Django manage.py 命令挂起

Question

以前正常工作的东西，刚刚放弃了我。当使用如下任何类型的 manage.py 命令时，我看到 Performing system checks...

python manage.py runserver

或

python manage.py makemigrations

挂起大约 30-60 秒后，我得到：

System check identified no issues (0 silenced).

挂啊挂啊挂啊……大约6分钟后，我又看到正常了Quit the server with CONTROL-C 为了调试这个问题，我什至尝试注释掉我的应用程序和中间件，以及关闭我的 PY 上的其他应用程序并执行重启，仍然没有任何变化。我还需要看什么？这似乎太长了。

Answer 1

我自己找到了问题所在。它与我的 settings.py 文件有关：

ADMINS = (
  ('My name', 'myemail@domain.com'),
)

注释掉此代码使 manage.py 命令的速度再次恢复正常。我不太确定为什么除了通知尝试 send/communicate 使用此地址之外的原因，并且由于我在代理后面，所以该过程花费了几分钟的时间。也许有人可以为此提供更准确的原因。
