在构建本机扩展时,
gem
正在寻找mysql头。它们可能位于/Application/XAMPP/…
中,您可以通过以下参数将它们指向gem
-
--with-mysql-dir=/path/to/mysql \
--with-mysql-include=/path/to/mysql/headers \
--with-mysql-lib=/path/to/lib \
--with-mysql-config=/path/to/configs
或者,如果不需要使用XAMPP的mysql,您可以通过获取mysql,然后-
brew install mysql
gem install mysql2
我更喜欢第二条路。它更干净、更容易理解,因为我不知道XAMPP对其捆绑的mysql做了哪些更改;)
稍后,如果您需要在linux vps上安装此类gems,并且遇到类似问题,请记住安装
-dev
软件包。例如,mysql的libmysqlclient-dev
我会安装brew,但我只是想知道它是否会与我现有的XAMPP的mysqlXAMPP的mysql实例的安装冲突,只有在运行它时才会出现。因此,如果您退出它,它不应该与brew的mysql冲突。要使两者同时运行,您可以更改XAMPP one的端口。另外,请务必在brew安装mysql
后查看说明。它指向了一些信息,比如如何在启动后自动启动、停止和运行mysql。
