如何让Ruby在优胜美地上工作

升级到约塞米蒂后，我在使用Ruby应用程序时遇到了麻烦。我以为它与livereload应用程序本身有关，但我在其他web开发应用程序上也遇到了同样的错误。我在谷歌上搜索没有用，我对Ruby不够精通，无法调试自己

这是输出，如果有人能解释的话

我使用ruby安装来获得长期的ruby快乐：

下面是我在osx中设置ruby环境的步骤

brew update
brew install ruby-install
brew install chruby
ruby-install ruby

最后一行需要一些时间，为您安装一个全新的ruby 2.1.3

现在，将以下内容添加到~/.bashrc或~/.zshrc文件的末尾：

source /usr/local/opt/chruby/share/chruby/chruby.sh

就这样

这将在/Users/bibstha/.rubies/ruby-2.1.3/中安装ruby。由于这是您的主文件夹，因此在安装gems时您不会遇到任何权限问题，也不会使系统混乱。

使用：

这是一个权限错误，这是使用OSX系统Ruby时的典型错误。。。使用rvm、rbenv或chruby安装ruby，而不是使用Apple版本。您好，谢谢，我需要告诉系统使用哪个版本吗？我应该删除旧版本吗？chruby负责切换不同的ruby版本。默认情况下，您的系统首选ruby。但是，如果您在项目中放入一个包含2.1.3内容的file.ruby版本，它将自动切换到此版本。同时执行chruby ruby将切换到新安装的版本。
