Ruby 在Sierra OS上添加宝石

在升级到OS X Sierra之后，我尝试过更新和运行现有的Ruby gems

> sudo gem update --system

> Password: *enters password*

> Updating rubygems-update...

> ERROR:  While executing gem ... (Errno::EPERM)

> Operation not permitted - /usr/bin/update_rubygems

无论我是直接从RubyGems执行，还是从Github克隆并下拉，都会发生这种情况。使用sudo运行命令也会返回一个错误，表示我缺少权限

我尝试了

sudo rubygems\u update

：

/usr/local/Cellar/ruby/2.4.0/lib/ruby/2.4.0/rubygems/dependency.rb:308:in `to_specs': Could not find 'rubygems-update' (>= 0.a) among 7 total gem(s) (Gem::MissingSpecError)
Checked in 'GEM_PATH=/Users/Angelfirenze/.gem/ruby/2.4.0:/usr/local/lib/ruby/gems/2.4.0:/usr/local/Cellar/ruby/2.4.0/lib/ruby/gems/2.4.0', execute `gem env` for more information
    from /usr/local/Cellar/ruby/2.4.0/lib/ruby/2.4.0/rubygems/dependency.rb:320:in `to_spec'

    from /usr/local/bin/update_rubygems:22:in `<main>'

也许安装是最好的选择。我通常避免使用OSX附带的默认ruby

话虽如此，我认为Sierra的新安全功能需要禁用，您可以在这里阅读：

我将它们分成了不同的句子，而不是简单地复制和粘贴。现在读起来更好了吗？

sudo update\u rubygems

？我已经安装了rvm，但我会尝试运行更新；谢谢你通知我塞拉的愚蠢行为。如果我更暴躁的话，我会回到El Capitan，但我想我已经换了太多了。我在Sierra上，但我从不在任何gem命令中使用

sudo

，无论是系统Ruby还是我通过

rbenv

，如果你不使用

sudo

，会发生什么？
