Error in manage.py runningerver with Django 1.8 on windows 8.1

I started learning Django, but when I try to start a local server it doesn't work. When I give the command "runerver" I get this error, hopefully someone can help me fix this problem. I am using windows 8.1, my python version is 3.4.2 and django 1.8

C:\Users\RA\projects\projects django\mysite>python manage.py runserver
Traceback (most recent call last):

I tried adding to autoreload.py

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

      

        
        
        
      

    

leaving the file also

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

      

        
        
        
      

    

but my problem is not solved, i am starting with django and python, this is the first time i use django, help me please!
