BUG: not able to detect local packages

[yfiua]

I have pandas installed

> pip list | grep pandas
pandas                        2.2.0

but pipreqs is not able to detect it and tries to resolve it via PyPI. Why?

> pipreqs . --print

INFO: Not scanning for jupyter notebooks.
WARNING: Import named "pandas" not found locally. Trying to resolve it at the PyPI server.

@yfiua I had the same "Not scanning for jupyter notebooks" warning, and around half of the imported packages were missing. You need the following command, which enables scanning of Jupyter notebooks:

pipreqs --scan-notebooks .

After adding this option, I still get the "not found locally" warning for a few packages, but the resulting requirements.txt file is complete and correct, except for the pandas version. I have pandas 2.2.1 installed, but pipreqs lists 2.2.2 in the generated file.

The warning messages I get are below for the devs' reference, if needed:

WARNING: Import named "numpy" not found locally. Trying to resolve it at the PyPI server.
WARNING: Import named "numpy" was resolved to "numpy:1.26.4" package (https://pypi.org/project/numpy/).

For me it is not related to --scan-notebooks because I have no notebooks. Adding --scan-notebooks does not solve the problem

[AhmetZamanis]

I see, I assumed the warning is only displayed when there are notebooks in the project. My mistake.

I have the same problem, it recognise well some packages but not polars niether pandas

[VishalSharmaCode]

Use conda install anaconda::pandas command into jupyter command terminal

[yfiua]

Use conda install anaconda::pandas command into jupyter command terminal

The issue is not related to conda, nor jupyter. pipreqs should work without conda or jupyter.

Same issue here, was anyone able to solve it?

[itanfeng]

Same problem. The versions are not match. It always generates the package's version through resolving the the PyPI server instead of the ture local package's version.

I also observe this problem.

For an arbitrary project, I call

pipreqs path/to/project --savepath="req.txt"

I get the warnings:

...
WARNING: Import named "scipy" not found locally. Trying to resolve it at the PyPI server.
WARNING: Import named "scipy" was resolved to "scipy:1.14.1" package (https://pypi.org/project/scipy/).

I have a modified PYTHONPATH, and I use pyenv... In case this is relevant for debugging...
