Is there a python equivalent of Ruby's 'rvm'?

Question

Q: Do we have anything functionally equivalent in Python to the Ruby version manager \'rvm\'?

Answer 1

pyenv 1.2.15 can build and install Python for you

Maybe this was not possible in earlier version, but when I tested in 1.2.15 I noticed the pyenv install option which worked:

pyenv install 3.8.0

Therefore I feel that it is reasonable to call pyenv a replacement for RVM.

I have given a fully detailed example of its usage at: apt-get install for different python versions

Answer 2

Yes, it is virtualenv along with virtualenvwrapper.

update: you may install both at once with virtualenv burrito.

Update: the correct answer is now probably pyenv.

For scientific computing, the corresponding tool is anaconda.

Answer 3

Optionally, if you're using Macports you can use python_select. Install python_select with:

$ sudo port install python_select

Assuming python 2.6 and 2.5 have bee installed via Macports you can switch pythons like so:

$ sudo python_select python25
=> Selecting version "python25" for python
$ python --version
=> 2.5.5
$ sudo python_select python26
=> Selecting version "python26" for python
$ python --version
=> 2.6.6

Answer 4

Pythonbrew is no longer under development. The former maintainer suggests to use "PyEnv" instead (see below)".

pythonbrew has come! http://github.com/utahta/pythonbrew

pyenv: https://github.com/yyuu/pyenv

Answer 5

Following up on hytdsh's answer (nearly two years later)...

pythonz a fork of pythonbrew that adds support for Stackless, PyPy, and Jython.

If you like how rvm handles different interpreters, it may worth taking a look at pythonz. If you're strictly working with CPython, the difference is less significant.

Answer 6

I created pyenv which is a fork of Ruby's rbenv and modified for Python. Like pythonz, pyenv also supports Stackless, PyPy, and Jython.
