推到heroku:没有名为“通道”的模块

Question

当我在INSTALLED_APPS中添加“通道”时，我将面临这个错误

到目前为止，我尝试过什么：

我禁用了收集器，它可以将代码推送给heroku，但是服务器崩溃了。

卸载通道并重新安装

有人能给我一些提示吗谢谢。

我也有过同样的问题。这个问题是因为我使用了django-channels (还有django_channels)而不是channels )。

django通道的正确包实际上是通道。

所以就这么做：

1. 列出所有已安装的带有通道的包

pip列表\ grep通道

产出：

频道(1.1.6) 频道-api (0.4.0) django-频道(0.7.0)

1. 通过使用pip卸载包-名称: ex: pip卸载django-通道来卸载其中的每个通道(偶数通道)
2. 只重新安装通道(女巫称为，而不是‘django-’或'django_channels')包，使用：

pip安装通道

1. 使用以下方法创建requirements.txt：

pip冻结> requirements.txt
