我需要获取sf的0.9版本才能使用星标和mapsapi（星标需要sf = <。9）。我目前有SF版本8.1。我正在使用macOS Catalina，我的R版本是1.1.463
我当前的科幻小说链接到GEOS 3.7.2，GDAL 2.4.2，PROJ 5.2.0，而我的rgdal版本是1.48
我尝试按照此处的说明进行安装：https://github.com/r-spatial/sf 因为我已经安装了gdal
install.packages("sf", configure.args = "--with-proj-lib=/usr/local/lib/")
但是我得到这个错误
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
configure: CC:
configure: CXX:
checking for gdal-config... no
no
configure: error: gdal-config not found or not executable.

* restoring previous ‘/Library/Frameworks/R.framework/Versions/3.5/Resources/library/sf’
Warning in install.packages :

不确定如何解决此错误，我是一个新手，所以希望您能获得一些详细的说明！谢谢
