Got Problem Installing requirements.txt

weantony commented 3 years ago

Hi Everyone,

I am a beginner in python. I got some problem in installing requirements.txt file. Could someone give some advice please? The entile code is listed below. It looks like there are two errors. The first one is failed to build wheel for pynumpress and the second one is failed to run setup.py for pynumpress. I did have installed visual studio 2019 and wheel already.

Thank you very much in advance.

Hi weantony,

you can try to install the packages individually to see if that solves it, even though it's fairly unlikely: pip install numpy Installing numpy first and then pynumpress makes sense I think pip install pynumpress Installing pynumpress without the version specified may help as well. But in the end it looks mostly like a Windows issue and I'm not sure how to fix that. Maybe someone else has a idea?

Hi weantony,

may be related to the the PATH variable, which has to be edited.

Hi StSchulze

Thank you very much for your suggestion. I tried to install pynum and pynumpress seperately. I think the problem comes from installing pynumpress. The error message listed below is what I got from installing pynumpress. It looks quite similar to what I got from installing requirements.txt. However, I am still trying to figure out what the problem is.

Hi,

have you tried the suggestion of @JB-MS ? If that doesn't work either, you might want to open an issue in the pynumpress repo directly. I'm tagging @mobiusklein in case he has a quick fix for it?

Best, Stefan

mobiusklein commented 3 years ago

I haven't encountered this problem on Windows before. It looks like the include path is being specified correctly, but let's check. If you go to C:\Users\weant\AppData\Local\Programs\Python\Python38\include, do you see the file Python.h in that folder?

Hi StSchulze,

Thank you very much for the reply. I am really sorry I am not able to make very quick reponse because my knowledge related to programing and CS is very limited. I tried to read the suggestion of JB-MS, but I honestly still can't understand the contend of it. Instead I tried to installed python and visual studio 2019 in the same way on another laptop with win 10 Enterprise. After trying pip install install -r requirements.txt, the error became Preparing wheel metadata... error. But pynumpress was successfully installed. So I guess the problem why I can't install pynumpress is related to certain setting or path somewhere. I am still trying to figure things out.

Thank you very much for reaching out and help.

Hi mobiusklein,

I didn't even find a filefolder named inclue in C:\Users\weant\AppData\Local\Programs\Python\Python38. I can find this folder and python.h on my other labtop which install python. Do I need to remove and install python on my pc or just add something to it please? Thank you very much for reaching out and help.

mobiusklein commented 3 years ago

I've just uploaded a Python 3.8 Windows wheel for pynumpress, so you should be able to install that at least without needing to make any changes to your system now.

That you can't find C:\Users\weant\AppData\Local\Programs\Python\Python38\include explains why building pynumpress failed. I can't imagine why the folder would be missing, either. In theory, you could just copy over the include folder from another known good copy of Python 3.8, but this assumes no other part of your Python installation is unexpectedly missing.

The include folder isn't necessary unless you need to install a package with a C extension from source again, like you're trying to do with pynumpress.

Hi mobiusklein,

Thank you so much. I tried python -m pip install pynumpress again and nothing changed. But I think I should reinstall the python first to make it right first. I'll let you know if there's any progress on that. Thank you so much for your help.

Hi mobiusklein,

I have reinstalled python 3.8.0 and include filefolder showed up. The installation of requirements.txt and setup.py are successfully finished. Thank you very much for all your kindness help. May I further ask what does tox mean in test the package and correct installation please? It seems the tox file in pymzML could not just run by python code. Thank you again for your help.

mobiusklein commented 3 years ago

Happy to help.

tox is a tool for testing automating testing Python programs across multiple Python versions/environments. It's useful for proving that the program. I don't think you need to worry about it for the moment, unless you plan to make substantial changes to pymzML itself.
