Errors Running

I am getting the following error message when running

Command “/home/chase/mitm/mitmproxy/venv3.5/bin/python3.5 -u -c “import setuptools, tokenize;file=’/tmp/pip-build-hz5dkw6k/cryptography/’;f=getattr(tokenize, ‘open’, open)(file);’\r\n’, ‘\n’);f.close();exec(compile(code, file, ‘exec’))” install --record /tmp/pip-v57hqv3e-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/chase/mitm/mitmproxy/venv3.5/include/site/python3.5/cryptography” failed with error code 1 in /tmp/pip-build-hz5dkw6k/cryptography/

On Ubuntu16.04

Any ideas on what could be wrong ?

This fails on installing cryptography: - if you can get that installed cleanly, installing mitmproxy should work.


Maybe this will help you:

Thanks for the help. I was only installing cryptography for python2.
#pip3 install cryptography
This worked installing using pip3 (installing for python3.)
