[Django]-Error in manage.py runserver with Django on windows 8.1

βœ…

I was having the same issue, and I found the solution. From what I searched it also happens with
Windows 7 & 8.

If you want to know with more detail how I solved it check
the ticket I filed in Django’s forums: Error in manage.py runserver on Windows (7 / 8 / 8.1).

Now to solve the error open this file C:\Program Files\Python\lib\site-packages\django\utils\autoreload.py (I’m using your code as 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 now should 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 again manage.py runserver. I hope this solves your problem and
don’t feel you’re alone.

In my case it had nothing to do with PATH, there seem to be CHROME_RESTART environment setting with some non-english characters. Poping it from 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

I tried this

new_environ['PATH'] = os.path.abspath(new_environ['PATH'].replace('\u202a', ''))

but it did not work.

And my solution is

new_environ['PATH'] = os.path.abspath(new_environ['PATH'].encode('ascii', 'replace'))

Hope it will help you!

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 if someone has cyrillic computer name like I had, it’s exactly the thing causing your encoding problem. So the solution is to rename your computer using latin alphabet symbols only.

I had the same problem.
The reason was non latin characters in an environment variables entry.
In my case it was cyrilic name of some folder, while my windows was originally english version.
So it had a conflict. After removing it – everything worked ok.
