Ruby Rails 更新 rubygems 后出现错误：“找不到宝石 [] >= 0”

Question

我刚刚在 Rails 上安装了 Ruby，在尝试遵循 this tutorial 时，我一直运行警告我更新 rubygems，然后运行 gem pristine --all。我使用 sudo gem install rubygems-update 更新并尝试运行ning gem pristine --all，这导致了以下错误：

ERROR:  While executing gem ... (Gem::Exception)
    Failed to find gems [] >= 0

我也在博客应用程序上尝试运行ning bin/rails server，但出现以下错误：

/usr/local/lib/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)
    from /usr/local/lib/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require'
    from /home/mariana/Documents/RD-anagram/rails-test/blog/bin/spring:8:in `<top (required)>'
    from bin/rails:3:in `load'
    from bin/rails:3:in `<main>'

我也不能运行 rails --version，因为我得到这个错误：

/usr/local/lib/site_ruby/1.9.1/rubygems/dependency.rb:319:in `to_specs': Could not find 'railties' (>= 0) among 0 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/home/mariana/.gem/ruby/1.9.1:/usr/lib/ruby/gems/1.9.1', execute `gem env` for more information
    from /usr/local/lib/site_ruby/1.9.1/rubygems/dependency.rb:328:in `to_spec'
    from /usr/local/lib/site_ruby/1.9.1/rubygems/core_ext/kernel_gem.rb:65:in `gem'
    from /usr/local/bin/rails:22:in `<main>'

有谁知道如何解决这个问题？我是不是做错了什么？

看来您缺少捆绑器 gem。

做：-

gem install rails    
[sudo] gem install bundler
bundle install
gem install railties

如果上面的代码不起作用，你可以做一个 rvm implode 重新安装 rvm。请注意，该命令递归删除所有 rvm 环境。
