I have been using python3 + flask, before. I recently watched a project video of Django. There are all kinds of problems in configuring the environment when python2.7 uses django on win10. There are problems in installing mysql-python and ansible packages with pip, and there are all kinds of errors. I can say that I have no problem installing ansible with python3 on win10. The following is an error report. I have no idea what the cause of the problem is.
