Error in pip install datefinder

问题

While I was trying to pip install python package "datefinder", I met the error about regex and visual c++. I have viewed lots of Stackoverflow posts and cannot find a solution yet. One post is similar but got no reply. Any comment is appreciated!

There is hardcoded value of regex version in setup.py. You need to download source code from https://github.com/akoumjian/datefinder and change regex version from regex==2016.01.10 to regex>=2016.01.10 or your latest. e.g.:

line 85: install_requires=['regex>=2016.01.10', 'python-dateutil>=2.4.2', 'pytz'],

Then install with

pip install ./path_to_datefinder_source
