Question

系统：

操作系统：Mac High Sierra（10.13.6）
Ruby：2.5.3
路轨：5.1.6
捆绑器：1.16.4

在包含对本机扩展的sassc 2.0.0依赖项的Rails应用程序上运行bundle install会导致编译错误。

An error occurred while installing sassc (2.0.0), and Bundler cannot continue.
Make sure that `gem install sassc -v '2.0.0' --source 'https://rubygems.org/'` succeeds before bundling.

关于如何解决的研究

尝试-基于github sassc中的建议

最终，此建议建议与捆绑程序分开进行编译，并解决所有编译错误，然后再次尝试捆绑程序。按照上一个参考文件（build-on-darwin）中的说明进行操作，我可以直接进行构建，但是仍然使用bundler遇到相同的编译器错误。

Answer 1

需要更新gcc。我尝试使用Homebrew进行更新，并在/usr/local中遇到权限错误。

解决方案：

$ sudo chown -R $(whoami) $(brew --prefix)/*
$ brew upgrade gcc
$ bundle install

参考：https://github.com/Homebrew/brew/issues/3228

Answer 2

这就解决了：

gem install sassc --version=2.1.0 -- --disable-march-tune-native

sassc捆绑程序错误：Gem :: Ext :: BuildError：错误：无法构建gem本机扩展
