运行bundle install时,我收到以下消息:

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.

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)

我刚刚升级到webpack 4.我使用css模块.

错误:

我使用Chruby ruby​​版本控件设置我的ruby默认值,但是当我尝试使用我的系统版本时,它会使用我的系统版本.我该如何解决？
