我有一台Windows 8.1计算机，并使用R 3.0.3和RTools30。我正在尝试安装RMySQL，我按照http://www.ahschulz.de/2013/07/23/installing-rmysql-under-windows/和另一个StackOverflow帖子中的说明进行操作，但是我一遍又一遍地遇到此错误：

你能帮我么？谢谢...
最佳答案
您的MySQL安装可能出了点问题。
该错误是指注册表项丢失，如此处记录：MySQL Manual - MySQL Installation，搜索SOFTWARE \ MySQL AB将显示说明注册表外观的部分。使用regedit.exe，您可以自己修复此问题。
