使用MySQL启动Rails服务器时出错

Question

我在Windows 7的Ruby 2.0.0上运行Rails 4.0.3，并安装了DevKit（全部为x64）。 我已经使用subst X: "C:\\Program Files\\MySQL\\MySQL Server 5.6"安装了mysql2 gem subst X: "C:\\Program Files\\MySQL\\MySQL Server 5.6" ，然后gem install mysql2 --platform=ruby -- --with-mysql-dir=X:并且它已经安装精细。 然后，我用新的rails new mysql_testy创建了一个新应用，该应用运行良好，但是当我运行rails server ，出现以下错误：

C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql2-0.3.15/lib/mysql2.rb:8:in 'require': 193: %1 is not a valid Win32 application.   - C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql2-0.3.15/lib/mysql2/mysql2.so (LoadError)

from bin/rails:4:in `<main>'`

你们知道发生了什么吗？

Answer 1

不知道您是否知道了，但是我遇到了同样的问题。 我安装了32位sql连接器，从中复制了libmysql.dll文件，并将其粘贴到Ruby / bin文件夹中。 打开一个新的命令提示符，并能够连接到服务器。

但是，在此步骤之前，您可能必须重新安装指向连接器路径的全新MySQL2 gem： gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\\mysql-connector\\mysql-connector-c-6.1.5-win32\\lib" --with-mysql-include="C:\\mysql-connector\\mysql-connector-c-6.1.5-win32\\include" --with-mysql-dir="C:\\mysql-connector"'

希望这可以帮助
