Hi Sena,

Please run

pip install requirements-parser
python tools/build_versions.py

Please provide the output of build_versions.py

Can you somehow post the full output of the command?
Maybe to pastebin?

Hi Juan,

Yes, I did install Cython first before attempting to “pip install -e .”

Hi Sena, thanks for wanting to contribute!

I believe you need install Cython first, and then it should work. Can you give that a try and report back?

Juan.

Hi,

I am trying to make a contribution to the scikit-image documentation. In my attempt to setup the environment after creating it, I keep getting an error(see below). This error happens when I do "pip install -e ." in the cloned scikit-image. I’m doing this on a linux machine.

error: Command "gcc -pthread -B /home/liulab/anaconda3/envs/skimage/compiler_compat -Wl,--sysroot=/ -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/tmp/pip-build-env-29p1x6uy/lib/python3.6/site-packages/numpy/core/include -I/tmp/pip-build-env-29p1x6uy/lib/python3.6/site-packages/numpy/core/include -I/home/liulab/anaconda3/envs/skimage/include/python3.6m -I/home/liulab/anaconda3/envs/skimage/include/python3.6m -c _extrema_cy.c -o build/temp.linux-x86_64-3.6/_extrema_cy.o -MMD -MF build/temp.linux-x86_64-3.6/_extrema_cy.o.d" failed with exit status 1

Please advise on what I should do to solve the issue and let me know if you have any questions.

Thanks,

Sena
