Installation

We strongly recommend using a tool like pipx to install this tool. This will isolate the dependencies and ensure they don't conflict with other tools.

$ pipx install evg-module-manager

Debugging installation issues

A common issue that arises during installation is pipx failing to install emm and printing out the following error:

$ pipx install evg-module-manager
Fatal error from pip prevented installation. Full pip output in file:
    /home/ubuntu/.local/pipx/logs/cmd_2022-03-31_13.24.42_pip_errors.log
 
Some possibly relevant errors from pip install:
    ERROR: Could not find a version that satisfies the requirement evg-module-manager (from versions: none)
    ERROR: No matching distribution found for evg-module-manager
 
Error installing evg-module-manager.

This error indicates that pipx could not find a version of emm that was built to support the version of Python installed on your machine. Make sure to check that your version of Python matches the requirements called out in the Dependencies section. You can check the version of Python that is on your computer by running

$ python --version

If you are running into the issue above but are sure that the correct version of Python is installed on your computer, you can explicitly specify a path to the correct Python version during installation.

$ which python3.9
/usr/bin/python3.9
$ pipx install evg-module-manager --python /usr/bin/python3.9
