【问题描述】：

我对 Rails 开发完全陌生，过去一个月一直在努力安装 mysql2。我有 windows 8.1 64 位，ruby 2.0.0p535 64 位，rails 4.0.2，我有 mysql2 (0.3.14) 64 位。我从 cmd 得到的错误如下。

【问题讨论】：

  • 显示你的 mkmf.log
  • @majioa。刚贴出来。另外 mkmf.log 到底是什么？
  • 看来ruby还没有完全编译好……
  • @majioa 我应该如何解决这个问题？
  • 看到这里遇到类似问题的人的试用手册：redmine.org/boards/2/topics/38765

标签： mysql ruby-on-rails ruby windows mysql2


【解决方案1】： 
C:\Users\tghol_000>gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:\mysql-connector\"' --with-mysql         lib="C:\mysql-connector\lib"'
                                                                                                ^-- remove that '

你有不必要的撇号，我已经检查过它在哪里，删除并重试。

【讨论】：

  • 检查 's 和 "s。错误表明你有一个不匹配的双引号。我不使用 Windows 进行 Rails 开发，但我相信这是可能的，不管“Rails”是什么4 路”说。
