Problem: I am trying to run a python3 script that imports HTSeq, but I have a conflict regarding the "build directory."

Background: I have set up a python3 conda environment on my Ubuntu virtual machine. I git cloned the python2 package, and pip installed the requirements.txt, yet when I go to run the python script I get the following error message:

Traceback (most recent call last):
  File "guideseq/guideseq.py", line 22, in <module>
    from umi import demultiplex, umitag, consolidate
  File "/home/james/Bioinformatics/softwares/guideseq/guideseq/umi/consolidate.py", line 6, in <module>
    import HTSeq
  File "/home/james/.local/lib/python2.7/site-packages/HTSeq/__init__.py", line 12, in <module>
    raise ImportError( "Cannot import 'HTSeq' when working directory is HTSeq's own build directory.")
ImportError: Cannot import 'HTSeq' when working directory is HTSeq's own build directory.

Attempted Solution I have tried uninstalling and reinstalling the required HTSeq version from this directory:

~/.local/lib/python2.7/site-packages/HTSeq

My search has not yielded any questions such as this. I hope I can please get some insight. Thank you!

Additional info: I was able to install the requirements. Traceback:
