我在加载 rugarch 时遇到问题。我可以安装没问题
install.packages('rugarch')
但是，当我尝试加载它时，出现错误
library(rugarch)
Error : .onLoad failed in loadNamespace() for 'rgl', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.2/Resources/library/rgl/libs/rgl.so':

Reason: image not found
Error: package or namespace load failed for ‘rugarch’
我已经尝试升级 R，重新安装包都无济于事。这是我的系统设置：

任何帮助，将不胜感激。我也尝试从 cran 页面下载它，但这给出了同样的错误。对于它的价值，rugarch 将在我运行3.2.064 位计算机的 Windows 计算机上安装和加载。
我试图从https://cran.r-project.org/src/contrib/Archive/rugarch/安装旧版本的 rugarch，但它甚至不会安装。我试过了1.3-3, 1.3-1, and 1.2-9。这是我得到的错误：
