ruby-on-rails - Gem 环境设置不正确

Question

我正在尝试创建一个新的 Rails 应用程序，但当我尝试“rails new ...”时出现以下错误

/Users/david12/.rvm/rubies/ruby-2.0.0-p598/lib/ruby/site_ruby/2.0.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'railties' (>= 0) among 14 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/david12/.rvm/gems/ruby-2.0.0-p598:/Users/david12/.rvm/gems/ruby-2.0.0-p598@global', execute `gem env` for more information
    from /Users/david12/.rvm/rubies/ruby-2.0.0-p598/lib/ruby/site_ruby/2.0.0/rubygems/dependency.rb:324:in `to_spec'
    from /Users/david12/.rvm/rubies/ruby-2.0.0-p598/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:64:in `gem'
    from /usr/bin/rails:22:in `<main>'

我正在使用 RVM，我相信我已经在安装过程中解决了一些问题。这是我的 gem 环境的输出:

此外，如果它有帮助，这是我的路径:

/Users/david12/.rvm/gems/ruby-2.0.0-p598/bin:/Users/david12/.rvm/gems/ruby-2.0.0-p598@global/bin:/Users/david12/.rvm/rubies/ruby-2.0.0-p598/bin:/Users/david12/.rvm/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

有什么想法可以解决吗？

Answer 1

运行命令

gem install rails

再次。它将下载并安装缺少的依赖项，包括 railties。
