我使用的是一台带有M1芯片和R版本4.2.2的新Mac笔记本电脑，在尝试在RStudio中安装sf时出现以下错误。我该如何解决这个问题?
> install.packages("sf")

如果我尝试在base R中安装它，我得到:

In addition: Warning messages:

我遇到了类似的问题，并解决了从https://cran.rstudio.com/bin/macosx/big-sur-arm64/contrib/4.2/sf_1.0-9.tgz下载.tgz文件
install.packages("/Users/XX/Downloads/sf_1.0-9.tgz", repos=NULL, type="source")
安装它
