shell_magic exception on OSX with zsh
parente opened this issue · comments
Spotted this while working on vericast/spylon-kernel#33. When launching a kernel which loads the shell_magic:
[MetaKernelApp] ERROR | Can't load '/Users/parente/miniconda3/envs/spylon-kernel-dev/lib/python3.6/site-packages/metakernel/magics/shell_magic.py': error: Timeout exceeded.

I'll try to test this in a plain metakernel install. If it's known that pexpect and metakernel aren't py36 compatible, then please disregard.
Not a py36 problem. It's something about pexpect on my Mac. Maybe with the zsh shell, though when I switch to bash I'm able to reproduce it as well.
What version of metakernal are you using? Is it up to date (--update)?
@parente, what happens if you run that command directly? /bin/bash --rcfile /Users/parente/miniconda3/envs/spylon-kernel-dev/lib/python3.6/site-packages/metakernel/bashrc.sh.
@blink1073 That won't work, because bashrc.sh isn't there... it is in pexpect's directory. I recently attempted to make that a bit more robust, but perhaps it isn't working correctly. See ebbeb9a
I appear to be on the latest.
$ conda list | grep meta
metakernel 0.20.1 <pip>
Interestingly, it works fine on my Linux VM. The steps I'm using to create this conda environment are the same on both boxes and captured here: https://github.com/maxpoint/spylon-kernel/blob/master/Makefile#L21
I'll try hacking in a few debug statements to see how that __file__ import resolves.
Ah, ebbeb9a is not in a release yet. That's why. I'll install from master and see if the problem is fixed.
Ah, good catch! Sorry about that.
I tested master. The commit @dsblank referenced does indeed fix the problem. Thanks for the help!
0.20.2 is on PyPI, conda build in progress.
0.20.2 is also on conda-forge
