MySql gem 安装失败

我正在尝试使用此命令在我的工作站上安装 mysql gem

gem 安装 mysql-2.8.1.gem

输出 ：

ERROR:  Error installing mysql-2.8.1.gem:

Could not create Makefile due to some reason, probably lack of

details.  You may need configuration options.

Provided configuration options:

        --without-libmysqllib


Gem files will remain installed in C:/Ruby187/lib/ruby/gems/1.8/gems/mysql-2.8.1
 for inspection.

m_make.out

因此之前我无法找到“libmysqllib”，直到我将该文件复制到与我手动安装的 gem 相同的目录中。

我使用代理，因此我必须下载 *.gem 文件并从那里安装。

请帮忙。

您缺少一些编译时依赖项。检查事项

  • 您是否安装了 mysql dev 文件，例如在 Ubuntu 上这是 libmysqlclient15-dev

  • 是否安装了 ruby​​1.8.7 dev 文件，例如 ruby​​1.8-dev Ubuntu

您确实不需要复制该库。这表明您可能没有安装 mysqlclient 库。

希望对您有所帮助！
