我添加了 gem 'pry-rails'，当我运行 rails 控制台时，我收到以下错误：

Loading development environment (Rails 3.2.6)

我的宝石文件：

...
group :development do
  gem 'rack-mini-profiler'
  gem 'pry-rails'
end
...
gem 'ruby-readability', require: 'readability'
...

当我更改为时gem 'ruby-readability', require: 'readability'，gem 'ruby-readability', :require => 'readability'我收到下一个错误：

根据此文档，您应该指定如下

 gem "ruby-readability", :require => 'readability'

您在第二种方法中已经完成了。您收到此错误

 Your Ruby version is 1.8.7, but your Gemfile specified 1.9.3

因为从 Bundler 1.2 你有这个非常有用的新特性validate your Ruby version所以如果你想使用 ruby​​ 1.8.7 在你的 Gemfile 顶部指定

ruby '1.8.7'

问题是因为我在我的pryrc:require 'pry-vterm_aliases'从我的pryrc问题中删除后解决了

你的环境怎么rvm info说？怎么样ruby -v？最后，which ruby? 我怀疑你没有运行正确的红宝石，也许你的路上还有另一个。
