Question

Rails要求我成功使用gem install mysql2并尝试我得到以下错误。那么这个错误主要是什么问题？错误详情如下：由于某些原因，可能无法创建Makefile 必要的库和/或标题。检查mkmf.log文件以获取更多信息细节。您可能需要配置选项。

    Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/mysql2-0.3.7 for  inspection.
   Results logged to /usr/local/lib/ruby/gems/1.9.1/gems/mysql2-0.3.7/ext/mysql2/gem_make.out

的结果出现此错误

       sudo gem install mysql2

安装mysql有什么问题吗？请告诉你对此的了解，我非常感谢你花时间阅读我的问题。

Answer 1

如果你还没有安装mysql，请尝试添加以下完整包：

sudo apt-get install mysql-server mysql-server-5.1 libmysql-ruby libmysqlclient-dev mysql-client-5.1 mysql-common

另请查看此heroku db:pull cant connect to my DB in ubuntu

这应该可以解决您的问题

sudo apt-get install libmysqld-dev libmysqlclient-dev mysql-client

gem install mysql2
