Got error "gaierror: [Errno -2] Name or service not known" when run py.test


#1

I am trying to install mitmproxy following the readme.md at master. After the dev.sh finished, I run py.test and got this error “aierror: [Errno -2] Name or service not known”. I am not familiar with python, so could you help me how to solve this?
This is the full terminal output of py.test.

(venv) Vostro-2420 ~/mitmproxy $ py.test

I know this late but I too had the same error today. Check the contents of your /etc/hosts file ‘localhost’ may not be written in front of ::1 . I had ip6-localhost
To fix this just add ‘localhost’ to the line starting with ::1


Serving on IPv6
