Pyenv: activate.sh command not found

When opening a vscode terminal when the python extension is loaded, it tries to execute this:

source /Users/victor/.pyenv/shims/activate.sh

Which triggers this error:

pyenv: activate.sh command not found

The `activate.sh` command exists in these Python versions:
    2.7.4

And then bluntly closes the terminal. Is there an issue with my pyenv installation here?
