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.
# pyenv setup, can place last in file
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv init -)"
Restart shell and try again.
~ echo "$SHELL" ✔
/bin/zsh

~ pyenv local 2.7.18 ✔
~ python ✔

Good
Can now i use python2.7.18 in Jupyter notebook?
Thank You for helping me. so main mistake was the shell used by Manjaro Linux.
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.
tom@tom-VirtualBox:~$ pyenv install anaconda2-2019.10

No that will not work,need a new Jupyter kernel that use Python 2.
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.
pyenv uninstall anaconda2-2019.10
