pip-compile error using Anaconda - File "/opt/anaconda3/bin/pip-compile", line 8, in <module> sys.exit(cli())

Question

My pip version is 22.0.4. I had the most recent version but had to downgrad because I noticed the same error mentioned here: https://github.com/jazzband/pip-tools/issues/1617)

When I try to run pip-compile to update the requirements.txt file but I keep seeing the below error:

(base) krs@me-user ds-airflow % pip-compile

EDIT: I just tried running: pip-compile --upgrade

  File "/opt/anaconda3/bin/pip-compile", line 8, in <module>
    sys.exit(cli())
  File "/opt/anaconda3/lib/python3.8/subprocess.py", line 512, in run

EDIT EDIT: I've run conda list '(pip|click)' and see the following, but my requirements.txt file has hundreds of packages:

# packages in environment at /opt/anaconda3:
#
# Name                    Version                   Build  Channel

click-default-group       1.2.2                    pypi_0    pypi
clickclick                20.10.2                  pypi_0    pypi
pip                       20.2.4                   pypi_0    pypi
pip-tools                 6.6.0                    pypi_0    pypi

Answer 1

The version combination of pip=20.2.4 and pip-tools=6.6.0 is not compatible. Either upgrade pip to >=21.2, or downgrade pip-tools to 5.5.
