Installing specific package versions with Pip

I am a bit new to pip install and virtualenv in general.

I have setup an virtualenv on my server as well as on my local dev environment.

On the server the package django_modeltranslation-0.4.0_beta2 works perfectly fine.

However on my local machine django_modeltranslation-0.5.0-alpha doesn't seem to work well at all.

I usually simply install it in virtual-env like this:

$ source bin/active
(env)$ pip install django_modeltranslation

This gets the latest version though, which now for the first time causes issues working with latest version.

So I have uninstalled the version 5 alpha like this:

(env)$ pip uninstall django_modeltranslation

But now I don't know how I could get the working version 0.4.0 Beta again. I tried this but it couldn't find it:

(env)$ pip install django_modeltranslation-0.4.0_beta2
Downloading/unpacking django-modeltranslation-0.4.0-beta2
  Could not find any downloads that satisfy the requirement django-modeltranslation-0.4.0-beta2
No distributions at all found for django-modeltranslation-0.4.0-beta2

I think there must be a way, since that is the whole point of using virtual env.

  • @Kave: I realize that a recent 'just hack at it until it works' session included `#version` where it happened to work because of other reasons. Removed that variant altogether. – Martijn Pieters Dec 17 '12 at 15:27
