Hi Raghav, I am totally hooked on to your tutorials. I want to finish one by one all because you make everything so simple yet interesting. The Node.js framework has not yet been worked with, and I looked through all your video titles and neither specifies where I can learn how to set up node in the environmental variables, If you could share a link, I would be ever so grateful.

hi Raghav, I am getting an error after running my Test command in VS code. Though I have installed NVM on my local machine

[@RaghavPal]

If you're encountering the error message "'node' is not recognized as an internal or external command, operable program or batch file" after running a test command in Visual Studio Code (VS Code) and you've installed NVM (Node Version Manager) on your local machine, here are some steps you can take to resolve this issue: 1. Set the Default Node Version Using NVM: - Open your terminal (not the VS Code terminal) and run the following command to set the default Node.js version: ``` nvm alias default 7.8.0 ``` - This command sets the default Node.js version to 7.8.0. - Now, when you run `node -v` in VS Code, it should return the correct version (7.8.0). 2. Restart VS Code: - After setting the default alias, it's necessary to restart VS Code for it to pick up the changes. 3. Verify the Installation: - Make sure that NVM was installed successfully. You can run `nvm` in your terminal to verify if it outputs information about NVM. - If you still encounter the error, try closing your terminal, opening a new one, and running the command again. 4. Check Your Shell Profile: - Ensure that your shell profile (e.g., `.bashrc`, `.zshrc`, or `.profile`) includes the necessary NVM initialization. - If not, add the following line to your shell profile: ``` export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads NVM ``` - Restart your terminal or run `source ~/.bashrc` (or the appropriate file for your shell) to apply the changes. 5. Verify Node Installation: - Run `node -v` in your terminal to ensure that Node.js is installed and accessible globally. - If not, you may need to install Node.js separately using NVM. Remember to replace `7.8.0` with the desired Node.js version you want to use

WHich extension is required for getting the basic code for HTML by Just using "!"..

[@RaghavPal]

Hi Shanawaz, generally the basic support for html is included with VS Code (using latest version) . Just make sure your file has .html extension. Check this - code.visualstudio.com/docs/languages/html IF you do not get it, check these extensions - code.visualstudio.com/docs/languages/html#_html-extensions

[@rash1977]

Hello Raghav. What if Visual Studio code displays "'groovy' is not recognized as an internal or external command, operable program or batch file.

[@RaghavPal]

Rashmi The error "'groovy' is not recognized as an internal or external command, operable program or batch file" typically occurs when your system cannot find the Groovy executable in your system's PATH environment variable Here are some steps to help you resolve this issue in Visual Studio Code (VS Code): 1. Check if you have Groovy installed: Make sure you have Groovy installed on your system. You can download the latest version of Groovy from the official website: groovy.apache.org/download.html 2. Verify the Groovy installation: Open a new Command Prompt or Terminal window and type groovy -version. If Groovy is installed correctly, you should see the version number displayed. 3. Update the PATH environment variable: Add the Groovy executable directory to your system's PATH environment variable. This will allow your system to find the Groovy executable. For Windows: Right-click on "Computer" or "This PC" and select "Properties". Click on "Advanced system settings" on the left side. Click on "Environment Variables". Under "System Variables", scroll down and find the "Path" variable, then click "Edit". Click "New" and add the path to the Groovy executable (e.g., C:\Program Files\Groovy\bin). Click "OK" to close all the windows. For macOS/Linux: Open your shell configuration file (e.g., ~/.bashrc or ~/.zshrc) in a text editor. Add the following line to the end of the file: export PATH=$PATH:/path/to/groovy/bin (replace /path/to/groovy/bin with the actual path to the Groovy executable directory). Save the file and restart your terminal. 4. Restart VS Code: Close and reopen VS Code to ensure that the changes take effect. 5. Verify the Groovy extension in VS Code: Open VS Code and check if the Groovy extension is installed and enabled. You can do this by: Opening the Extensions panel by clicking the Extensions icon in the left sidebar or pressing Ctrl + Shift + X (Windows/Linux) or Cmd + Shift + X (macOS) Searching for "Groovy" in the Extensions marketplace. Installing or enabling the Groovy extension if it's not already installed. After following these steps, you should be able to use Groovy in VS Code without encountering the "'groovy' is not recognized" error -

can you help me out, "got this error: 'node' is not recognized as an internal or external command, operable program or batch file." when run hello.js

[@RaghavPal]

Hi Robert, The error message "'node' is not recognized as an internal or external command, operable program or batch file" typically means that Node.js is not installed on your system or the system's PATH environment variable is not configured to include the Node.js installation directory. To resolve this issue, you need to install Node.js on your system and add its installation directory to the PATH environment variable. Here are the steps you can follow: Download and install Node.js from the official Node.js website (nodejs.org/en/download/). Make sure to select the appropriate version for your system. Once Node.js is installed, open a new terminal or command prompt window and type the following command to check if Node.js is installed properly: node -v This should print the version of Node.js that you have installed. If the node command is still not recognized, you may need to add the Node.js installation directory to your system's PATH environment variable. On Windows, you can do this by following these steps: a. Open the Start menu and search for "Environment Variables". b. Click on "Edit the system environment variables". c. Click on the "Environment Variables" button. d. Under "System Variables", find the "Path" variable and click "Edit". e. Click "New" and add the path to the Node.js installation directory. The default installation directory is "C:\Program Files odejs". f. Click "OK" on all windows to save the changes. After adding the Node.js installation directory to your PATH, open a new terminal or command prompt window and try running your hello.js script again: node hello.js This should run your script without any errors.
