mysql2捆绑包安装失败

我正在尝试安装mysql2

我已将此添加到我的配置中：

bundle config build.mysql2 --with-mysql-config=/usr/local/Cellar/mysql/5.6.26/bin/mysql_config

但在运行bundle安装时收到此错误：

我已经搜索了与rb_线程_阻塞_区域相关的解决方案，但没有找到任何有效的解决方案

Ruby:Ruby 2.2.1p85

使用Brew安装mysql

更新：

我能够向bundle配置添加所需的额外标志，这使我能够很好地运行bundle安装

您可以将bundle配置为使用本地mysql的头构建mysql2，并设置标志以解决rb_线程_阻塞_区域：

bundle config build.mysql2 --with-mysql-config=/usr/local/Cellar/mysql/5.6.26/bin/mysql_config --with-cflags=\"-DHAVE_RB_THREAD_BLOCKING_REGION\"

但是，当我运行sphinx搜索时，会出现以下错误：

让我们看看您用来安装mysql的命令。在使用apt get的ubuntu上，命令是：sudo apt get install mysql server mysql client libmysqlclient-dev。请注意，除了基本包之外，还有一些库。我怀疑你遇到了类似的情况。@Daiku OP显然不在Ubuntu上，这一行正在检查mysql.h。。。是，明确说明安装了mysql dev。可能与
