bundle exec rake assets：在Dev Environment中预编译失败

Question

这是我的development.rb文件

config.assets.debug = false
config.assets.compile = true
config.assets.enabled = true
config.assets.digest = true
config.assets.raise_runtime_errors = true

当我运行命令bundle exec rake assets:precompile --trace时，我收到以下错误。

Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Execute assets:precompile
rake aborted!
