mysql2 gem安装错误

Question

在捆绑安装失败后，我试图安装mysql2 gem。当我跑的时候

$ sudo创业板安装--with-mysql-config=/usr/local/mysql/bin/mysql_config mysql2

我得到以下错误：

$ where mysql

/usr/local/bin/mysql

我遗漏了什么？

Answer 1

如果您计划在应用程序中使用mysql2 gem，那么在执行此操作之前，您需要安装libmysqlclient-dev包。欲了解更多细节：

Answer 2

试试这个，希望能帮上忙

cd /usr/local/lib/ruby/gems/1.8/gems/mysql-2.7

gem安装mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config

如果这不起作用，那么安装libmysqlclient15-dev

当您无法构建“本机扩展”时，就意味着缺少了一些lib或lib-dev。一般来说，你需要做一个

sudo apt-get install 
lib-???-dev

或sudo apt-get install build_essential.

'sudo apt-get install libmysqlclient15-dev'
