pym: Simple python interpreter manager

NOT MAINTAINED. And I aware of we should use python-build. I hope python-build will be separated from pyenv.

pyenv offers a lot of python versions. Especially it can install anaconda easily.

But some features make an our environment to complex. For example, It is unnecessary for PyCharm users that the features to bind python interpreter to specific directory by pyenv local and pyenv global commands. And pyenv-virtualenv is too difficult for me. I want a more simple interpreter management tool.

pym just offers following functions.

• Installing specified version's python interpreter to under /opt
• Create symlink to /usr/local/bin
• Create virtualenv using pyvenv or virtualenv.

Installation

Mac OSX

$ brew tap c-bata/pym
$ brew install pym

Even if you don't use homebrew, you are avairable by the same way with how to install on linux.

Linux

• Download release file or Copy and paste pym script.
• Set PATH and add permission to execute.

$ sudo wget <pym_script_url_on_github_release> -P <path_to_pym_script>
$ sudo chmod +x <path_to_pym_script>

Dependencies

ref https://docs.python.org/devguide/setup.html

Fedora, Red Hat Enterprise Linux and other yum based systems:

$ sudo yum install yum-utils
$ sudo yum-builddep python3

Debian, Ubuntu and other apt based systems:

$ sudo apt-get build-dep python3.4

Tutorial

1. Install python

Following command install specified python under /opt/.

$ sudo pym install 3.4.3
$ sudo pym install 3.5.0

2. Create symlink

$ pym link --list  # It is the same as `ls /opt/ | grep python`.
3.4.3
3.5.0
$ sudo pym link 3.4.3
$ sudo pym link 3.5.0

Preceding command created symbolic link under /usr/local/bin/.

$ which python3.4
/usr/local/bin/python3.4
$ which python3.5
/usr/local/bin/python3.5

3. Create the virtualenv

$ pym venv --list  # show avairable interpreter. It is the same as `ls /usr/local/bin/ | grep python`.
3.4
3.5
$ pym venv 3.5 sandbox

$ source sandbox/bin/activate
(sandbox) $ python --version
Python 3.5.0

🎉 Congratulations!

Environment variables

• $PYM_ROOT The path where the interpreters are installed to. (default: "/opt")

• $PYM_PATH The path where the scripts are symlinked to. (default: "/usr/local/bin")

• $PYM_TMP The folder to store temporary file. (default: "/tmp")
