pyuserenv 1.1.2

A Python library for managing user-installed package lists.

UserEnv: User Installed Modules Manager

Do you work on a system where python environments are pre-configured, and your only way to add custom modules is using pip install --user ? UserEnv allows you to keep multiple sets of user packages in a single python environment, as user environments.

A Concrete Example

Let's say you need to use both NumPy-1 and NumPy-2 in the same environment. First, create a userenv for NumPy-1:

$ userenv create numpy1 && userenv activate numpy1
User environment 'numpy1' created at /home/adorni/.userenv/envs/numpy1.
User environment 'numpy1' activated.

$ pip install --user numpy==1.26.4
...
Successfully installed numpy-1.26.4

Then, create a userenv for NumPy 2:

$ userenv create numpy2 && userenv activate numpy2
User environment 'numpy2' created at /home/adorni/.userenv/envs/numpy2.
User environment 'numpy2' activated.

$ pip install --user numpy==2.4.4
...
Successfully installed numpy-2.4.4

Et voilà ! You can now use both versions of numpy the same way you would use a normal venv:

$ userenv activate numpy1 && python -c "import numpy; print(numpy.__version__)"
User environment 'numpy1' activated.
1.26.4

$ userenv activate numpy2 && python -c "import numpy; print(numpy.__version__)"
User environment 'numpy2' activated.
2.4.4

Installation

$ pip install --user pyuserenv
$ userenv setup

Make sure to follow the setup instructions with the modifications to your shell configuration file (e.g., .bashrc, .zshrc), then reload your config

source ~/.bashrc # example for .bashrc

You're good to go !

$ userenv --help
