從Rails 3升級到Rails 4后，rails 4無法啟動服務器

Question

從導軌3升級到導軌4后，我無法在本地啟動它。 這只是在我的計算機上，因為與我一起工作的其他開發人員沒有這種經歷。 我還必須卸載並再次安裝ruby 2.1.2，因為顯然它是安裝在root下的（現在它在我的用戶名下）。

$ bundle exec rails s
/Users/ohad/.rvm/gems/ruby-2.1.2@project_gemset/gems/railties-4.1.6/lib/rails/commands/server.rb:3:in `require': cannot load such file -- action_dispatch (LoadError)
    from /Users/ohad/.rvm/gems/ruby-2.1.2@project_gemset/gems/railties-4.1.6/lib/rails/commands/server.rb:3:in `<top (required)>'

    from /Users/ohad/.rvm/gems/ruby-2.1.2@project_gemset/gems/railties-4.1.6/lib/rails/commands/commands_tasks.rb:128:in `require_command!'

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

我也無法加載我的控制台

$ bundle exec rails c

Answer 1

檢查權限，可能是您不需要讀取文件-您說最初的ruby是在root用戶下安裝的，所以可能是您沒有完全修復它（例如，這是相同的問題Rails：無需加載此類文件-action_dispatch ）。 嘗試在根目錄下運行rails s ，如果可行，則找到原因。

rvm gemset刪除Fiverr_v2
