Django版本2.1.5 频道版本2.1.6 Ubuntu 18.0.4

当我在pyCharm中运行项目时，它说：

Unhandled exception in thread started by <function check_errors.

ModuleNotFoundError: No module named 'channels'

已安装模块

(venv) mercer@mercerPC:~/Documents/comet$ pip list | grep channels
channels 2.1.6

这是已安装的应用程序：

INSTALLED_APPS = [
    'channels',
    'chat',
    'accounts',
    'events',

    ...

]

我还创建了路由文件，并在ASGI_APPLICATION = 'mysite.routing.application'中添加了settings.py

我可以在您的堆栈跟踪中看到python环境称为：venv_linux，您在另一个名为pip list | grep channels的环境中执行venv。

那是你的问题。

NoModuleName'通道'，但是我已经安装了它。 Django的
