当我运行 rails server 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 gem 文件中，我写了这个：

gem 'mysql'

然后运行捆绑安装

是什么导致了这个问题？

试试这个

添加你的 Gemfile

 gem 'mysql2'

然后进行捆绑安装，并在命令行运行此命令来安装这些软件包。

   sudo apt-get install mysql-client libmysqlclient-dev

在窗户上

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

我认为您应该尝试包含 mysql2 gem，在您的 gemfile 中添加：

gem 'mysql2'
