我正在尝试在Jupyter Notebook的R中运行trControl。
但是当我尝试跑步时，我得到了：
1 package is needed for this model and is not installed. (klaR). Would you like to try to install it now?
所以我尝试使用：
install.packages('klaR')
但是系统给了我以下错误信息：
also installing the dependencies ‘e1071’, ‘classInt’, ‘questionr’
Warning message in install.packages("klaR", repo = "https://mac.R-project.org"):
“installation of package ‘e1071’ had non-zero exit status”
Warning message in install.packages("klaR", repo = "https://mac.R-project.org"):

如何解决此问题？谢谢！
