if I get to pyenv shell, and when i do python -v i get a huge amount of text back - presumably because i have system python on windows that is 3.10 ... i'm trying to do all this so i can run a thing that needs python 3.8

[@Rachelcenter1]

i watched your Apple version of this tutorial and it worked great. now im trying this version (windows) and when I do the global command and then check the version its still stuck on python 3.12.4 and wont listen to my global command to make it 3.10.11

[@ChrisSaur]

I installed 3.10.6 with the "penv install 3.10.6" but every time i try to swap to it or set it as global it shows me that i am on 3.9.12 afterwards. Is there a way to tell what I did wrong? I want to use python 3.10.6 for Stable diffusion while using a newer version of python for the rest of my system. Is this even the correct way to achieve that? I am here because I tried to install 2 python versions on WIn 10 and while installing python 3.10.6 it just told me that there is already a python verison on my pc so i cant install another. :(

[@drygordspellweaver8761]

Hey, this actually broke my entire site packages repository. Pip can not access any of the already installed packages. Is there a way to fix this?

[@k0nze_builds]

Each Python version installed through pyenv has its own set of pip packages. This is due to fact, that there might be version conflicts when switching Python versions but keep the packages. Regardless of this I would recommend to create a virtual environment for every new Python project and refrain from install pip packages systemwide.

[@drygordspellweaver8761]

@@k0nze_builds After many hours of searching online and trying everything I could find, I was unable to get pyenv working on my system. Either I had a 'base' install of python in which case pyenv was not able to change local or shell versions. Or, I had no base installation of python but py.exe would not work and I could only open files using python command in CLI. Actually, pyenv can 'change versions' for a local or shell instance but it doesn't actually execute (like running sys.version_info) I might have to try conda because I just cannot get this to work.

[@k0nze_builds]

You should not use py.exe to run python code. Always use python.exe because py.exe is a windows thing and can lead to weird behavior (as you have seen yourself).

[@drygordspellweaver8761]

@@k0nze_builds the IDE's all use py.exe

[@k0nze_builds]

That is not true. Some might use it but definitely not all. Furthermore, a decent IDE lets you change the Python interpreter path.

[@LiamG-b6p]

Great video, this has helped me alot. This is something I have struggled with for a while. The only question I have is around installing python packages/modules in the virtual environment such as numpy, scikit, matplotlib etc. Would this be as simple as using pip while in the virtual environment? Are these installed packages persistent when the environment is deactivated and activated again? If not is there a way to have these as a present to be installed every time the venv is activated?

Is running the command-prompt as admin the same as using powershell? What happens if you already have multiple python versions already installed, before you've installed pyenv? I sometimes have to run a windows setup exe or a whl to install a specific python package.. (for example PyQt 5.4 can't be installed via pip), how would this work with pyenv/virtualenv? I'm actually only interested in building EXEs from 2 python versions.. Python 3.4.4 (32-bit for WinXP) and Python 3.11.1 (64-bit). Would it be easier in my case to just change the PATH whenever I want to switch between? What would pyenv/venv add?

[@InPersian]

I already have python 3.11 and did not work for me. In pyenv I see 3.9.6 but normally '> python -v' returns 3.11.0 by the way it was really good

Check with get-command maybe you have another version of python that is also in the PATH that is picked up instead

This is a great video. Is there an easy way though to use pyenv to switch to the systems python version?

[@k0nze_builds]

Thank you William! I'm glad you enjoyed the video. The default Python version of you system is usually determined by the order of paths in the PATH variable. When you run "python" on the command line the operating system will check the PATH variable if it can find a match. The first match it finds is the default version.

[@williamsavage5724]

@@k0nze_builds I guess the problem I'm having is that I have 3.7.0 installed on my system, but the pyenv 3.7.0 doesn't recognize my installed libraries i.e. pandas. When I run pip install pandas again it says requirement satisfied (by my system's python)

[@k0nze_builds]

It seems like the pip you run is not the pip coming from pyenv but from the system python installation.

Does this have any benefits/better features over just using virtualenv? Just curious.

pyenv allows you to seamlessly switch between Python versions and Python interpreters such as CPython, PyPy, or Stackless Python. A virtual environment is focused on containing packages for your projects to install different package versions for various projects.

To the best of my knowledge virtualenv is the somewhat of a predecessor of venv and virtualenv is the only way to create a virtual environment using Python 2. No worries, about your name ;) I do have a Russian first name and know how awkward things are at the moment. There is only a few people close to the Kremlin that are responsible for this situation.
