[PYTHON] Work memo when introducing mitmproxy

I was interested in the articles around here, so I installed it.

Introduction to mitmproxy for mobile app developers Use mitmproxy to force the API of the app to the development environment

I got some errors before the introduction, so I will keep a work record though it is appropriate. Someone who doesn't know python is working, so please let me know if you do something strange.

Rough work

[1] Download and install pip https://pip.pypa.io/en/latest/installing.html

[4] pip install mitmproxy http://qiita.com/hkurokawa/items/9034274cc1b9e1405c68

[5] The version of pyopenssl is said to be old (0.14 or earlier) and does not work https://github.com/dutzi/tamper/wiki/Troubleshooting

--From the pip list, it says 0.14, but I get the above error --Have you seen the old version? When I renamed the old one as shown below, the error disappeared.
