web.zip

Expected behavior
Startup of my application

Screenshots

Desktop (please complete the following information):

• OS: Windows 10
• Browser chrome

Additional context

I think pyinstaller doesn't add eel.js. But I wasn't able to find why it doesn't add.
Let me know if you need some help on this issue.

** What I did to solve this
It was my eel folder of output folder. (i.e output\app\eel)

I was able to solve this issue by manually adding to eel folder from github eel folder

Thank you,
Antonio

Yes, you are correct. Pyinstaller can't find eel.js so you have to help it by saying pick eel.js from this location. There are 3 ways to do this:

1. If you are using auto-py-exe, then in the add datas place, add the location of eel.js (../site-packages/eel/eel.js)
2. Or, directly add that location under datas in the .spec file generated by pyinstaller.
3. Or, you could refer to eel's readme here. That handles all that automatically, so you won't have to worry about it.

Third Option was very helpful for me.
But I guess many people can miss that option like me.
I think it is better to automate that process in pyinstaller as well.
Like creating js script via python script.

Well, agreed. Ideally someone should write a pyinstaller hook for eel and submit a PR to pyinstaller team.

Thanks @RahulBadenkal for helping @jhyunetp get to the bottom of this problem. I'm going to close this issue off for now - but am going to look at proposing a hook for pyinstaller. It doesn't look too tricky.

Hi @asdat3. Rather than using pyinataller directly, please instead use 'python -m eel' to package your app.

We've submitted a pyinataller hook that should make this less error prone in the future, but it hasn't yet been made available in a release. It should be coming soon.

Hi, @samuelhwilliams
dont realy get it, what does the python -m eel command package? where to launch it?

[samuelhwilliams]

Could you open a new issue and include the code you're running and the command, etc? Then we can provide more help. Thanks!
