我知道这已被问过好几次，但是我搜索了一下，我尝试了很多不同的东西，没有任何效果。

Answer 1

我遇到了完全相同的问题。我通过完全卸载MySQL，重新安装64位版本并使用指向MySQL安装的选项安装mysql2 gem来解决它们。

我按照我在petermac.com找到的一些说明：

<强> 1。卸载MySQL ：

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*

edit /etc/hostconfig and remove the line MYSQLCOM=-YES-

sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*

<强> 2。安装MySQL 64位版本

第3。安装mysql2 gem

sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- \
  --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib \
  --with-mysql-include=/usr/local/mysql/include

至少应该安装宝石：）

Answer 2

This blog post解决了我遇到的类似问题。

您需要安装libmysqlclient-dev才能构建mysql2 gem。

MySQL2 Ruby gem不会安装10.6
