mysql - Windows 7 中的 Ruby on Rails

Question

我正在按照这些视频安装 ruby​​ -

https://www.youtube.com/watch?v=y0X7SUfF928&list=PLcwklDOKWhc-k8VsT-ixbAY0TdQI5JLoW

以前我遇到过这些错误

不正确的 mysql 客户端库版本这个 gem 是为 6.0.0 编译的

然后我点击了这个链接 mysql2 gem compiled for wrong mysql client library

但现在我得到了这些 -

c:/row/Ruby200/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require
': cannot load such file -- mysql2/mysql2 (LoadError)
        from c:/row/Ruby200/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:5
5:in `require'
        from c:/row/Ruby200/lib/ruby/gems/2.0.0/gems/mysql2-0.3.15/lib/mysql2.rb
:8:in `<top (required)>'
        from c:/row/Ruby200/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:1
35:in `require'
        from c:/row/Ruby200/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:1
35:in `rescue in require'
        from c:/row/Ruby200/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:1
44:in `require'
        from test.rb:1:in `<main>'

请帮帮我……

看来您的 MYSQL C-Connector library 版本可能有误安装

你需要 this one :

基本上，Windows 7 不附带任何帮助 gem 运行所需的 MYSQL 头文件。您需要安装 32 位版本的 MYSQL C-Connector，然后使用此命令安装 gem:

gem install mysql2 —platform=ruby — ‘—with-mysql-dir=”C:\mysql-connector-path”’
