RubyGems的2.0.14是不是線程安全的bunder使用時安裝消息 - RubyGems的版本：2.4.5.1

Question

當運行安裝包我得到以下信息：

Rubygems 2.0.14 is not threadsafe, so your gems will be installed one at a time. Upgrade to Rubygems 2.1.0 or higher to enable parallel gem installation. 

這很奇怪，因爲我在RubyGems的環境，它說我RubyGems的版本是：2.4.5.1（見下文）

~/w/Rafftopia ❯❯❯ gem env
