我在谷歌上到处搜索并尽我所能解决这个错误，但一切都是徒劳的。当我在环境中运行pip freeze 时，它说我已经安装了django Django==3.2 当我尝试pip install django 它说requirement already satisfied 我也尝试在环境之外安装它，但同样的requirement already satisfied 我的WSGI.py 文件位于正确的地方。此外，这是我的文件的屏幕截图。这是我的 wsgi.py

这是邮递员的错误：没有邮递员，它给了我同样的错误。任何帮助将不胜感激非常感谢。

【问题讨论】：

你检查过你是否安装了 Django 版本吗？ python3 -m django --version
pip 可能指向其他一些 python 安装。所以，你可能想运行python3 -m pip install django
如果您使用的是 IDE，您是否检查过它是否在自己的虚拟环境中运行？
EMAIL_BACKEND = ' django.core.mail.backends.smtp.EmailBackend' 注意到 space 就在django.core 之前（' 之后）？这就是你的错误的原因。删除空间因此它应该是EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
是的@schuhesindbequemer 它说 3.2 。是的，它正在环境中运行。我试过python -m pip install django1 它说要求已经满足了。

标签： python python-3.x django django-rest-framework pip

【解决方案1】：

@AbdulAziz 所说的错误出现在额外的空间中

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' 注意到 django.core 之前的空格（' 之后）？这就是你的错误的原因。删除空格，因此它应该是 EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' -
