Question

我的应用程序在开发中很花哨，但昨天我尝试将它移动到我的生产服务器上，经过一些权限和路径的工作之后，我得到了它的工作。但似乎我无法加载JS资产，而图像和CSS工作正常。起初我以为是bootstrap js文件让我的生活变得错了，但删除它只会让我在下一个JS资产上出错。

Answer 1

我为Heroku执行此步骤你好在部署文件

之前做了以下更改

------ ----- enviorment.rb

::ActiveSupport::Deprecation.silenced = true

------ ------- Production.rb

config.assets.compile = ['*.js', '*.css']

config.active_support.deprecation = :silence

------- ------- application.rb中

config.assets.enabled = true
config.assets.initialize_on_precompile = false

Answer 2

尝试更改

  config.serve_static_assets = false

到

  config.serve_static_assets = true

Answer 3

我的应用在将其推送到heroku时遇到了问题。我曾经使用过twitter-bootstrap，在预编译资产时出现了一些错误。所以我切换到手动编译而不是自动预编译。为此，我做了以下事情：

我在config / application.rb中将initialize_on_precompile设置为false，如下所示：

config.assets.initialize_on_precompile = false

然后我通过运行手动完成：

bundle exec rake assets:precompile RAILS_ENV=production

最后它起作用了......

除非您使用任何预定义的前端框架，否则这可能不是您要寻找的解决方案。

Answer 4

检查你的application.js文件我添加了一些代码来做一个java脚本代码，添加到一些funk奇怪的文件。问题是我错过了一些必须被注释掉的代码的“/”:(愚蠢的我花了很长时间

bundle exec rake assets:precompile RAILS_ENV=production

向我展示了要查看的文件和行，我在sublime中打开了该文件。我希望这有点花了我5天才能找到这个该死的错误smh
