在推送到heroku之前无法进行资产预编译

Question

我需要让它让我的jQuery在Heroku上运行。

这是我的控制台：

    $ rake assets:precompile
    c:/Ruby192/bin/ruby.exe c:/Ruby192/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
  rake aborted!
  Access denied for user 'root'@'localhost' (using password: NO)
  Tasks: TOP => environment
  (See full trace by running task with --trace)
   rake aborted!
  Command failed with status (1): [c:/Ruby192/bin/ruby.exe c:/Ruby192/bin/rak...]
  Tasks: TOP => assets:precompile
  (See full trace by running task with --trace)

当我尝试运行时：

     $ assets:precompile
     sh: assets:precompile: command not found

编辑： 我还将此行添加到application.rb：

      config.assets.initialize_on_precompile = false

您提到了错误的mysql用户名和密码。一些需要数据库访问资产的宝石：预编译。
