As a developer, encountering the “zsh: command not found: pip” error can be frustrating, especially when you need to manage Python packages. This error typically occurs when the pip command is not installed or not accessible in your current environment. In this guide, we’ll walk through the steps to resolve this issue and ensure pip is available in your Zsh shell.

Why Does This Error Occur?

The “zsh: command not found: pip” error happens when the pip executable is not present in your system’s PATH variable or when pip is not installed at all. This can occur if:

  1. You recently switched to the Zsh shell.
  2. Python was installed without including the pip package manager.
  3. The pip installation path is not correctly added to your PATH variable.

Step-by-Step Solution

Step 1: Verify pip Installation

First, check if pip is installed on your system by running:

1
pip3 --version

If you see the version number, pip is installed, and you just need to add it to your PATH. If not, proceed to the next step.

Step 2: Install pip

If pip is not installed, you can install it using the get-pip.py script. Follow these steps:

  1. Download the get-pip.py script from the official Python website:

    1
    curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

  2. Run the script using Python:

    1
    sudo python3 get-pip.py

This command will install pip on your system.

Step 3: Update Your PATH Variable

After installing pip, you need to ensure that the pip executable is accessible in your shell. Add the following line to your ~/.zshrc file:

1
export PATH=$PATH:/usr/local/bin

Then, reload your Zsh configuration:

1
source ~/.zshrc

This step ensures that the directory containing pip is included in your PATH.

Step 4: Verify pip Functionality

To ensure pip is working correctly, try installing a Python package:

1
pip install requests

If the installation is successful, you have resolved the “zsh: command not found: pip” error.

Additional Tips

  1. Using Virtual Environments: It’s recommended to use Python’s virtual environments to manage dependencies. You can create a virtual environment using:

    1
    2
    python3 -m venv myenv
    source myenv/bin/activate

    This approach isolates dependencies and avoids conflicts.

  2. Check Python Version: Ensure you are using the correct version of Python. Sometimes, systems may default to an older version. You can specify the version explicitly by using python3 -m pip.

  3. Update pip: If you encounter issues, ensure you have the latest version of pip by running:

    1
    python3 -m ensurepip --upgrade

Conclusion

The “zsh: command not found: pip” error is common but easily resolved by verifying pip installation, updating your PATH variable, and ensuring your environment is correctly configured. By following these steps, you can quickly fix the issue and continue managing your Python packages seamlessly.
