我正在尝试安装"choroplethr.">
我已经阅读了以下相关的查找错误：
- https://askubuntu.com/questions/1057100/error-libudunits2-a-not-found-when-installing-ggraph-additional-error-objec
- 安装R3.3的udunits2软件包
他们的建议是安装我已经安装的东西。我在标准位置安装了libudunits2，带有：
$ sudo apt-get install libudunits2-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libudunits2-dev is already the newest version (2.2.26-1).
我可以看到标题：
$ ll /usr/include/ | grep unit
-rw-r--r-- 1 root root 39998 Jan 5 2018 udunits2.h
-rw-r--r-- 1 root root 5195 Jan 5 2018 udunits.h
然而，在安装时，我得到了这个错误：
$ R
R version 3.5.1 (2018-07-02) -- "Feather Spray"
> install.package("choroplethr", dep=T)
...
configure: error: in `/tmp/RtmpWC06JV/R.INSTALL7cbb4928db67/units':
configure: error:
--------------------------------------------------------------------------------
Configuration failed because libudunits2.so was not found. Try installing:
* deb: libudunits2-dev (Debian, Ubuntu, ...)
* rpm: udunits2-devel (Fedora, EPEL, ...)
* brew: udunits (OSX)
If udunits2 is already installed in a non-standard location, use:
--configure-args='--with-udunits2-lib=/usr/local/lib'
if the library was not found, and/or:
--configure-args='--with-udunits2-include=/usr/include/udunits2'
if the header was not found, replacing paths with appropriate values.
You can alternatively set UDUNITS2_INCLUDE and UDUNITS2_LIBS manually.
--------------------------------------------------------------------------------
我已经做了这些设置，但是
install.packages("udunits2", configure.args = '--with-udunits2-include=/usr/include/udunits2')
-----Error: libudunits2.a not found-----
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.
我错过了什么？这个软件包只是OSX吗？
对于带有R 3.5的Ubuntu，您可以使用c2d4u3.5 PPA，该PPA由在CRAN上为您带来R Ubuntu软件包的同一个人提供。https://cran.r-project.org/bin/linux/ubuntu/README.html和http://dirk.eddelbuettel.com/blog/2017/12/22/:
sudo add-apt-repository ppa:marutter/c2d4u3.5
sudo apt-get update
之后，您可以为大多数CRAN软件包安装二进制软件包：
sudo apt-get install r-cran-choroplethr
这应该适用于CRAN任务视图中提到的所有包。
除此之外，我试图使用docker:重现您的安装问题
FROM ubuntu:18.04
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update
&& apt-get install --yes --no-install-recommends gnupg ca-certificates
&& apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
&& echo "deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/" >> /etc/apt/sources.list
&& apt-get update
&& apt-get install --yes --no-install-recommends r-base-dev libudunits2-dev
&& Rscript -e 'install.packages(c("units", "udunits2"))'
然而，这个形象是毫无问题地建立起来的。
