Question

我最近关注了多个博客，彻底消灭了rvm，rails，然后重新安装了ruby 2.3.0和rails 5.制作和app使用它没有问题。但是当我在我的机器中打开一个新的终端窗口时，它根本没有识别出轨道，好像它只安装在那个特定的终端上。

所以我刚刚完成了我在单一终端的工作。现在，当我重新启动笔记本电脑时，我无法运行相同的应用程序。我不想再重新安装所有内容，因为我确信这是一个小配置问题。为什么会这样？

我现在收到的错误消息：

/Users/sahil/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'railties' (>= 0.a) among 30 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/sahil/.rvm/gems/ruby-2.3.1:/Users/sahil/.rvm/gems/ruby-2.3.1@global', execute `gem env` for more information

    from /Users/sahil/.rbenv/versions/2.3.1/bin/rails:22:in `<main>'

我已经看过其他类似的问题，他们要求重新安装所有我不想做的事情，因为它在安装后工作但在系统重启时无效。

现在我在一个终端中执行了gem install rails并且应用程序再次运行，但是如果我尝试打开一个新终端并给出相同的命令rails s，它会给我这个错误，

你提到你重新安装了ruby 2.3.0和Rails 5.但是似乎rbenv正试图用ruby 2.3.1加载你的项目。你应该切换到ruby 2.3.0。我想你应该可以做到：rbenv local 2.3.0。为了避免再次发生这种情况，您应该向项目根目录添加.ruby-version点文件，并且只在文件中添加2.3.0。
