Why Does Pip Install Packages to the System Instead of My Anaconda Environment?

Utilizing Pip to Install Packages in Anaconda Environments

Installing packages into Anaconda environments using pip is a convenient method for isolating packages within specific environments. However, users may encounter difficulties when attempting this process.

Issue: Despite activating a fresh Anaconda environment, pip installation attempts seem to retrieve packages from the system-wide location instead of the activated environment.

Solution:

1. Create and Activate the Environment:

   • Create an empty environment using conda create -n shrink_venv.
   • Activate the environment using source activate shrink_venv.

2. Install Pip in the Environment:

   • Run conda install pip to install pip within the activated environment.

3. Locate the Virtual Environment:

   • Identify the actual venv folder under Anaconda's directory (e.g., /anaconda/envs/shrink_venv/).

4. Install Packages Using Pip:

   • Install packages using the following commands either within the venv directory using /anaconda/envs/shrink_venv/bin/pip install package_name or simply using pip install package_name.

By following these steps, packages can be successfully installed using pip within the activated Anaconda environment.

Note:

To prevent interference from the system's PYTHONPATH, consider running unset PYTHONPATH before installing packages within the Anaconda environment.
