Trying to import mitmproxy into python3 project

Hi There,

We are trying to use mitmproxy for our internal testing tool which written in Python3.
Then I do from mitmproxy import flow it doesn work( not importing) We are -reusing flow.FlowReader part .
Can you please help and advice how can we setup mitm with python3 for development.
If I do pip install mitmproxy its installing/importing only mitm.0.15. Is it a way, hack it so we can use it ?

I’m not sure is it a clear question , but basically if I have line like this : from mitmproxy import flow python will throw an ImportError.

Thank you,

The first version to support Python 3 will be 0.18. We’re somewhat close to a release, but you’d need to use the master branch for now. :slight_smile:

@mhils thank you for a quick response. Can I just ask for quick clarification to setting this up.
I clonned master mitm in my project. I run python3 install .
my python version is 3.5.2
But I’m getting a huge stack trace message . Like below :

        File "/var/folders/7b/kg453htd1pl5v_cv691p546h0000gn/T/easy_install-6c2f1s5g/Pillow-3.3.1/", line 521, in build_extensions
        ValueError: jpeg is required unless explicitly disabled using --disable-jpeg, aborting

        During handling of the above exception, another exception occurred:

        Traceback (most recent call last):
          File "", line 123, in <module>
            "pytz>=2015.07.0, <=2016.6.1",

@blahblahuser: You are missing dependencies from Pillow, if you google the ValueError: jpeg is required unless explicitly disabled using --disable-jpeg you should find what you need. The dependencies mentioned on should cover everything. :slight_smile:

@mhils thank you I 've fixed , should have close this question .
But today I’m trying to setup Dockerfile and running into the error
on ubuntu:trusty by running a python3 install :

You are missing dependencies. Check our install section in the docs. :slight_smile:
