ModuleNotFoundError：即使在重新检查我已安装该软件包后，也没有名为“channels”的模块

Question

我的软件包有问题，我已经使用 pip installchannels 命令安装了 djangochannels（只是通道），当我尝试运行服务器命令时，我刚刚收到一个错误，说模块未找到，但当我运行命令时

pip list | grep channels

安装了两个模块

channels                            2.1.6
channels-redis                      2.3.3

我不知道错误背后的原因 有人可以帮我弄清楚我是否做错了什么

我已将它们添加到 settings.py 的已安装应用程序部分中

Answer 1

同样的事情也发生在我身上。我只是执行

pip install channels

就成功了。

Answer 2

您可能忘记在 settings.py INSTALLED_APPS 中写入逗号。
