In this guide, we will discuss how to fix the Pip path in Ubuntu 20.04. If you’ve encountered a warning like this: “WARNING: The script virtualenv is installed in ‘/home/mark/.local/bin’ which is not on PATH”, you’re in the right place.
To fix the Pip path in Ubuntu 20.04, you have two solutions. The first is to log out of your Ubuntu account and log back in, which will automatically add the necessary directory to your PATH. The second solution is to manually add the directory to your PATH using a terminal command. Additionally, you can suppress the warning by using the –no-warn-script-location flag when installing packages with Pip.
Understanding the Problem
Before we dive into the solutions, let’s understand the problem. This warning is raised because the directory /home/mark/.local/bin where the virtualenv script is installed, is not included in the system’s PATH. The PATH is a list of directories that tells your system where to look for programs, so it can run them anywhere, regardless of the working directory.
Solution 1: Logging Out and Back In
The simplest solution is to log out of your Ubuntu account and log back in.
- Log out of your Ubuntu account.
- Log back in.
When you log back in, Ubuntu will re-evaluate your ~/.profile file. If the ~/.local/bin folder exists, Ubuntu will automatically add it to your PATH. After this, virtualenv should work as expected, and future runs of pip3 should not raise the warning anymore.
Solution 2: Manually Adding the Directory to PATH
If the first solution doesn’t work or if you prefer a more hands-on approach, you can manually add the directory to your PATH.
- Open a terminal.
- Run the following command:
echo "export PATH=\"/home/mark/.local/bin:\$PATH\"" >> ~/.bashrc && source ~/.bashrcThis command does two things:
echo "export PATH=\"/home/mark/.local/bin:\$PATH\"": This part of the command writes the stringexport PATH="/home/mark/.local/bin:$PATH"to the end of the~/.bashrcfile. This string is a command that adds the/home/mark/.local/bindirectory to your PATH.>> ~/.bashrc: This part of the command appends the output of theechocommand to the~/.bashrcfile.&& source ~/.bashrc: This part of the command runs thesourcecommand on the~/.bashrcfile. Thesourcecommand makes the changes take effect immediately, without needing to log out and back in.
After running this command, the terminal will remember the updated PATH, and virtualenv should work properly without raising the warning.
Suppressing the Warning
If you prefer to suppress the warning instead of adding the directory to PATH, you can use the --no-warn-script-location flag when installing packages with pip3. Here’s an example:
pip3 install PKG --no-warn-script-locationReplace “PKG” with the actual package name you want to install. The --no-warn-script-location flag tells pip3 not to raise a warning when the script of the package being installed is not on PATH.
Conclusion
In this guide, we’ve discussed how to fix the Pip path in Ubuntu 20.04. We’ve covered how to add the directory to PATH either by logging out and back in or manually using a terminal command. We’ve also covered how to suppress the warning if you prefer not to add the directory to PATH. Remember, the PATH is a crucial part of your system’s environment, so handle it with care. Happy coding!
To check your current PATH in Ubuntu 20.04, open a terminal and run the following command: echo $PATH. This will display the list of directories in your PATH.
Yes, you can add multiple directories to your PATH by separating them with a colon (":"). For example, to add two directories "/path1" and "/path2" to your PATH, you would use the following command: export PATH="/path1:/path2:$PATH".
To permanently add a directory to your PATH in Ubuntu 20.04, you can edit the ~/.bashrc file. Open a terminal and run the command nano ~/.bashrc to open the file in a text editor. Add the following line at the end of the file: export PATH="/path/to/directory:$PATH". Save the file and exit the text editor. Then run the command source ~/.bashrc to apply the changes.
After adding a directory to your PATH, you can verify if it has been added successfully by running the command echo $PATH in a terminal. The updated PATH should include the directory you added.
Yes, you can remove a directory from your PATH by editing the ~/.bashrc file. Open a terminal and run the command nano ~/.bashrc to open the file in a text editor. Locate the line that contains the directory you want to remove from the PATH and delete it. Save the file and exit the text editor. Then run the command source ~/.bashrc to apply the changes.
To view the contents of the ~/.bashrc file, open a terminal and run the command cat ~/.bashrc. This will display the contents of the file in the terminal.
No, you do not need to restart your computer after modifying the PATH. To apply the changes immediately, you can either log out and log back in or run the command source ~/.bashrc in the terminal.
The --no-warn-script-location flag in pip3 is used to suppress the warning that is raised when the script of a package being installed is not on the PATH. This flag tells pip3 not to display the warning message.
