ruby - 为什么无法启动Rails呢？

Question

我之前也安装了meteor，启动地址是localhost:3000，Rails启动后地址也是localhost:3000，,是因为地址冲突了吗？该怎么解决呢？

Answer 1

method_missing: ‘undefined method ‘this’’ Find it yourself in your error log

Answer 2

This should be a bug in the gem, refer to https://github.com/rubygems/rubygems/issues/1420

There are two solutions. The first is to manually add this method. Of course, this is not recommended.
The second one is to upgrade the gem, http://gems.ruby-china.org/ There is a method to upgrade the gem, but it seems to have to bypass the wall
