安装 R3.3 的 udunits2 软件包

我只是浪费了一整天的时间试图弄清楚如何安装 udunits2 软件包以便能够安装units 软件包以便能够安装ggforce 和ggraph 软件包。

我尝试在 Ubuntu 16.04 和 R >= 3.3 上安装它，因为 ggforce 是在 R 3.3 下构建的。

我在这里遵循了这些说明：https://github.com/edzer/units/issues/1 https://github.com/edzer/units/issues/1

尽管我的机器上安装了 libudunits-2.0 和 udunits （因为 sudo apt-get install udunits2 找不到 udunits2 软件包），并且当我尝试在 R 中时，我的 $PATH 上的 libudunits-2 和 udunits 位置的 PATH安装 udunits2、units 或 ggforce 我收到一条错误消息，

     If the udunits2 library is installed in a non-standard location,
     use --configure-args='--with-udunits2-lib=/usr/local/lib' for   
     example,
     or --configure-args='--with-udunits2-include=/usr/include/udunits2'
     replacing paths with appropriate values for your installation.
     You can alternatively use the UDUNITS2_INCLUDE and UDUNITS2_LIB
     environment variables.
     If udunits2 is not installed, please install it.
     It is required for this package.

所以，嗯，它正在寻找 udunits2.h 和 libudunits2.a 文件...... 因此，我从 CRAN 下载了 udunits2，解压它并将其放入我的 R 库中。 然后，如果我输入library(udunits2, lib.loc =“my library dir”)，我会收到一条错误消息，指出它尚未安装。因此，当我 install.package('udunits2', repo = NULL, libconfig.args = '--with-udunits2-lib=/home/fjay/R/x86_64-pc-linux-gnu-library/3.3') 或install.packages('units',....) 或 install.packages('ggforce',...) 它仍在寻找这些文件...并且，在检查 udunits2 包后，这些文件不在任何udunits2 文件夹。

如果有人知道如何安装这个 udunits2 软件包，请帮助我！

我有同样的问题。根据第一个答案here https://stackoverflow.com/questions/11319698/how-to-install-r-packages-rnetcdf-and-ncdf-on-ubuntu你必须安装-dev的版本udunits:

sudo apt-get install libudunits2-dev

然后安装udunits2 and ggforce没有任何错误。

EDIT:

根据以下评论，对于 CentOS7 应该是：

sudo yum install udunits2-devel

对于 MacOS：

brew install udunits
