error encountered while installing ncvx

[RandyChen233]

Hi,

I have successfully installed scsprox, but when I tried installing ncvx using pip, the following occured:

(ICON_lab) randychen233@Randy-Desktop:~/projects/ICON_lab/ncvx$ pip install ncvx
Collecting ncvx
  Using cached ncvx-0.2.0.tar.gz (12 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py egg_info did not run successfully.
  │ exit code: 1
  ╰─> [1 lines of output]
      error in ncvx setup command: use_2to3 is invalid.
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I also tried installing from source, but another error occurred:

(ICON_lab) randychen233@Randy-Desktop:~/projects/ICON_lab/ncvx$ python setup.py install
error in ncvx setup command: use_2to3 is invalid.
