Troubleshooting the pipx Not Recognized Error in Python Brownie Installation

Are you trying to install Brownie using pipx in Visual Studio Code but facing an error message stating that the term 'pipx' is not recognized? You're not alone. This common issue can be frustrating, but understanding how to fix it will help you get back to developing without a hitch. In this guide, we'll break down the problem and provide a clear solution to get you set up with Brownie.

Understanding the Problem

After following the installation instructions from Brownie's official website, you encounter this error message after typing pipx install eth-brownie in the terminal:

This message indicates that your system cannot locate the pipx command, which typically means there's an issue with your system's environment variable settings, specifically in the PATH variable.

Step-by-Step Solution

To resolve this issue, follow the steps outlined below to ensure that your environment variables are correctly configured:

1. Reviewing the Installation Steps

First, make sure you have correctly executed the following commands in your terminal before proceeding with pipx install:

The first command installs pipx, a tool to help you install and manage Python packages in isolated environments.

The second command should automatically update your system's PATH, adding the pipx installation path.

2. Check Your Environment Variables

Despite successfully running the commands, the issue can still persist due to how the ensurepath command modifies your PATH. It might add your pipx installation path in lowercase, while your system requires a capitalized version.

How to Check PATH Variables:

Windows:

Right-click on 'This PC' or 'My Computer' on your desktop or in File Explorer.

Select 'Properties,' then 'Advanced system settings.'

Click on 'Environment Variables.'

Under 'System variables', find and select 'Path', then click 'Edit'.

Mac/Linux:

Open the terminal.

Type echo $PATH and press Enter to view your current PATH settings.

3. Fixing the Directory Paths

In the PATH setting allowing the use of pipx, look for entries related to Python and pipx. If you see them listed in all lowercase such as /user/<username>/.local/bin, consider editing those entries to match the correct case.

For example:

Change /user/<username>/.local/bin to /User/<Username>/.local/bin (adjust according to the OS you are using).

4. Restart Your Terminal

After adjusting the environment variables, restart your terminal (or Visual Studio Code) to ensure all changes are applied.

5. Verify the Installation

Run the command again to verify if pipx is now recognized:

If everything is set up correctly, you should now see that the command executes successfully and Brownie is installed.

Conclusion

Encountering errors when setting up a development environment can be discouraging, but with this structured approach, troubleshooting the pipx issue should be much simpler. By carefully managing your PATH settings and ensuring case sensitivity, you can confidently continue your Python programming journey with Brownie. Happy coding!
