我正在尝试安装一个名为“ncdf 4”的R包。我已经尝试在R-studio界面的“packages”部分安装它，但也尝试在控制台中输入install.packages("ncdf4")。
这是我在两个示例中得到的输出：

Installing package into ‘/home/user/R/x86_64-pc-linux-gnu-library/3.6’
(as ‘lib’ is unspecified)

configure.ac: starting
checking for nc-config... no
-----------------------------------------------------------------------------------
Error, nc-config not found or not executable.  This is a script that comes with the
netcdf library, version 4.1-beta2 or later, and must be present for configuration
to succeed.

If you installed the netcdf library (and nc-config) in a standard location, nc-config
should be found automatically.  Otherwise, you can specify the full path and name of
the nc-config script by passing the --with-nc-config=/full/path/nc-config argument
flag to the configure script.  For example:

./configure --with-nc-config=/sw/dist/netcdf4/bin/nc-config

Special note for R users:
-------------------------
To pass the configure flag to R, use something like this:

R CMD INSTALL --configure-args="--with-nc-config=/home/joe/bin/nc-config" ncdf4

where you should replace /home/joe/bin etc. with the location where you have
installed the nc-config script that came with the netcdf 4 distribution.

有人能从我提供的代码中破译出错误吗？谢谢。
