RailsTutorial：找不到 diff-lcs-1.1.3
http://ruby.railstutorial.org/chapters/static-pages#top
我正在玩那个教程，执行时：
rails generate rspec:install
我得到这个：
Could not find diff-lcs-1.1.3 in any of the sources
Run 'bundle install' to install missing gems.
运行bundle show时：
...
* builder (3.0.0)
* bundler (1.1.rc)
* diff-lcs (1.1.3)
* erubis (2.7.0)
* hike (1.2.1)
...
并且我确保它已安装...... 我可以在系统等中找到它......
有什么想法吗？从来没有真正研究过 ruby，所以这可能就是我失败的原因，哈哈

i was playing around with that tutorial and when executing:
rails generate rspec:install
i get this:
Could not find diff-lcs-1.1.3 in any of the sources
Run 'bundle install' to install missing gems.
when running bundle show:
...
* builder (3.0.0)
* bundler (1.1.rc)
* diff-lcs (1.1.3)
* erubis (2.7.0)
* hike (1.2.1)
...
and i made sure its installed....
i can find it in the system etc....
any ideas? never really looked into ruby so that might be why i am failing already, haha

您应该首先运行
bundle install，如上面错误消息中所述，首先运行
bundle install或bundle install --without production，然后运行
rails g rspec:install我强烈建议您检查：
http://ruby.railstutorial.org/chapters/static-pages#code-gemfile_rspec
并运行
bundle install。我也想知道你是否安装了RVM成功。
如果你安装gems失败，我想你应该再看一遍前面的部分。
You should run
bundle installfirst as mentioned in the error message aboveRun
bundle installorbundle install --without productionfirstand then run
rails g rspec:installI highly recommend you check:
http://ruby.railstutorial.org/chapters/static-pages#code-gemfile_rspec
and run
bundle install.I also wonder if you installed RVM successfully.
If you fail to install gems, I think you should go over the previous part again.
