and i was bored with it .and when i run a py in captcha,it says like this :

    C:\Windows\system32\cmd.exe /c python.exe fields.py

Answer 1

Please look into the below URL. From 10th conversation same problem is discussed.

https://github.com/mbi/django-simple-captcha/issues/41

Possible solutions provided in above link -

• Do you also have this library installed in both global as well as virtual environments?

  if Yes then uninstall the one which is not required.

• Did you redefined "CAPTCHA_OUTPUT_FORMAT" in your settings?

  if yes then test after commenting that line.

Answer 2

this is because i've delete the globle var='DJANGO_SETTINGS_MODULE' in my windows ,which i think is of not a big use. and i reset it in windows. and the test finally says OK,meaning the 2 warnings above not very important. but after i fix the revalidation in formwizard and single validation in captcha, tests shows plenty errors ,and i ignoresit. this question annoies me three or more days ,whick had to be writen for remember.
