Hmm ok,look lilke Manjaro(i dont't use it) use zsh as default shell.
Quote:Manjaro seems to install both bash (login shell) and zsh (user preferred shell, e.g. when opening a console).
Then you need to add lines to zsh shell.
So vi ~/.zshrc or nano ~/.zshrc and add same line to this file and save.

Restart shell and try again.

Good pyenv finally works 👍
Can now eg install a Anaconda that use Python 2,this comes with Jupyter Notebook pre-installed.
Example look at pyenv install --list.

The Anaconda version you install is stand alone,and will not affect other stuff that installed.
Can just remove when don't need it anymore.
