New submission from Kapil Thangavelu <kap...@gmail.com>:
This issue seems to be reported a few times on various githubs projects. I've also reproduced using a brew install of python 2.7.15. I haven't been able to reproduce with python 3.6. Note this requires a framework build of python. Background on the underlying issue cause due to a change in high Sierra http://sealiesoftware.com/blog/archive/2017/6/5/Objective-C_and_fork_in_macOS_1013.html A ruby perspective on the same issue exhibiting for some apps https://blog.phusion.nl/2017/10/13/why-ruby-app-servers-break-on-macos-high-sierra-and-what-can-be-done-about-it/ The work around seems to be setting an environment variable OBJC_DISABLE_INITIALIZE_FORK_SAFETY prior to executing python.
