The change to `requirements.txt` in 2e7e82b114a5c1b3eb61f171c376e1cf85563d07 specifies that both `gitdb2` and `gitdb` be installed. As installation packages they share the same name and step on each other. This breaks the use of the module like this: ``` Python 3.5.2 (default, Nov 12 2018, 13:43:14) [GCC 5.4.0 20160609] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import gitdb Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named 'gitdb' ```
