安装 cocoapods 时出错

Question

我正在尝试安装最新的 CocoaPods（当前为 1.0.1），但它显示以下错误。

$ sudo gem install cocoapods
Password:
Fetching: i18n-0.7.0.gem (100%)

安装指南说

[...] it will be installable with the default Ruby available on macOS. You can use a Ruby Version manager, however we recommend that you use the standard Ruby available on macOS unless you know what you're doing.

ruby 不是我的首选语言，所以任何人都可以帮助我，我如何安装 cocoapods gem?

OSX 版本：OS X El Capitan 10.11.5

Answer 1

首先安装旧版本的'activesupport'（与ruby 2.0 和cocoapods 兼容），然后安装cocoapods。 sudo gem install activesupport -v 4.2.6

Answer 2

请从下面安装最新版本的 Ruby 和 RVM（Ruby 版本管理器）link：（步骤在 this link 中提供)

然后在终端中运行 "sudo gem install cocoapods"。
