为什么掠夺资产:在开发中进行预编译会引起问题，但在我的生产环境中却不会 [英] Why does rake assets:precompile in development cause problems but not in my production environement

问题描述

我已将我在Heroku上的应用程序升级到雪松堆栈，以便资产管道正常工作.通过选择在本地编译资产，我遵循了 heroku的文档中给出的说明.

I have upgraded my app on heroku to a cedar stack so that the asset pipeline works. I have followed the instructions given in heroku's docs by choosing to compile assets locally.

这已创建目录public/assets.生产中的所有内容都能完美运行(css，js，没有问题).回到我的开发环境似乎导致js无法正常运行.

This has created a directory public/assets. Everything in production works perfectly(css, js, with no problems). Going back to my development environment seems to cause the js to not function properly.

在 environments/production.rb

config.serve_static_assets = false
config.assets.compress = true
config.assets.compile = true
config.assets.digest = true

在 environments/development.rb

config.assets.compress = false
config.assets.debug = true
config.assets.compile = true

我已经检查了源页面，并且所有文件都正确加载，没有重复的条目.我已经阅读了一些关于是否在本地还是在生产中编译资产的问题，但是似乎没有一个问题.恢复我的开发javascript代码还有其他遗漏吗?这是要遵循的正确步骤吗?谢谢

I have checked the source page and all files get loaded correctly with no duplicate entries. I have read some SO questions about whether to compile assets locally or in production but none of them seem to help. Is there something else that i am missing to restore my development javascript code and is this the correct procedure to follow? Thank you

推荐答案

好，我似乎已经解决了.

Ok i seem to have solved it.

在environment/development.rb中，更改此行

config.assets.debug = true

对此

config.assets.debug = false

不确定该方法为何有效，但请阅读Rails指南并引用:

Not sure why this works but from reading the rails guides and quote:

当调试模式关闭时，Sprockets会串联并在所有文件上运行必要的预处理器.在调试模式关闭的情况下，上面的清单会生成:"

"When debug mode is off, Sprockets concatenates and runs the necessary preprocessors on all files. With debug mode turned off the manifest above would generate instead:"

<script src="/assets/application.js" type="text/javascript"></script>

希望这可以帮助遇到类似问题的人.
