【问题描述】：
我正在尝试创建 cocoa-pod 框架并尝试创建 pod 规范文件，但它给出了以下错误。
/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- rubygems/core_ext/kernel_warn (LoadError)

我尝试了以下命令，但结果相同。
\curl -sSL https://get.rvm.io | bash -s stable
install Ruby with rvm install 2.5.3

请正确格式化问题。
-
macOS 版本？ stackoverflow.com/questions/53856625/… ?
-
我同意：使用 rbenv 安装最新的 Ruby。我发现 Mac OS ruby 2.3.0 几乎没用。
-
用
\curl -sSL https://get.rvm.io | bash -s stable安装RVM；使用rvm install 2.5.3安装 Ruby。 Don'tusesystem Ruby. -
操作系统版本是 macOS-Mojave，@anothermh 我试过给出同样错误的命令。
