Question

我正在尝试在R中安装udunits2以满足ggforce包的依赖性。但是，安装程序在检查udunits2时仍然失败。我已经尝试了this中的说明（如图所示安装了udunits 2 devel here。）和this线程，它使same result产生install.packages('udunits2')。

我能够通过安装udunits2-dev让我的Mint机器工作，但是我对Fedora很新，并且不确定是什么导致了这个。

系统信息：

Fedora 28，R-3.4.4

修改

尝试使用install.packages("udunits2", configure.args = "--with-udunits2-lib=/usr/bin/udunits2")进行安装时输出错误：

     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.

Answer 1

在Fedora上，头文件安装在/usr/include/udunits2，c.f。这Github issue。在那里提供解决方案：

sudo yum install udunits2-devel

其次是：

install.packages("udunits2",configure.args='--with-udunits2-include=/usr/include/udunits2/')

Answer 2

从以下网站获取udunits2的源代码：ftp://ftp.unidata.ucar.edu/pub/udunits

下载，编译和安装udunits2：

# Download the library
wget ftp://ftp.unidata.ucar.edu/pub/udunits/udunits-2.2.26.tar.gz

# Decompress the archive
tar xf udunits-2.2.26.tar.gz

# Configure the build for your system
./configure prefix=$HOME/.local

# Use 4 jobs to build quickly
make -j 4

# Install to our prefix
make install

启动新的R会话并安装udunits2 R软件包：

（请确保将$HOME更改为您的实际家庭路径）

install.packages(
  "udunits2",
   configure.args = '--with-udunits2-include=$HOME/.local/include/'
)

在此系统上测试过：

R version 3.4.0 (2017-04-21)
Platform: x86_64-pc-linux-gnu (64-bit)
Running under: Red Hat Enterprise Linux Server release 6.5 (Santiago)

Answer 3

作为未经 sudo yum 许可的超级计算机服务器用户，我发现安装udunits2-devel非常困难。另外，我发现spack https://spack.readthedocs.io/en/latest/basic_usage.html 对于安装udunits2＆units R软件包非常有用：

spack install r-udunits2
spack install r-units

Spack将自动安装相关的软件包，而我不必自己安装udunits2-devel。由于我已为ggforce R软件包安装了Units R软件包，而spack无法安装ggforce，因此我需要在输入R之前先加载设备，然后再安装ggforce：

$source <(spack module tcl loads r-units)
$source <(spack module tcl loads r-udunits2)
$R
>install.packages("ggforce")

一切都很好。

udunits2 R安装：找不到udunits2.h
