django简单captcha一直说“无效的captcha”

Question

我遵循了docs给出的步骤，首先，它工作得很好，但是，我不知道有什么不对的地方，它制造了一个invalid Captcha。我运行manage.py test captcha，它是这样写的：

C:\Windows\system32\cmd.exe /c python.exe manage.py test captcha
Creating test database for alias 'default'...
.......Internal Server Error: /test/

我搜索了一段时间，但没有找到任何结果。CAPTCHA_OUTPUT_FORMAT和%(hidden_field)s可能有问题，但我不知道如何解决？

当我在captcha上运行一个py时，我对它感到厌烦，它说：

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

在那里我继续找不到复制的卡普查，有什么帮助吗？

Answer 1

请查阅以下网址。从第十次对话中，我们讨论了同样的问题。

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

在上述链接中提供的可能解决方案-

• 您是否在全局环境和虚拟环境中都安装了这个库？ 如果是，则卸载不需要的。
• 您在设置中重新定义了"CAPTCHA_OUTPUT_FORMAT“吗？ 如果是，那么在注释该行之后进行测试。

Answer 2

这是因为我已经删除了窗口中的globle var='DJANGO_SETTINGS_MODULE'，我认为这并没有多大用处。我把它重新设置在窗户上。测试最后说到了OK，这意味着上面的两个警告并不重要。但是在我修复了revalidation in formwizard and single validation in captcha之后，测试就会显示出大量的错误，并且我会修改它。这个问题使我烦恼了三天或更长时间，为了记住，我不得不写上这个问题。
