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. 🙂

@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 setup.py 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/setup.py", 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):

```

@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 [http://docs.mitmproxy.org/en/stable/install.html](http://docs.mitmproxy.org/en/stable/install.html) should cover everything. 🙂

@mhils thank you I 've fixed , should have close this question .

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