python manage.py runserver, shell, dbshell freezes on git-bash

Question

I'm trying to run the interactive shell in python virtualenv in windows, on git-bash, but it isn't running. Strange thing is, it doesn't seem to do anything, just the cursor is blinking on the next line, giving no output.

$ python manage.py shell
|

However, I'm able to run commands like - migrate, makemigrations, sqlmigrate. Problem is occurring with the commands - shell, dbshell, runserver.

This seems to be some git-bash related issue, because I'm able to run shell from command line. I'm using PortableGit-2.4.3.1-2nd-release-candidate-64-bit.7z.exe on windows.

I guess simply `python manage.py shell_plus` does not work right? — vabada, Jun 24 '15 at 14:25
@dabad Nope. That doesn't. But it shows some output regarding deprecation. — Rohit Jain, Jun 24 '15 at 14:29
If I have problems with hung programs, I usually try [PyStuck](https://github.com/alonho/pystuck) on them... Can you get any stack output from that to show what's going on? — Peter Brittain, Jun 26 '15 at 16:56
@PeterBrittain Well, I installed PyStuck, and IPython also got installed with it, with which it's working. — Rohit Jain, Jun 27 '15 at 08:29
OK, so that path won't help... Does it still reproduce without pystuck or has the IPython installation fixed your issue? — Peter Brittain, Jun 27 '15 at 09:27
@PeterBrittain Actually with IPython, the issue seems to be resolved. — Rohit Jain, Jul 01 '15 at 05:59
Weird. I wonder if there's any undeclared dependency in there... Writing up what we've found as a formal answer. Let me know if there's anything else you think I should put in there. — Peter Brittain, Jul 01 '15 at 06:31

The problem is python.exe itself has issues with gitbash. Supposedly, it has something to do with the ncurses library.

The solution is to type "winpty python.exe" instead of python. "winpty python.exe manage.py shell" should work. You can also create an alias to bypass the issue. Typing "alias python='winpty python.exe'" will make it so "python manage.py shell" works as it should.

This answer explains it better: Python not working in the command line of git bash

Summarising the investigation in the comments...

A good way to investigate these sorts of problems is to use pystuck.

In this case, it would appear to have been some sort of internal dependency on IPython as installing pystuck also installs IPython and the bug no longer reproduces with Both installed.

Well, I'll accept this answer for now, as it got me moving ahead with my work at least.. Still have to see why it didn't work with built-in python interpreter. Will play around with pystuck when I get some time. Meanwhile, thanks for your answer :) – Rohit Jain Jul 01 '15 at 07:50
@Rohit Jain: Yeah - it's less than satisfactory to me too, so I had a quick look at the [code](https://github.com/django/django/blob/8047e3666b0b50bb04e6f16c2a4fb21ddfd5713f/django/core/management/commands/shell.py). Looks like IPython will be used in preference to bpython and then ultimately the code module. My guess is that you have a dodgy bpython installation. – Peter Brittain Jul 01 '15 at 09:28

I don't have idea for the commands shell, and dbshell, but for runservercommand, I had same issue. I solved running

python manage.py runserver --noreload
