Requirements problems

[NicolasMICAUX]

Hi,
I ran
git clone https://github.com/Zain-Bin-Arshad/pdf-viewer.git cd pdf-viewer/ pip install -r requirements.txt

i got errors :
Traceback (most recent call last): File "pdfviewer.py", line 40, in <module> import fitz File "/xxxxx/venv/lib/python3.8/site-packages/fitz/__init__.py", line 1, in <module> from frontend import * ModuleNotFoundError: No module named 'frontend'
related to https://stackoverflow.com/questions/56467667/how-do-i-resolve-no-module-named-frontend-error-message

you also forgot to mention the python version you're using. I think it's 2.7 ?

Using python 2.7 venv, pip install -r requirements.txt returns compilation errors on linux.

I was very impressed by your PDF viewer screenshots, so I would love to use your code.

Thx a lot.

Hello, I used python 3.7.4. Thanks for the remainder I added this to the README file. Talking about your issue, follow the steps mentioned in the link that you already mentioned. I remember that I faced similar issue and I followed solution mentioned here: https://stackoverflow.com/questions/56467667/how-do-i-resolve-no-module-named-frontend-error-message and it solved my issue.

As stated there the issue is that there is a package named fitz on PyPI. Because PyMuPDF uses the same name, fitz, as its top-level text, both packages cannot co-exist in the same Python. Let me know if have any other issue. Thanks

Thanks you so much for answering so fast. Testing all this tomorrow and I tell you. Thx a lot.

I solved the error by running pip install PyMuPDF==1.16.14.
The other solutions (just pip install PyMuPDF or changing from frontend to fitz.frontend didn't work for me)

I also downgraded my python version from 3.8 to 3.7 but not sure that is the pb

Again thx you !
