[英]Why do I get “JNI_GetCreatedJavaVMs returned -1” error while loading the xlsx package in R?
I just downloaded xlsx package in R, but I just can't use the library. 我只是在R中下载了xlsx软件包,但无法使用该库。 (On Mac) (在Mac上)
> library(xlsx)
JavaVM: requested Java version ((null)) not available. Using Java at "" instead.
JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.
Error : .onLoad failed in loadNamespace() for 'xlsx', details:
call: .jinit()
error: JNI_GetCreatedJavaVMs returned -1
Error: package or namespace load failed for ‘xlsx’
What am I doing wrong? 我究竟做错了什么?
Make sure you have installed the dependencies: 确保已安装依赖项:
And, of course, if that does not work, verify you have the Java JDK installed in your mac: javac -version
If not, just install it from here: https://java.com/en/download/faq/java_mac.xml 并且,当然,如果那行不通,请验证您的Mac中是否安装了Java JDK: javac -version
如果没有,只需从以下位置进行安装: https : //java.com/en/download/faq/java_mac。 XML文件
