Rubygems 2.0.14在使用时不是线程安全的bunder安装消息 - RUBYGEMS VERSION：2.4.5.1 [英] Rubygems 2.0.14 is not threadsafe bunder install message when using - RUBYGEMS VERSION: 2.4.5.1

问题描述

  Rubygems 2.0.14不是线程安全的，所以你的宝石将会一次安装一个。升级到Rubygems 2.1.0或更高版本以启用并行gem安装。 
  

这很奇怪，因为在我的RubyGems环境中它说我的RubyGems版本是2.4.5.1（见下文）

 〜/ w / Rafftopia❯❯❯gem env 
 RubyGems环境：
  -  RUBYGEMS版本： 2.4.5.1 
  -  RUBY VERSION：2.2.5（2016-04-26 patchlevel 319）[x86_64-darwin14] 
  - 安装目录：/Users/phillipjones/.gem/ruby/2.2.5 
  -  RUBY EXECUTABLE：/Users/phillipjones/.rubies/ruby-2.2.5/bin/ruby 
  - 可执行目录：/Users/phillipjones/.gem/ruby/2.2.5/bin 
  -  SPEC CACHE DIRECTORY：/Users/phillipjones/.gem/specs 
  -  SYSTEM CONFIGURATION DIRECTORY：/Users/phillipjones/.rubies/ruby-2.2.5/etc 
  -  RUBYGEMS平台：
  -  ruby​​ 
  -  x86_64-darwin-14 
  

解决方案

run sudo gem update --system

参考： h ttp：//blog.rubygems.org/2017/03/16/2.6.11-released.html

When running the bundle install I get the following message:

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.

Which is strange because in my RubyGems Environment it says my RubyGems Version is: 2.4.5.1 (see below)
