推荐答案

它确实告诉您一个通用的可能问题:

It does tell you a generic possible problem:

由于某些原因(可能缺少)而无法创建Makefile 必要的库和/或标头.检查mkmf.log文件以获取更多信息 细节.您可能需要配置选项.

Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

那是你的线索.

确保已安装MySQL客户端存储库以及相关的"devel"软件包.像Ruby,Python,Perl等语言需要安装库和标头,以便它们可以编译本机模块,从而提供从语言到驱动程序的接口.

Make sure you've installed the MySQL client repo, along with the associated "devel" package. Languages like Ruby, Python, Perl, etc., need the libraries and headers installed so they can compile native modules providing the interface from the language to the drivers.

此外,您将需要mysql_config,它是通过以下方式安装的:

Also, you'll need mysql_config, which is installed by:

sudo apt-get install libmysqlclient-dev

我可以使用Ubuntu VM复制您的问题,并在安装libmysqlclient-dev后修复它.

I was able to duplicate your problem with my Ubuntu VM, and fix it after installing libmysqlclient-dev.

它将mysql_config放置在/usr/bin/mysql_config中,并且gem install mysqlgem install mysql2都能够成功安装.

It places mysql_config in /usr/bin/mysql_config, and both gem install mysql and gem install mysql2 were able to install successfully.
