在Sierra OS上添加gem

Question

在升級到OS X Sierra之后，我嘗試更新並運行現有的Ruby gem。

> sudo gem update --system

> Password: *enters password*

> Updating rubygems-update...

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

> Operation not permitted - /usr/bin/update_rubygems

無論我直接從RubyGems執行還是從Github克隆並退出，都會發生這種情況。 使用sudo運行命令還會返回一條錯誤消息，提示我缺少權限。

我嘗試了sudo rubygems_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/Cellar/ruby/2.4.0/lib/ruby/2.4.0/rubygems/core_ext/kernel_gem.rb:65:in `gem'
    from /usr/local/bin/update_rubygems:22:in `<main>'

我剛剛執行了gem env ，我的終端返回了以下內容：

也許安裝rvm是最好的選擇。 我通常避免使用OS X隨附的默認紅寶石。

話雖如此，我認為Sierra具有需要禁用的新安全性，您可以在此處閱讀有關內容： 禁用Mac OS SIP
