Cannot install DCCP

[anhphuong-ngo]

I tried to install dccp by using pip as well as with downloaded package, but it didn't work for me. Note: CVXPY works for me. Thanks

(base) PS C:\Windows\system32> pip install dccp Collecting dccp Using cached dccp-1.0.4.tar.gz (8.0 kB) Preparing metadata (setup.py) ... error error: subprocess-exited-with-error

  The above exception was the direct cause of the following exception:

Hi @vnscnap, what error did you get when you installed the downloaded package using python setup.py install? And what versions of Python and setuptools did you use?

Thanks for your response @xinyueshen When I tried to install with python setup.py install, it showed the setuptools is incompatible. I use Python 3.9, and setuptool 65. I tried to downgrade the setuptools to 58, but it's not successful.
