遇到此错误时，我正在尝试为特定存储库设置本地环境。
An error occurred while installing mini_racer (0.1.15), and Bundler cannot continue.
Make sure that `gem install mini_racer -v '0.1.15' --source 'https://rubygems.org/'` succeeds before bundling.
我的本地计算机是macOS X（Mojave）。我安装了ruby 2.1.5，更新了捆绑程序并运行bundle install
这是详细的错误：-

我根据以下相关链接研究了该问题：https://github.com/discourse/mini_racer/issues/104
基于几个堆栈溢出的帖子，我卸载了libv8 gem，然后尝试进行gem install mini_racer。不幸的是，它没有用
即使重新安装红宝石也没有任何效果。我该如何解决这个问题？
此堆栈溢出帖子是针对与我的similar post类似的问题，它说设置不同的版本可能是最好的，但不确定是Ruby（2.1.5）的最佳版本，并且导轨（3.2.xx）
