我不知道为什么我的RMySQL软件包无法安装-这是我得到的：

> install.packages('RMySQL',type='source')
trying URL 'http://cran.mirrors.hoobly.com/src/contrib/RMySQL_0.7-5.tar.gz'
Content type 'application/x-gzip' length 160769 bytes (157 Kb)

* installing *source* package 'RMySQL' ...
ERROR: configuration failed for package 'RMySQL'
* removing 'C:/PROGRA~1/R/R-212~1.0/library/RMySQL'

The downloaded packages are in '(foo)'

Warning message:
In install.packages("RMySQL", type = "source") : installation of package 'RMySQL' had    non-zero exit status

我认为MySQL安装没有问题，因为正确的值似乎在注册表中：

> Sys.getenv('MYSQL_HOME')
                 MYSQL_HOME "C:/PROGRA~1/MySQL/MYSQLS~1.1/" 
> readRegistry("SOFTWARE\\MySQL AB", hive="HLM", maxdepth=2)
$`MySQL Server 5.1`
$`MySQL Server 5.1`$DataLocation
[1] "C:\\Documents and Settings\\All Users\\Application Data\\MySQL\\MySQL Server 5.1\\"

$`MySQL Server 5.1`$FoundExistingDataDir 
[1] "0"

$`MySQL Server 5.1`$Location 
[1] "C:\\Program Files\\MySQL\\MySQL Server 5.1\\"

$`MySQL Server 5.1`$Version
[1] "5.1.54"

困惑。任何帮助将不胜感激！
