在 Mac 上安装 RWeka

Question

我正在尝试在 mac 上安装 RWeka 包。

操作系统版本:

10.9.5

安装的Java版本:

java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)

执行后

install.packages("RWeka")

当我尝试执行

library(RWeka)

显示以下错误

Error : .onLoad failed in loadNamespace() for 'RWekajars', details:
call: .jinit()
error: JNI_GetCreatedJavaVMs returned -1

Error: package or namespace load failed for ‘RWeka’
JavaVM: requested Java version ((null)) not available. Using Java at "" instead.
JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib
