Solution 1

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 -)"

Solution 2

Try this: into the terminal,

write: nano ~/.bashrc
add in the end:

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

Exit and save
into the terminal write: source ~/.bashrc

And it's all, this worked for me.

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?

That gets me Requirement already satisfied: setuptools in /Users/user/.pyenv/versions/3.6.5/envs/QGIS-virtualenv-3.6.5‌/lib/python3.6/site-‌packages Requirement already satisfied: pip in /Users/user/.pyenv/versions/3.6.5/envs/QGIS-virtualenv-3.6.5‌/lib/python3.6/site-‌packages

How do I add something to .bashrc. What is the shell on mac?

†he QGIS software comes in a .pkg. Now that I'm in my virtual environment, (my-virtualenv) bash-3.2$, how do I open the package just in the environment?

How do I add something to .bashrc? vim ~/.bashrc. Or echo 'eval "$(pyenv init -)"' > ~/.bashrc What is the shell on mac? I see bash-3.2 in your question, so I'm sure the shell is bash. QGIS software comes in a .pkg. … how do I open the package just in the environment? No idea what is that pkg but it's certainly not a Python thing.

I think perhaps we may be missing a step in your actions here. You're telling me that executing pyenv activate QGIS-virtualenv-3.6.5 immediately gives you Requirement already satisfied without you taking any other action after typing that? Is that what you mean to say?

The pkg is a software called QGIS. Can I install software just to the virtual environment? I set up the environment because the software requires python 3.6

I ALSO had to add eval "$(pyenv init --path)" to get this working. So 3 .zshrc additions.
