Could not install packages

[chengl-amd]

Hi, when I perform:

pip install -r requirements.txt

Error comes out as:
Processing /home/ktietz/src/ci/alabaster_1611921544520/work (from -r requirements.txt (line 6))
ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: '/home/ktietz/src/ci/alabaster_1611921544520/work'

requirements.txt refers some package paths that don't exist in my local PC.
