libmysqlclient is missing. You may need to 'apt-get install libmysqlclient-dev' or 'yum install mysql-devel', and try again.

寻求各位大佬帮助

曾尝试 bundle config build.mysql2 --with-mysql-config=/etc/mysql/mysql.conf.d/mysqld.cnf 配置该属性但又会出现其他问题,真是绝了

缺少 mysqlclient 的库,楼主没贴是什么系统没法提供方案。

例如 ubuntu 要装的是 libmysqlclient-dev

额,报错上面说的是没安装 libmysqlclient。

如果你是 ubuntu 就运行 apt-get install libmysqlclient-dev

是 centos 就运行 yum install mysql-devel

然后再 bundle install 试试

你这一周浪费得有点冤,仔细阅读一下错误内容就解决了

libmysqlclient is missing. You may need to 'apt-get install libmysqlclient-dev' or 'yum install mysql-devel', and try again.

已经解决了,我安装的是 mysql-client 看错了 安装完 libmysqlclient 就解决了 感谢大家
