指定 Rails 版本 [英] Specifying Rails Version

问题描述

我决定升级到 Ruby 2.0.0 和 Rails 4.0.0.我正在尝试使用以下行将这些设置为我的默认程序:

I decided to upgrade to Ruby 2.0.0 and Rails 4.0.0. I'm trying to set these as my default programs, by using this line:

rvm use 2.0.0@rails-4.0.0 --default

我收到错误

Failed to load /Users/michaeldunnegan/.gemrc because it doesn't contain valid YAML hash

我的 .gemrc 文件是空白的.我不知道该怎么办.我根本找不到任何参考资料.

My .gemrc file is blank. I don't know what to do. I can't find any references at all.

推荐答案

很可能不是空的，有很多 UTF-8 字符编辑器不会显示给你，去掉继续之前的文件:

most likely it is not empty, there is a lot of UTF-8 characters that editor will not show you, just remove the file before continuing:

rm -f /Users/michaeldunnegan/.gemrc
