I just tries to start django project on win7(x64), but i faced with following issue: 

$ python manage.py runserver Performing system checks... System check identified no issues (0 silenced). March 24, 2018 - 14:24:08 Django version 1.11.3, using settings 'superlists.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CTRL-BREAK.

My computer has an ASCII name, so I even not realized, what happens. Did all these things on another win7 and everything was ok. Maybe someone can help with?

UPD. My problem was due to the changed 'hosts' file - there are a lot of disabled addresses. Thanks all for the answers.

  • There is a warning in trace "You have 13 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions. Run 'python manage.py migrate' to apply them.". Try to run 'python manage.py migrate' Commented Mar 24, 2018 at 11:16
  • thank u for answer, but it didn't help. I've edit my question after migration. Commented Mar 24, 2018 at 11:25
  • Your error is "UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbb in position 14: invalid start byte". look to this stackoverflow.com/questions/22216076/… Commented Mar 24, 2018 at 13:02
  • Perhaps there are other names mapped to 127.0.0.1 in your hosts file that do not contain ASCII characters. Could you post your C:\Windows\System32\drivers\etc\hosts file and also the name of your computer. Commented Mar 24, 2018 at 14:14
  • Will, thank you.I have modified host file, and disable a lot of ms addresses. So I think this is a reason of my problem. Name of computer is buk. Commented Mar 25, 2018 at 16:03

use python3, if you use python2.x many letters like accents or others, they cause abnormal crashes
