lispy--eval-python seems to fail when there is no output

[guibor]

1==1 ---> True printed in minibuffer a =1 ---> Crashes shell

I get NameError: name ’lp’ is not defined

and then the shell becomes read-only

The should be fixed now, if you update from MELPA. You should have this file: elpa/lispy-20191016.1250/lispy-python.py. That's what lp should point to.

Thanks. I actually updated right after experiencing the issue. A silly question - for some reason when I install from MELPA lispy-python.py does not appear in the folder (even though it does if I clone the repo or at the .cache/build if installed from quelpa). Maybe this is why this isn't working for me.

Correction, the file (lispy-python.py) is actually in the right folder yet the error persists.

Here is what I had to do to make this work again - added in my python shell startup script:

lispy_dir = '/full-path-to-home/.emacs.d/.cache/quelpa/build/lispy/lispy-python.py' import imp lp = imp.load_source('lispy_python', lispy_dir)

In addition, I had to remove the following line that were run as part of python-hook: In addition, I had to remove this from my python-hooks (implementing a suggestion from https://github.com/jorgenschaefer/elpy/issues/924 in a way that would not interfere with lpy - but it looks like it does interfere somehow, even though elpy only uses python-shell-send-string-no-output)
