Hi,
(sorry for cross-posting)
A few days ago I needed to check whether some Python code ran with Python 2.6.
What is the easiest way to install another Python version along side the
default Python version? My own computer is Debian Linux 64 bit, but a
platform-independent solution would be best.
Possible solutions that I am aware of
-make altinstall *). This is what I tried (see below), but not all modules
could be built. I gave up because I was in a hurry
-Pythonbrew. This project is dead
-Deadsnakes
-Anaconda
-Tox? I only know this is as a cross-version/implementation test runner
-Vagrant. This is what I eventually did, and this was very simple. I ran Ubuntu
10.0.4 LTS, which uses Python 2.6, and used Vagrant SSH to run and check my
code in Python 2.6 (and I replaced a dict comprehension with a list
comprehension, for example)
- ...
What is the recommended way? I don't expect/hope that I'd ever need something
lower than Python 2.5
I use pythonz: http://saghul.github.io/pythonz/ It lets me specify not
just the version I want, but the implementation I want: I can install
CPython 2.6.1, PyPy 2.0.2, and Jython 2.5.3 all the same way.
