How to install poppler correctly for pdftotext - docker-compose

Question

When I try to build my docker-compose pdftotext seems to fail with this error:
Running setup.py install for pdftotext: finished with status 'error'
ERROR: Command errored out with exit status 1:

I've tested this on windows and linux with the same error. Has anyone found a fix for this?

Unfortunately, it is hard to help without knowing the content of your docker-compose/Dockerfile. But as mentioned in the error message, you are missing pkg-config. You should try to run apt-get install pkg-config.
