fava not working in winpython

[holahapi]

I'm new to beancount and Fava

I'm a beginner with beancount and Fava.

When attempting to run them in WinPython (portable Python), the server only shows a blank page.
What could be causing this issue?

You need to change the win's registry to do so,I did this successfully.
like this #1446 (comment)

Thanks for your help! I'd rather not touching the registry. I'll just wait for the problem to be fixed. Thanks again!

A workaround was added for that issue in #1672, so that shouldn't be causing it.
Does the browser console show any errors or other logs? Does the Fava application log any errors? Which versions did you install?

[holahapi]

the version that i use are

Python                        3.9.10
beancount                     2.3.6
fava                          1.27.3

when i run in the console, it shows

Microsoft Windows [Version 10.0.19045.3570]

D:\folder\folder2>"B:\folder\winpython\_mainApp\WPy64-39100\python-3.9.10.amd64\Scripts\fava.exe" -p 44444 "D:\folder\beancount_accounting\simple\basic.beancount"
Starting Fava on http://127.0.0.1:44444

when i open the url, it display an whole white page, the chrome console shows:

:44444/static/app.js?mtime=1714918753:1 Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.

mhh, so that workaround does not seem to be working - can you try fixing your registry or seeing whether it works with a more up-to-date Python version.

What does the following Python script output?:

import mimetypes

print(mimetypes.guess_type('app.js'))
print(mimetypes.types_map.get(".js", ""))
mimetypes.add_type("text/javascript", ".js")
print(mimetypes.guess_type('app.js'))

[holahapi]

import mimetypes

print(mimetypes.guess_type('app.js'))
print(mimetypes.types_map.get(".js", ""))
mimetypes.add_type("text/javascript", ".js")
print(mimetypes.guess_type('app.js'))

output

('text/plain', None)
text/plain
('text/javascript', None)

After further testing, I found out that WinPython 3.9 works with Beancount and Fava in VMware Workstation.

I guess the issue was caused by having another Anaconda Python installation.
