You also have to name your own script something other than activate.bat to avoid recursion, which is why I chose the cmd extension (which is treated by Windows as a batch file in this context).

My preference (on Windows, but the same principle would apply on Linux) is to create a (version-controlled) activate.cmd file in the root of the project directory that sets the environemnt variable(s) and then calls conda's own activate.bat script.Įxample (a per-project pylint configuration): set ?%\env (I understand that this does not apply to all projects - sometimes the entire reason for using environment variables is to prevent that particular configuration getting stored in version control.) Generally you'd want to store only the environment.yml file in version control. The accepted answer ( conda/activate.d and conda/deactivate.d) works well enough, but it is inconvenient if you want the environment variables to be version controlled without putting the entire environment into version control too. conda is not available from the standard terminal by default. from an environment.yml file Use the terminal or an Anaconda Prompt for the.
