Unable to install python3 package via pip

Question

I am currently moving from Python 2 to Python 3, and I found that one of the packages that I use is currently in Python3 only through a pull-request .

So, I decided to checkout the repository, and checkout the pull-request. I checked and this pull-request only updates a .py file which contains all the coding for the package.

Then, I tried to install the package (being on my computer locally) with pip:

python .\Scripts\pip3.exe install --upgrade --no-index --find-links=. C:\Users\DASTe\PycharmProjects\pyosc

However, I'm getting the following error:

Looking in links: .

This happens in the setup.py file from the package. I have googled, and it appears that in Python 3, the relative imports are done using from . import OSC from . import OSC . However, when I switch that line from setup.py , I get another error:

File "C:\Users\DASTe\AppData\Local\Temp\pip-req-build-7g6v4fwu\setup.py", line 5, in <module>
        from . import OSC
    ImportError: cannot import name 'OSC' from '__main__' (C:\Users\DASTe\AppData\Local\Temp\pip-req-build-7g6v4fwu\setup.py)

Any clue, please?

Many thanks!

It looks like this library has not been maintained since 2011. The pull-request you linked has not been reviewed.

In the short term, I would remove the line import OSC from setup.py and replace OSC.version with ("0.3","6", "$Rev: 6382 $"[6:-2]) , see if it works.

In the long term, I think you will have to take over maintaining this project yourself if you want to keep using it.
