有些情况下,我想恢复和卸载以前的所有gem安装.
例如,我需要帮助朋友迁移他们的rails开发机器以使用RVM.由于他们以前使用过系统gem,他在处理多个项目时遇到了许多麻烦. 从本质上讲,他是RVM转换的典型代表.
我怎样才能优雅地卸载他的OSX系统上的所有宝石？
这工作正常,然后突然间没有.我希望我知道为什么.真的卡住了,在网上找不到任何东西.我正在研究一个ObjectiveC项目.我试过用以下方法重置所有内容:
$ sudo gem uninstall ruby
$ sudo gem uninstall cocoapods
然后
$ sudo gem install ruby
$ sudo gem install cocoapods
$ sudo gem update ruby
$ sudo gem update cocoapods
然后我在我的项目目录中运行
$pod install
并得到以下错误.我在所有项目上都得到了这个.
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:110:in `require': cannot load such file -- cocoapods-core (LoadError)

任何想法/线索/答案将非常感激.
