Rails 资产预编译只是不工作 [英] Rails Assets Precompile just not working

问题描述

我已将 Rails 应用程序推送到 Heroku 并继续遇到以下问题:

I've pushed a Rails app to Heroku and keep on running into the following problem:

我将保存对我的主要 css.scss 文件(在资产/样式表中)或资产/图像中的图像的更改，推送到 git，将其推送到 heroku，然后重新加载页面，只是为了发现这些资源根本没有加载.

I'll save changes to my main css.scss file (in assets/stylesheets) or to images in assets/images, push to git, push that to heroku, and reload the page, only to find out that these assets haven't been loaded at all.

这也是本地服务器上的一个小问题，但是输入:

This was also a slight problem on the local server, but entering:

rake assets:precompile

并重新加载本地服务器通常有效，而这样做

and reloading the local server usually worked, whereas doing

heroku run rake assets:precompile

然后重新推送什么都不做.我四处寻找信息，但没有发现任何特别有用的信息.

and then re-pushing does nothing. I've fished around for info and haven't found anything particularly helpful.

值得注意的是，在我的 config/application.rb 中(其中一些是上述钓鱼的结果):

Of note, in my config/application.rb (some of these the result of said fishing around):

# Enable the asset pipeline
config.assets.enabled = true

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  # Bundler.require(:default, :assets, Rails.env)
end

在config/environments/production.rb:

# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false

# Compress JavaScripts and CSS
config.assets.compress = true

# Fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true

# Generate digests for assets URLs
config.assets.digest = true

其他可能的兴趣，当我推送到 heroku 时，它说，除其他外，这个:

Of additional possible interest, when I push to heroku, it says, among other things, this:

Preparing app for Rails asset pipeline
       Detected manifest.yml, assuming assets were compiled locally
-----> Rails plugin injection
       Injecting rails_log_stdout
       Injecting rails3_serve_static_assets

和

Installing dependencies using Bundler version 1.3.0.pre.5
Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin --deployment

我在 Rails 3 中学习过，但并不真正了解资产管道与以前版本中可用的内容有何不同，如果我是个白痴并在我的配置文件中放置了重叠和/或矛盾的设置，那么抱歉.

I learned with Rails 3 and don't really know how the assets pipeline differs from what was available in previous version, so sorry if I'm being an idiot and putting overlapping and/or contradictory settings in my config files.

希望得到任何帮助.这让我很头疼.

Would appreciate any help. This has been a headache.

推荐答案

看起来可能是您将本地编译的资产添加到 git 并推送它们，结果 Heroku 没有在推送时编译您的资产.检查以确保您没有将 public/assets 目录添加到 git.

It looks like it could be that you are add your locally compiled assets to git and pushing them and as a result Heroku is not compiling your assets on push. Check to make sure you are not adding the public/assets directory to git.
