New description:
#11287 introduced a `runsnake` command that tries to execute `runsnake`
using the system python. However, it does so without `sage-native-execute`
and without clearing `PYTHONHOME` and `PYTHONPATH`, so it has very little
chance of ever working. It already comes a little closer by doing
{{{#!diff
- os.system("/usr/bin/python -E `which runsnake` %s &"%tmpfile)
+ os.system("unset PYTHONHOME; unset PYTHONPATH; sage-native-execute
runsnake %s &"%tmpfile)
}}}
in `sage/misc/dev_tools.py` (that makes the command `runsnake` work on my
computer).
You can't really expect the system python to work properly when the
environment variables point to libraries for other python installs. See
also #9386, #10286, #17735.

Comment (by tmonteil):
See also #17735 that was primarily about docs, checks and preparsing for
`runsnake()`, but discuss similar issues.
