I use pyinstaller to package my application, like this below,

`pyinstaller semi-auto_configuration_checker/proxy_checker.py`

but error occurred here:

```
Failed to execute script proxy_checker

```

it is impossible to add these templates of mitmproxy onto the \*.spec files, I think.

You can see how we build our binaries in [https://github.com/mitmproxy/mitmproxy/tree/master/release](https://github.com/mitmproxy/mitmproxy/tree/master/release). Building binaries is a fairly brittle process with PyInstaller, so I would very much recommend looking into other options for distributing your software.
