Long before, I always install mitmproxy using pip. Think like some kind of stable  
sudo -H pip install mitmproxy.

But it always give me 0.17 version. We know that mitmproxy master is updated to 0.18. I want to check if this version fixed the Facebook cannot logged in or Gmail cookie disabled error. So I install from master clone.

##### Steps to reproduce the problem:

I am using LinuxMint 18, I had virtualenv installed.

1. I clone the repo: `git clone https://github.com/mitmproxy/mitmproxy`
2. cd mitmproxy
3. Run the [dev.sh](http://dev.sh) from terminal  
sudo -H ./dev.sh

##### What is the expected behavior?

It will install mitmproxy properly.

##### What went wrong?

The installation run for a short time, but it got an error “Failed building wheel for brotlipy”.  
This is the full terminal output:  
$ ./dev.sh

##### Any other comments? What have you tried so far?

I tried to reinstall virtualenv, update pip to latest version 8.1.2, or run the [dev.sh](http://dev.sh) with `sudo -H` but its keeping happen.

I findoud this is because missing g++.  
Solution is install g++ package:  
`sudo apt-get install g++`

Thanks for the report. This is fixed on [http://docs.mitmproxy.org/en/latest/](http://docs.mitmproxy.org/en/latest/) now, and will be part of [http://docs.mitmproxy.org/en/stable/](http://docs.mitmproxy.org/en/stable/) with the next release 🙂
