这里有很多解决方案;可以尝试下,我就是在这里最终解决了问题;

Error in utils::readRegistry("SOFTWARE\\MySQL AB", hive = "HLM", maxdepth = 2) :Registry key 'SOFTWARE\MySQL AB' not found

Error : .onLoad failed in 'loadNamespace' for 'RMySQL'

解决方案1 3.02版本:

Manually add MYSQL_HOME="c:/mysql" variable to the list of system variables

解决方案2 2.02版本: MYSQL_HOME=D:\MySQL\MySQLServer 5.5

保存。然后修改该文本名和拓展名，改为Renviron.site 。把它放在文件夹D: \R\R-2.15.2\etc中

在出现 gcc 安装过程中失败 ;

很可能是因为 cpu导致;

如果是64bit mysql 把 C:\Program Files\R\R-2.12.1\bin\x64 加入到环境变量中

如果是32bit cpu ,C:\Program Files\R\R-2.12.1\bin\i302 加入到环境中

I was having this same problem on Windows 7 with R 2.12.1 x64 and resolved it by:

Changing the R directory in my PATH variable to C:\Program Files\R\R-2.12.1\bin\x64(rather than just ...\R-2.12.1\bin).
Copying ...\MySQL Server 5.5\lib\libmysql.dll to ...\MySQL Server 5.5\bin\.
Running R CMD INSTALL RMySQL_0.7-5.tar.gz in cmd.exe (install.packages('RMySQL',type='source') in R still would not work).

library("RMySQL", lib.loc="C:/Program Files/R/R-3.0.2/library")

Error: 程辑包‘RMySQL’没有安装在'arch=x64'中

切换 rstudio到 32 bit R环境中, tools ---options
