当我运行rails服务器时，它会显示如下错误消息：

`require': Incorrect MySQL client library version! This gem was compiled for 6.0.0 but the client library is 5.1.42. (RuntimeError)

我安装了Mysql 5.1数据库。

在我的宝石文件中，我写了这个：

gem 'mysql'

然后运行bundle install

导致此问题的原因是什么？

Answer 1

试试这个

添加Gemfile

 gem 'mysql2'

然后执行bundle install，并在命令行运行此命令以安装这些软件包。

   sudo apt-get install mysql-client libmysqlclient-dev

在Windows上

将libmysql.dll从mysql安装文件夹复制到Ruby bin 系统上的目录。

Answer 2

我认为你应该尝试包含mysql2 gem，在你的gemfile中添加：

gem 'mysql2'

`require'：MySQL客户端库版本不正确
