安装包：OpenStreetMap出现错误，求大神指教

library(OpenStreetMap)
Error in .jinit() : Cannot create Java virtual machine (-1)
Error : .onLoad failed in loadNamespace() for *OpenStreetMap*, details:
call: fun(libname, pkgname)
error: Java classes could not be loaded. Most likely because Java is not set up with your R installation.
Here are some trouble shooting tips:
1. Install Java
2. Run
R CMD javareconf
in the terminal. If you are using Mac OS X >= 10.7 you may want to try
R CMD javareconf JAVA_CPPFLAGS=-I/System/Library/Frameworks/JavaVM.framework/Headers
instead.
Error: package or namespace load failed for ‘OpenStreetMap’

> library(OpenStreetMap)
Error in get(hookname, envir = env, inherits = FALSE) :

我在RStudio中加载程序包也总是install.packages : cannot open the connection
最后先在R中加载程序，然后再在RStudio中使用
