Question

我正在尝试将我的应用推送到Heroku。

一切正常，直到最后一个命令git push heroku master

工作的结束是：

以消息Precompiling assets failed

结束

我猜它正在寻找我的资产（css或javascript）中缺少的目录。但我不知道哪个目录。

非常感谢任何帮助。

修改

我的文件cable.js看起来像这样：

//= require action_cable
//= require_self
//= require_tree ./channels
(function() {
  this.App || (this.App = {});
  App.cable = ActionCable.createConsumer();
}).call(this);

我是否添加了//= require_tree或者我是否对所有内容进行了评论，并没有改变任何内容。

Answer 1

你的cable.js文件的第6行是什么样的？

您使用的是Action Cable吗？

在app/assests/javascripts/cable.js文件中，//= require_tree语句后面必须跟一个目录，如下所示：

//= require_tree ./channels

然后，您的频道文件位于app/assets/javascripts/channels

目录中

如果您没有使用Action Cable，那么只需对所有内容进行评论，您的推送就应该成功。

编辑：

您应该删除cable.js文件。并注释掉app/channels/application_cable/channel.rb和app/channels/application_cable/connection.rb

中的所有代码

这使我可以将Rails 5项目推送到Heroku而不会出现资产错误。

Answer 2

我认为你不应该删除或评论某些内容。但是Heroku需要一个空的./channels目录，你现在还没有。只需添加一个空文件，例如.keep到你的./channels目录，提交它并推送到Heroku。

请参阅： require_tree argument must be a directory in a Rails 5 upgraded app

heroku push被拒绝：require_tree参数必须是一个目录
