How to get list of available versions for a package on PyPi

1 Dec 2015

For most part you always want to install the latest version, but there is time where you need to install old version.

For an example, we want to know available version for package named Flask

From PyPi website

Instead of https://pypi.python.org/pypi/Flask, go to https://pypi.python.org/simple/Flask/ you’ll get list of Flask version

---

Using pip

Apparently if you put unknown version to pip install, it will throw an error and give you list of available version you could install instead.

$ pip install flask==randomwords

This will give you

Could not find a version that satisfies the requirement flask==randomwords (from versions: 0.1, 0.10.1, 0.10, 0.2, 0.3.1, 0.3, 0.4, 0.5.1, 0.5.2, 0.5, 0.6.1, 0.6, 0.7.1, 0.7.2, 0.7, 0.8.1, 0.8, 0.9)
