在Windows 8.1中安装RMySQL时的另一个错误

Question

I have a Windows 8.1 machine and use R 3.0.3 and RTools 30. I'm trying to install RMySQL and I followed the instructions from http://www.ahschulz.de/2013/07/23/installing-rmysql-under-windows/ and another StackOverflow posts but I get this error over and over:

Can you please help me? Thank you...

Answer 1

Probably something went wrong with your MySQL installation.

The error refers to registry keys missing as documented here: MySQL Manual - MySQL Installation , searching for SOFTWARE\\MySQL AB reveals the section stating how the registry should look like. With regedit .exe you can fix this yourself.

It worked for me with the same problem
