Installation issue: unwanted skbuild printout

[cterrill26]

When i import skbuild with python3 on my system I get the following printouts:

>>> import skbuild
Generating grammar tables from /usr/lib/python3.8/lib2to3/Grammar.txt
Generating grammar tables from /usr/lib/python3.8/lib2to3/PatternGrammar.txt

This causes issues in python/CMakeLists.txt since line 48 is not expecting this extra printout.

Locally, I have fixed this by replacing the import skbuild at line 39 of the script with import sys; temp = sys.stdout; sys.stdout = open(os.devnull,\"w\"); import skbuild; sys.stdout = temp to silence the output.

Hi, and thanks for posting this issue. Could you share the error that you are getting? Also, perhaps you could try this solution and let us know if it helps?

The error message is:

CMake Error at python/CMakeLists.txt:49 (message):
  Expected CMake module path from

                         scikit-build at Generating grammar tables from /usr/lib/python3.8/lib2to3/Grammar.txt

  Generating grammar tables from
  /usr/lib/python3.8/lib2to3/PatternGrammar.txt

  /aha/lib/python3.8/site-packages/skbuild/resources/cmake

As I said, this is due to the extra printout of

Generating grammar tables from /usr/lib/python3.8/lib2to3/Grammar.txt
Generating grammar tables from /usr/lib/python3.8/lib2to3/PatternGrammar.txt

when importing skbuild, which can be seen in the error message. When silencing this output the installation works fine.

Thanks. The fix looks reasonable, as we would not miss errors, just stdout. Would you be willing to submit a PR with this fix?
