我如何发布h R：
$ LD_LIBRARY_PATH = $（/ usr / libexec / java_home）/ jre / lib / server：open -a RStudio
成功加载rJava和xlsxjars包：
> library（rJava）
> library（xlsxjars）
尝试加载xlsx软件包失败：
> library（xlsx）
JavaVM：请求的Java版本（（null））不可用。而在使用Java代替。
JavaVM：无法加载JVM：/bundle/Libraries/libserver.dylib
JavaVM致命错误：无法加载jvm库。
错误：.onLoad在'xlsx'的loadNamespace（）中失败，详情：
调用：.jinit（）
错误：JNI_GetCreatedJavaVMs返回-1
错误：包或命名空间加载'xlsx'失败
R配置：

JNI链接器标志：-L $（JAVA_HOME）/ lib / server -ljvm
更新/Library/Frameworks/R.framework/Resources中的Java配置
不幸的是，这些符号链接技巧对我没有帮助。但是，我在计算器！ （其他地方;））
这个通过以下方式为我工作：
-
在终端输入以下内容正确重新链接Java：
sudo R CMD javareconf
-
回到R（或RStudio）从源代码安装rJava包：
install.packages（rJava，type ='source'）
希望，这有帮助！

解决方案
Unfortunately, these symlink tricks didn't help me. However, I found a similar issue on stackoverflow! (where else ;)) This one worked for me by doing the following:
In terminal enter the following to relink Java correctly:
sudo R CMD javareconfBack in R (or RStudio) install the rJava package from source:
install.packages("rJava",type='source')
Hope, this helps!
