【问题描述】：
当我遇到此错误时，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.
我的本地机器是 macOS X (Mojave)。我安装了 ruby 2.1.5，更新了 bundler 并运行了bundle install
这是详细的错误：-

In Gemfile:
mini_racer
我根据相关链接研究了该问题：https://github.com/discourse/mini_racer/issues/104
并基于几个堆栈溢出帖子，我卸载了 libv8 gem，然后尝试gem install mini_racer。不幸的是，它没有用
即使再次重新安装 ruby 也没有任何效果。我该如何解决这个问题？
这个堆栈溢出帖子是针对类似于 minesimilar post 的问题，它说设置不同的版本可能是最好的，不太确定哪个是 ruby (2.1.5) 和 rails ( 3.2.xx)
【问题讨论】：
-
可能重复：ld: library not found for -lstdc++.6。 tl;dr：这个库在 XCode 8 中被弃用，在 XCode 10 中被移除。
-
你试过运行
xcode-select --install吗？
