RefinedSoftwareLLC commented 2 weeks ago

Issue description

Using ipython magic-action %%script to call modular's magic shell gives an error (see steps to reproduce).

Steps to reproduce

Using ipython magic-action %%script to call modular's magic shell, while offline, running a no-op comment line of #, I get the following error:

Error starting shell: Not a tty (os error 25)

    310     # If we get here and p.returncode is still None, we must have
    311     # killed it but not yet seen its return code. We don't wait for it,
    312     # in case it's stuck in uninterruptible sleep. -9 = SIGKILL
    313     rc = p.returncode or -9
--> 314     raise CalledProcessError(rc, cell)

CalledProcessError: Command 'b'#\n'' returned non-zero exit status 1.

The following works just fine: %%bash, %%python, %%script bash, %%script python.

Reproducible in notebook: https://www.kaggle.com/code/michaeldgibson/offline-mojo-template/notebook?scriptVersionId=194491514

After calling %alias_magic --cell mojo script -p 'magic shell', new notebook cells can start with %%mojo which should compile the cell for mojo once these errors are able to be fixed.

magic run mojo main.mojo

/kaggle/.magic/envs/default/bin/mojo-lldb: /opt/conda/lib/libtinfo.so.6: version `NCURSES6_TINFO_6.2.20211010' not found (required by /opt/conda/lib/libncurses.so.6)

I have one notebook with that checksum that is working, and another with the same checksum that is not. The error message says the file is missing, but it is there.

How do I even troubleshoot this?
