我正在尝试mysql2为 Ruby 2.0.0 安装 gem。

我尝试按照http://rorguide.blogspot.hk/2011/03/installing-mysql2-gem-on-ruby-192-and.html的说明进行操作，但没有成功。鉴于下面的错误消息，谁能帮我解决这个错误？

checking for main() in -llibmysql... no

你缺少 libmysql-headers。

编辑：是重复的：在 Windows 上安装 mysql-2.9.0 gem 由于缺少 libmysql 而失败

llibmysql 错误意味着 ruby​​ 看不到 libmysql.dll。我刚才得到了错误，所以我将 libmySQL.dll 复制到 $mysqldir/lib 并得到另一个错误

checking for main() in -llibmysql... yes
checking for mysql.h... no
checking for mysql/mysql.h... no
-----
mysql.h is missing.  please check your installation of mysql and try again.

所以，现在 ruby​​ 可以看到 libmysql.dll，但现在它需要 mysql 文件。我再次启动 mysql 安装程序并选择我需要包含文件。2 分钟 - 我得到了包含目录。再次启动gem install mysql2....并得到1 gem installed.

如果像我一样，您有一些同事正在使用 Windows（在我的情况下为 Windows 7）从事 Rails 项目。为了安装 gem “mysql2”，您需要在命令行中指定使用库的路径。

先决条件：已安装 MYSQL。

要运行的命令行（将路径替换为您的安装路径）

 gem install mysql2 — ‘–with-mysql-lib=”c:\Program Files\MySQL\MySQL Server 5.6\lib” –with-mysql-include=”c:\Program Files\MySQL\MySQL Server 5.6\include”‘

你的错误清楚地表明它是关于你的Devkit 所以你可以从

http://rubyinstaller.org/downloads

并按照以下步骤操作

https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

这将解决您的问题
