Heroku的/的Ruby-on-Rails的错误:图像不预编译(Heroku / Ruby-on-

2019-07-29 14:27发布

我知道,Heroku上运行耙资产:预编译任务:

-----> Writing config/database.yml to read from DATABASE_URL
-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
-----> Rails plugin injection
       Injecting rails_log_stdout
       Injecting rails3_serve_static_assets
-----> Discovering process types
       Procfile declares types      -> (none)
       Default types for Ruby/Rails -> console, rake, web, worker
-----> Compiled slug size is 17.7MB
-----> Launching... done

我告诉了预编译的production.rb图片

# from: http://stackoverflow.com/questions/8052865/rails-3-1-asset-pipeline-why-my-images-do-not-precompile-for-production
config.assets.precompile += %w[*.png *.jpg *.jpeg *.gif] 

那么,为什么我仍然得到这个500错误?

有趣的是,我有,显示就好了其它的页面图像。 不知道为什么有些图片是行不通的,但有些人会...

Answer 1:

首先,要确保你有这一套,以及:

config.assets.initialize_on_precompile = false

如果不工作,这是值得尝试建立蛞蝓之前手动运行预编译任务; 我认为有这样做的方式,当细微的差别:

RAILS_ENV=production bundle exec rake assets:precompile

最后,它不是一个解决方案,但如果一切都失败了,暂时的解决办法是设置

config.assets.compile = true


Answer 2:

确保你把你的图像

app/assets/images

不是

public/assets

直。

然后运行rake assets:precompile ,看看它是否提高。 它可以得到一个有点混乱。
