Segmentation fault (core dumped)

I can't get the core dump log of virtualenv.

flake8 version:

3.7.8 (mccabe: 0.6.1, pycodestyle: 2.5.0, pyflakes: 2.1.1) CPython 3.7.0 on Linux

All code is running inside docker container, with python 3.7.0.


Solution

  • According to the issue in flake8 repository, there are some unexplained bugs in unofficial python versions. I fixed it by creating a new virtual environment, with python3.7.5 built by pyenv.
