The simple solution was to add one simple line to my application.rb
简单的解决方案是在我的 application.rb 中添加一个简单的行
config.assets.initialize_on_precompile = false
And everything works.
一切正常。

This should work: rake assets:precompile RAILS_ENV=development
这应该有效：rake assets:precompile RAILS_ENV=development
It tries to load up your production environment, when your database.yml doesn't include it.
当您的 database.yml 不包含它时，它会尝试加载您的生产环境。

Heroku will overwrite your database.yml with its own version, regardless of what you put in there. However, your rake task running in the Production environment requires a variable, so give it a dummy one.
Heroku 会用它自己的版本覆盖你的 database.yml，不管你在那里放了什么。但是，在生产环境中运行的 rake 任务需要一个变量，所以给它一个虚拟变量。
As noted above, you can also add 'config.assets.initialize_on_precompile = false' to your production.rb. If set, Heroku requires it be set to 'false'.
如上所述，您还可以将“config.assets.initialize_on_precompile = false”添加到您的 production.rb。如果设置，Heroku 要求将其设置为“false”。

This solution stopped working with rails 4, here is the updated one: just pass a dummy database as mentioned in this article:
此解决方案停止使用 rails 4，这是更新的解决方案：只需传递本文中提到的虚拟数据库：

The command is: bundle exec rake RAILS_ENV=production DATABASE_URL=postgresql://user:[email protected]/dbname assets:precompile
命令为：bundle exec rake RAILS_ENV=production DATABASE_URL=postgresql://user:[email protected]/dbname assets:precompile

Make sure you have some dummyproductionentry in your local config/database.ymlfile
确保您的本地文件中有一些虚拟production条目config/database.yml
production:
<<: *default
database: your_local_database_name
I've come across the same error in 2016 with Rails 4.2.6 and Capistrano 3.4. We were precompiling the assets during the deploy script just before uploading them together with the code, but rake assets:precompile needs some production entry, even if it's just a dummy one.

我在 2016 年使用 Rails 4.2.6 和 Capistrano 3.4 遇到了同样的错误。在将资产与代码一起上传之前，我们在部署脚本期间对资产进行了预编译，但是 rake assets:precompile 需要一些生产条目，即使它只是一个虚拟条目。来源：https: //github.com/TalkingQuickly/capistrano-3-rails-template/issues/12

What worked for me was this:
对我有用的是：
rake assets:precompile RAILS_ENV=production
rake assets:precompile RAILS_ENV=production
Access your server via ssh and type that command in, it should do the trick.
通过 ssh 访问您的服务器并输入该命令，它应该可以解决问题。
