rails admin找不到rails_admin.scss.erb

Question

rails admin throw error然后我会尝试输入/ admin

Errno::ENOENT in RailsAdmin::Main#dashboard 
No such file or directory @ realpath_rec - /home/acer-as/work/vendor
  (in /home/acer-as/.rvm/gems/ruby-2.1.1@myproject/bundler/gems/rails_admin-f420baa7acad/app/assets/stylesheets/rails_admin/rails_admin.scss.erb)

我平时安装了一切，无法理解它有什么问题 rails 4.1.0（也尝试4.1.5） 红宝石2.1.1 P.S fi将检查此路径：/home/acer-as/.rvm/gems/ruby-2.1.1@myproject/bundler/gems/rails_admin-f420baa7acad/app/assets/stylesheets/rails_admin/rails_admin.scss.erb  文件在正确的位置，所以它不会错过
