R - 無法安裝xlsxjars，64位Windows，但試圖加載i386

Question

我一直在這個問題太長，現在任何幫助歡迎。我終於安裝並加載了rJava，並且作爲它的一部分，我安裝了64位JRE和JDK。 [R版本3.2.2，64位，64位的Windows 7.Trying運行安裝xlsxjars（對於XLSX包）給出了一個很長的錯誤：

> install.packages("xlsxjars") 
Installing package into ‘C:/Users/usr/Documents/R/win-library/3.2’ 
(as ‘lib’ is unspecified)

The downloaded source packages are in

我的I386和64架構的迷戀，但我不確定這是否是現在的核心問題。我試過手動將JAVA_HOME設置爲下面的地址，並且設置爲=「」，但是出現同樣的錯誤。

> system("java -version") 
java version "1.8.0_65" 
Java(TM) SE Runtime Environment (build 1.8.0_65-b17) 
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode) 
> library(rJava) 
> Sys.getenv("JAVA_HOME") 
[1] "C:/Program Files/Java/jdk1.8.0_65/jre/" 

我還安裝了32位的JDK，以防解決問題，但沒有骰子。這可能是更多關於Java比xlsxjars，因爲我試圖安裝XLConnect作爲一種變通方法，但來到了一個類似的錯誤：

> install.packages("XLConnect") 
Installing package into ‘C:/Users/usr/Documents/R/win-library/3.2’
