Can't install ZXing - FileNotFoundError "requirements.txt"

[Fellow-Bennse]

Hello there

I am trying to install ZXing on Python 3.10.6 and it fails on a Sub-Process when trying to get requirements to build the wheel:

"FileNotFoundError: [Errno 2] No such file or directory: 'requirements.txt'"

Not quite sure what the Problem is in this case, or what I can do to fix it. I have OpenJDK 21.0.2 installed via Brew

"FileNotFoundError: [Errno 2] No such file or directory: 'requirements.txt'" I am also facing the same issue my python version is 3.10 and openjdk version "11.0.21" 2023-10-17 in my ubuntu 22.04

Hmmm… exactly how are you attempting to install it? From local source, or what? More details please.

Same issue here. Steps to reproduce:

wget https://files.pythonhosted.org/packages/4b/ad/8e74e1a027c90baf7ba17760a80afe0a7f7b63725035d1f152a75e801b62/zxing-1.0.2.tar.gz
tar -xvzf zxing-1.0.2.tar.gz
cd zxing-1.0.2
python setup.py bdist_wheel

The URL is the one from https://pypi.org/project/zxing/#files FWIW, the previous version sdist, zxing-1.0.1.tar.gz has the same problem

@dlenski well, as it's mentioned on pypi with: pip install zxing (due to my setup pip is the same as pip3)

But as lowvoltage mentioned it also fails through the other way

I used pip3 install zxing . this command raised the above FileNotFoundError.

I have the same problem using the automated install pip install zxing I could solve it, by manually download and extracting the version from GitHub, and install it manually: pip install python-zxing-1.0.2/

[PushpakBhoge512]

yes the wheel has some issues I am using this command it is working fine

pip install 'zxing @ git+https://github.com/dlenski/python-zxing.git@v1.0.2#zxing'

I just stumbled upon this as well, which is even more annoying as the requirements.txt is empty anyway (although we probably get the same issue for the requirements_dev.txt file not required for PyPI users). Adding the requirements*.txt files to a MANIFEST.in file should solve this issue.

Having same problem with 1.0.2 If someone need an easy way of getting a working version until this is fixed: pip3 install zxing==1.0.1

Thank you @stefan6419846!

I'm going to go with this small incremental fix, rather than your slightly more involved solution in #37.

I probably need to catch up in my knowledge of more modern Python packaging approaches and tools :sweat_smile:

Closed in c707794 / v1.0.3. Should be possible to use pip3 install zxing again, and it will Just Work™.

No worries, this is perfectly fine for me. I just wanted to check correct packaging as well. The build-based approach is the recommended way for generating distributions without having to care about the build backend itself.

This is where I avowedly need to do something like a decade's worth on catching up on the state-of-the-art of Python packaging.
