推送到heroku：没有名为“频道”的模块

Question

当我将“频道”添加到 INSTALLED_APPS 时遇到此错误

remote:
remote:        https://devcenter.heroku.com/articles/django-assets
remote:  !     Push rejected, failed to compile Python app.
remote:

到目前为止我尝试了什么：

我禁用了 collectstatic，它能够将代码推送到 heroku 但服务器崩溃了

卸载频道并重新安装

谁能给我一些建议，谢谢。

我有同样的问题。问题是由于我使用 django-channels（还有 django_channels）而不是 channels。

django 频道的正确包实际上是 channels。

那么就这样做吧：

1. 列出所有已安装的软件包，名称中包含 channels

点列表 | grep 频道

输出：

频道 (1.1.6)

channels-api (0.4.0)

django 频道 (0.7.0)

1. 使用 pip uninstall package-name 卸载每个（甚至频道）： 例如：pip 卸载 django-channels
2. 仅使用以下方式重新安装频道（witch 称为 channels 而不是 'django-channels' 或 'django_channels'）包：

pip 安装渠道

4. 使用以下命令创建 requirements.txt：

pip freeze > requirements.txt
