各位大神，我的Rstudio安装某些包的时候，如“maptools”、“e1071”等，会出现不能安装的情况（其他包能安装）出错如下：Package which is only available in source form, and may need compilation of Fortran: ‘e1071’。求问怎么解决啊？

正常都可以安装：
> install.packages('e1071')

如果不行可以试试下面（国内的镜像）：
install.packages('<package_name>', repo='https://mirrors.tuna.tsinghua.edu.cn/CRAN/')
