[SOLVED] How can I make a virtual environment work with pyenv?

Issue

I'm trying to use QGIS, which requires python 3.6.x.

I'm on mac on a system that already has python 2.7 and 3.7.

I tried

brew update
brew install pyenv
brew install pyenv-virtualenv
pyenv install 3.6.5

It installs just fine. Then, when I try to activate

pyenv activate my-virtualenv

I get this error

Failed to activate virtualenv.

Perhaps pyenv-virtualenv has not been loaded into your shell properly. Please restart current shell and try again.

I tried again with

exec $SHELL
pyenv activate my-virtualenv

And received the same error.

I executed this command in bash-3.2$ and regular terminal 

if which pyenv-virtualenv-init > /dev/null; then eval "$(pyenv virtualenv-init -)"; fi

And I'm still getting the same error. How can I get an environment running that uses python 3.6?


Solution

Initialize pyenv:

exec $SHELL
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
pyenv activate my-virtualenv

To save yourself some typing add this to your .bashrc:

eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
