AttributeError: 'NoneType' object has no attribute 'split'

[lsq2020]

Hello, I used Pyaging=0.3.6, but I could not install the package. I tried three methods in the help documentation, and all errors occurred:
AttributeError: 'NoneType' object has no attribute 'split'
I guess the reason is that the dependency package pybigwig package cannot be installed. Is there any solution? I use windows system
The error is as follows:

Thankyou！！

Hi! Thanks for bringing this up.

Could I check which version of python you are using? Currently pyaging only works on 3.9-3.11.

[osbornzhou]

pip install pyaging in python 3.9-3.11 all have this problem, maybe something wrong in setuptool?

[lcamillo]

I would recommend installing pyaging with poetry rather than with pip. Perhaps creating a new conda environment would help -- the GitHub tests passed in Windows and Linux for python 3.9-3.11.

Could you provide more details of your OS?

Thank you!

Thank you!

i use anaconda in win11! thx

[osbornzhou]

i use poetry to install, and with the installing of pyaging, pybigwig==0.3.22 counter the same problem, thx

[GillianGrayson]

Any updates here?
It is impossible to install one of dependencies (pybigwig) on Windows OS.
Is pyaging supported only for Unix/Linux? Maybe it will be useful to add a disclaimer about supported OS in the package description?

[lcamillo]

Apologies for the delay! I'm planning on making the pybigwig dependency optional this weekend. It should run just fine on Unix/Linux.

[GillianGrayson]

Thank you so much!
I'll be waiting for it!

[lcamillo]

Apologies again for the delay. I have now made pyBigWig optional (only needed for the histone mark clocks). Could you let me know if the issue has been fixed? Thanks!

[GillianGrayson]

Thank you so much!
Everything works perfectly now! Tested all Homo Sapiens DNAm clocks with custom dataset.
Will cite you in future papers.

[lcamillo]

Great to hear! I'll close the issue now but feel free to open another one in case something is not working! Thanks again for flagging it.
