Question

我已经在这个问题上挂了好几个小时了，以前发现的关于此问题的任何信息似乎都没起作用。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'

我正在运行MacOS High Sierra，并通过Homebrew安装了MySQL。我尝试以bundle install --system的身份运行，将/tmp/mysql.sock添加到我的database.yml中（已经存在），并且重新安装了系统上几乎所有相关的开发工具，但都没有运气。

还值得注意的是，我过去确实做到了这一点……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。

感谢您可以提供的帮助

更新：我可以在运行gem install mysql2 -v '0.4.5' -- --srcdir=/usr/local/Cellar/mysql/8.0.11/include/

的情况下正确安装mysql2 v0.4.5的gem

Answer 1

所以问题最终是由于自制软件最近使mysql v8.x.x成为标准安装，并且我进行了自制软件升级，这使我脱离了我们代码库支持的标准...备受关注。一旦我将系统的mysql版本降下来以准确反映mysql2的需求，它就起作用了。
