How to settle this pyinstaller error?

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
Traceback (most recent call last):

ValueError: dataPath: /Users/bill.li/dist/proxy_checker/mitmproxy/onboarding/templates does not exist.

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. Building binaries is a fairly brittle process with PyInstaller, so I would very much recommend looking into other options for distributing your software.
