我一直在尝试安装ncdf R软件包。我已经搜索了答案并尝试解决问题，但看起来我现在是时候在这里寻求帮助了。
我从此页面下载了ncdf_1.6.5.tar.gz（＆＃34; https://cran.r-project.org/src/contrib/Archive/ncdf/），将其保存在下载文件夹中。
由于它没有NAMESPACE文件，我解压缩文件并执行以下操作
cd Downloads
cd ncdf
echo 'exportPattern( "." )' > NAMESPACE
cd ..
tar -zcf ncdf.tar.gz ncdf
然后我尝试通过此命令安装包
R CMD INSTALL -l /Users/xyc/Downloads/ncdf.tar.gz
它给了我这个

ARGUMENT 'INSTALL' __ignor'e__
AVIS : option inconnue '-l'

显然，这没有安装包。
我试图通过
安装在RStudio中install.packages("ncdf.tar.gz", lib = "/Users/xyc/Downloads", repos = NULL)
它告诉我
* installing *source* package ‘ncdf’ ...

** libs
make: error: unable to find utility "make", not a developer tool or in PATH

Warning in install.packages :

有人可以帮助我吗？非常感谢你。
更新 感谢您的所有投入。我下载了Xcode 9和更低版本的ncdf并做了这个
$ sudo xcode-select --switch /Users/xyc/Downloads/Xcode.app
$R CMD INSTALL ncdf_1.6.3.tar.gz
它给了我96个警告和11个错误。编译再次失败。

我也试过这个
$R CMD INSTALL --configure-args="-with-netcdf_incdir=/usr/local/netcdf/4.1.1-gcc/include -with-netcdf_libdir=/usr/local/netcdf/4.1.1-gcc/lib" ncdf_1.6.3.tar.gz

看起来我仍然遇到XCode问题。
所有建议都受到高度赞赏和欢迎。
谢谢...
