Error in manage.py runningerver with Django on windows 8.1
I couldn't find this exit code anywhere, but hopefully one of you could help me or let me know if it's a bug in python / Django.
Anyway, here's the stacktrace first:

UnicodeEncodeError: 'mbcs' codec can't encode characters in position 0--1: inval
id character
Ignore the weird file path, I even just tried to put it on C: \ directly.
There might be another similar Stackoverflow question here: UnicodeEncodeError when using a compile function , but it doesn't look like the file path I'm using uses any non-english characters. I tried a couple of solutions but they didn't work.
Running python 3.4.1 tested earlier in 2.7.x didn't work either. Works fine on linux (Ubuntu).
There is nothing special about the django project as it is just an empty project project.

I had the same problem and found a solution. From what I was looking for, this also happens with Windows 7 and 8.
If you want to know in more detail how I ended up checking the ticket I submitted on the Django forums: Error in manage.py runningerver on Windows (7/8 / 8.1) .
Now, to solve this problem, open this file C: \ Program Files \ Python \ lib \ site-packages \ django \ utils \ autoreload.py (I am using your code as a reference) and add this line of code just before your error ( line 279):
new_environ['PATH'] = os.path.abspath(new_environ['PATH'].replace('\u202a', ''))
Your function should now look like this:
def restart_with_reloader():
while True:
args = [sys.executable] + ['-W%s' % o for o in sys.warnoptions] + sys.argv
if sys.platform == "win32":
args = ['"%s"' % arg for arg in args]
new_environ = os.environ.copy()
new_environ["RUN_MAIN"] = 'true'
new_environ['PATH'] = os.path.abspath(new_environ['PATH'].replace('\u202a', ''))
exit_code = os.spawnve(os.P_WAIT, sys.executable, args, new_environ)
if exit_code != 3:
return exit_code
Now try using manage.py runningerver again. I hope this solves your problem and don't feel lonely.

In my case, it had nothing to PATH
do with what appears to be an environment setting CHROME_RESTART
with some non-english characters. Pulling it out new_environ
did the trick:
def restart_with_reloader():
while True:
args = [sys.executable] + ['-W%s' % o for o in sys.warnoptions] + sys.argv
if sys.platform == "win32":
args = ['"%s"' % arg for arg in args]
new_environ = os.environ.copy()
new_environ["RUN_MAIN"] = 'true'
# This will prevent UnicodeEncodeError
new_environ.pop("CHROME_RESTART", None)
exit_code = os.spawnve(os.P_WAIT, sys.executable, args, new_environ)
if exit_code != 3:
return exit_code

UnicodeEncodeError: 'mbcs' codec can't encode characters in position 0--1:invalid character
I had the same problem on Windows 7 with
$ python manage.py runserver
Just in case anyone has a Cyrillic computer name like mine, this is exactly what is causing the encoding problem. So the solution is to rename your computer using only Latin characters.
