How to create a virtual environment when using homebrew + pyenv-virtualenv. Since it uses homebrew, it is for MacOS.

There are already many similar materials, but I have created my own memos.

Installation and pyenv settings

If you want to install pyenv-virtualenv and its wrapper, you can easily install it by using brew as follows.

% brew install pyenv-virtualenv
% brew install pyenv-virtualenvwrapper

If you are using homebrew-file, do as follows.

% brew file brew install pyenv-virtualenv
% brew file brew install pyenv-virtualenvwrapper

The following cautions will be displayed during installation, so set them later.

To enable shims and autocompletion add to your profile:
if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi

To use Homebrew's directories rather than ~/.pyenv add to your profile:
export PYENV_ROOT=/usr/local/var/pyenv

Set the environment.

% vi .bash_profile

I will add this content.

if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi

Enable the .bash_profile setting.

% source .bash_profile

Introduce Python using pyenv

Install python using pyenv. Here, I installed Python 3.3.6 as an example.

% pyenv install 3.3.6
Downloading Python-3.3.6.tgz...
-> https://yyuu.github.io/pythons/0a58ad1f1def4ecc90b18b0c410a3a0e1a48cf7692c75d1f83d0af080e5d2034
Installing Python-3.3.6...
(The following is omitted)

%

If PYENV_ROOT is not set, it will be installed under ~ / .pyenv / shims /.

Creating a virtual environment

Since I installed python3.3.6 earlier, I will use this to create a virtual environment with the name "sandbox336".

% pyenv virtualenv 3.3.6 sandbox336

Tips

List of things that can be installed with pyenv

Check what can be installed with pyenv as follows.

How to install django

If pip uses ~ / .. pyenv / shims / pip, install it with the pip command.

% which pip 
→ pip~/.pyenv/shims/Looking at pip
% pip install django

How to delete the environment

You can uninstall it as you installed it with pyenv.

% pyenv uninstall sandbox336
% pyenv uninstall 3.3.6
