Exclude certain dependency version ranges in setuptools/pip

Question

Currently the Django Project supports 1.4, 1.7 and 1.8. In my setup.py I want to reflect these versions as being supported.

install_requires=[\'Djan         


        

Answer 1

You can use Django>=1.4.2,<1.9,!=1.5.*,!=1.6.*

This is defined inside PEP440.

You can test this behavior with the packaging module that is vendored inside the last versions of setuptools and pip.

In [1]: from packaging import specifiers

In [2]: sp=specifiers.SpecifierSet(">=1.4.2,<1.9,!=1.5.*,!=1.6.*")

In [3]: sp.contains("1.4.2")
Out[3]: True

In [4]: sp.contains("1.6.4")
Out[4]: False

In [5]: sp.contains("1.8.2")
Out[5]: True
