autoenv executes even in subfolder

Question

I uses autoenv for automatic virtualenv activate. Python project's top folder has .env file with following contents

source venv/bin/activate

This command executed whenever cd to any sub folder of the project. Then throws

-bash: venv/bin/activate: No such file or directory

It failed because it is trying to execute activate relative to sub folder. Why it executes even in subfolder? How to resolve the issue?

Answer 1

Had this issue today. The current answer doesn't address the fact that the environment is activated every time you cd into a subfolder or back to the root folder. Solved it with the following .env script:

venv=venv
currentvenv=""

if [[ $VIRTUAL_ENV != "" ]]
then
  # Strip out the path and just leave the env name
  currentvenv="${VIRTUAL_ENV##*/}"
fi

if [[ "$currentvenv" != "$venv" ]]
then
  echo "Switching to environment: $venv"
  workon $venv
#else
#  echo "Already on environment $venv"
fi

Replace venv with the name of your environment. You can uncomment the else block to see that it doesn't try to activate the environment every time, given that the desired environment is already activated.

Note: If you're not using virtualenvwrapper then you should replace the workon command with whatever command you're using to activate your virtual environment. I do recommend using virtualenvwrapper though.
