mysql2 捆绑包安装失败

Question

我已经在这个问题上挂了好几个小时了，我之前发现的关于这个问题的帖子似乎都没有用。下面是我运行 bundle install:

时的 mysql2 输出

An error occurred while installing mysql2 (0.4.5), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.4.5'` succeeds before bundling.

In Gemfile:
mysql2

这是我的 Gemfile 的相关部分：

gem 'rails', '5.1.4'
gem 'mysql2', '0.4.5'

我运行正在使用 MacOS High Sierra 并通过 Homebrew 安装了 MySQL。我试过运行ning 作为 bundle install --system，将 /tmp/mysql.sock 添加到我的 database.yml（它已经存在），以及在我的系统上重新安装几乎所有相关的开发工具，都没有运气。

同样值得注意的是，我过去这样做没有任何问题...我不太确定发生了什么变化，但这似乎只是我系统上的一个问题。

感谢您提供的任何帮助

更新：当我运行 gem install mysql2 -v '0.4.5' -- --srcdir=/usr/local/Cellar/mysql/8.0.11/include/

时，我能够正确安装 gem for mysql2 v0.4.5

所以问题最终是自制软件最近使 mysql v8.x.x 成为标准安装，而我运行自制软件升级使我脱离了我们的代码库支持的标准...为将来所记。一旦我降低系统 mysql 版本以准确反映 mysql2 正在寻找的内容，它就起作用了。
