[PYTHON] Environment construction with anyenv + pyenv (migrate from pyenv only (Mac))

What to write

How to change from pyenv-only environment to anyenv + pyenv environment (Uninstall pyenv, install anyenv + pyenv) Nothing new (for myself)

pyenv→anyenv+pyenv In conclusion, remove pyenv and install anyenv, install pyenv with anyenv and recreate the required environment According to here, it was written that a problem would occur if you simply moved the folder, so I decided to delete it and recreate it. did.

Check and delete what you installed with pyenv

% pyenv versions
%pyenv uninstall What to remove

Then uninstall pyenv

% brew uninstall pyenv

I think there is a description of the following 3 lines in .zprofile, so delete or comment out (commented out as below)

#export PYENV_ROOT="$HOME/.pyenv"
#export PATH="$PYENV_ROOT/bin:$PATH"
#eval "$(pyenv init -)" 

Also, there is a hidden folder called .pyenv in / User / username /, but I don't need it anymore, so delete it. (Let's clean up the problem even if it remains)

Install anyenv

% brew install anyenv

Add the following to .zprofile

% echo 'export PATH="$HOME/.anyenv/bin:$PATH"' >> ~/.zprofile
% echo 'eval "$(anyenv init -)"' >> ~/.zprofile

When you restart the terminal, you will be told as follows

% source ~/.zprofile    
ANYENV_DEFINITION_ROOT(/Users/username/.config/anyenv/anyenv-install) doesn't exist. You can initialize it by:
> anyenv install --init

follow orders.

% anyenv install --init
Manifest directory doesn't exist: /Users/username/.config/anyenv/anyenv-install
