This is bug #897 (fixed in bcf9f1c). The solution is to upgrade GitPython to version 2.1.15 or higher.

If at all possible, a much higher version should be used. The current version of GitPython, as of this writing, is 3.1.42. Over time, bugs have been fixed, including security vulnerabilities. Especially if you are developing a web application, it is a good idea to use patched versions of all dependencies (this is not limited to GitPython).

The best way to update may depend on the details of your project and what is causing such old versions to be specified in the first place. It looks like your requirements.txt is generated by running pip freeze. If so, getting later versions comes down to how you are installing packages before running a command like pip freeze >requirements.txt. Maybe you are installing from a requirements.in file that contains unnecessary constraints, but this is just a guess. Or maybe requirements.txt is copied from an older project that has not been updated.

---

In case they are of interest, here are some references related to #897 itself:

• GitPython not available for Python 2.7 #897
• bcf9f1c (Require gitdb2 <3) - fix by Harmon758
• Comment on #897 by Harmon758 about the fix
• gitpython-developers/gitdb@c412680 (Remove Python 2 compatibility shims gitdb#56) - gitdb.utils.encoding.string_types removed from gitdb/gitdb2
• 768b9ff (Remove Python 2 compatibility shims #979) - when GitPython stopped using it altogether, in version 3.0.6, allowing newer gitdb to be used

However, it will most likely not be necessary to deal with any of those details. Upgrading to 2.1.15 or (preferably) higher should be sufficient.
