我用 Rei 和 315046509 两位的方法都可以删除了，但那种写法更好呢？

#1 楼 @Rei 还是不行，但是 url 变成这样了http://localhost:3000/events/4?method=delete

#14 楼 @lonre 好的，谢谢了，困扰了好几天，终于解决了

#12 楼 @lonre could not find expected ':' 但是没提示是那个文件，我顺着也没找到，而且 gemrc 文件是从哪里生成的？为什么会出现错误的一行数据？

哇噻，好了可以了，这是什么原因呢？

#8 楼 @lonre

localhost:~ zhangbolei$ cat ~/.gemrc
gem: --no-rdoc --no-ri
gem --no-rdoc --no-ri

结果

localhost:~ zhangbolei$ gem update --system

嗯，这样能看到吗？

这两天一直在做，还是不行 rvm 和 rbenv 都用了，前面都顺利，就是输入 gem 报错 .rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/psych.rb:203:in parse': (<unknown>): could not find expected ':' while scanning a simple key at line 2 column 1 (Psych::SyntaxError) from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/psych.rb:203:inparse_stream' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/psych.rb:151:in parse' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/psych.rb:127:inload' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/rubygems/config_file.rb:253:in load_file' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/rubygems/config_file.rb:191:ininitialize' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/rubygems/gem_runner.rb:78:in new' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/rubygems/gem_runner.rb:78:indo_configuration' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/lib/ruby/1.9.1/rubygems/gem_runner.rb:51:in run' from /Users/zhangbolei/.rbenv/versions/1.9.3-p327/bin/gem:21:in

#3 楼 @lonre 好，我尝试一下，谢谢
