英文:
Unable to compile 'sass' when trying to install package with R
问题
当在Rstudio中运行install.packages("sass")时，下载成功，但在编译过程中发生错误：
...
g++ -std=gnu++14 -Wall -O2 -std=c++11 -I /usr/local/lib/libsass/include -fPIC -c -o src/ast.o src/ast.cpp
In file included from src/ast.cpp:3:
src/sass.hpp:72:43: error: ‘SASS_STYLE_TO_CSS’ was not declared in this scope; did you mean ‘SASS_STYLE_TO_SASS’?
72 | const static Sass_Output_Style TO_CSS = SASS_STYLE_TO_CSS;
| ^~~~~~~~~~~~~~~~~

我尝试使用install_github安装rstudio/sass的较早版本，如这里建议的方式，但遇到了相同的编译错误。
（我需要此软件包作为其他软件包的依赖项，尤其是rmarkdown）
以下是我的计算机信息（sessionInfo()的输出）：
R版本 4.2.3（2023-03-15）
平台：x86_64-pc-linux-gnu（64位）
运行环境：Ubuntu 22.04.2 LTS

When running install.packages("sass") in Rstudio, the download succeeds but an error occurs in the compilation :

I have tried to install earlier versions of rstudio/sass with install_github, as advised here, encountering the same compilation error.
(I need this package as a dependency for other ones, notably rmarkdown)
Here is my machine's information (output of sessionInfo()) :
R version 4.2.3 (2023-03-15)

首先确保您的系统已安装必要的开发工具和库：
sudo apt-get update
sudo apt-get install -y build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev
然后，删除最新版本的 LibSass：
sudo apt-get remove libsass
然后安装它：
git clone https://github.com/sass/libsass.git
cd libsass
git checkout tags/3.6.5 # 如果需要，替换为最新版本
make -j4
sudo make install
现在，在 R 中安装 'sass' 包：
install.packages("sass")
如果仍然无法正常工作，请尝试在 GitHub 上直接安装：
if (!requireNamespace("remotes", quietly = TRUE))
install.packages("remotes")
remotes::install_github("rstudio/sass")
您还可以尝试使用 R 中的 'devtools' 包安装 'sass' 包：
首先，如果尚未安装 'devtools' 包，请执行以下命令：
install.packages("devtools")
然后加载 'devtools' 包：
library(devtools)
最后，尝试安装 'sass'：
devtools::install_github("rstudio/sass")
如果仍然无法正常工作，您可以尝试在 GitHub 上联系他们。
英文:
first make sure you have the necessary development tools and libraries installed on your system with
sudo apt-get update
sudo apt-get install -y build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev
then remove the latest version of LibSass sudo apt-get remove libsass then install it
git clone https://github.com/sass/libsass.git
cd libsass
git checkout tags/3.6.5 # Replace '3.6.5' with the latest version, if necessary
make -j4
sudo make install
now Install the 'sass' package in R install.packages("sass")
if that still dont work try directly on the github
if (!requireNamespace("remotes", quietly = TRUE))
install.packages("remotes")
remotes::install_github("rstudio/sass")
You can also try by installing the 'sass' package using the 'devtools' package in R:
first install the devtools package if not already install.packages("devtools") then load it library(devtools) and we try to install sass devtools::install_github("rstudio/sass")
if still not maybe reach them on github

如在这些幻灯片（来自这个博客）中所描述，我能够通过运行以下命令来安装该软件包：
export DEBIAN_FRONTEND=noninteractive
apt update && apt install -y software-properties-common
add-apt-repository -y ppa:c2d4u.team/c2d4u4.0+
echo "deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/" > /etc/apt/sources.list.d/cran.list
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
apt update && apt install -y r-cran-sass
由于这个PPA，我现在可以使用apt从cran镜像安装（任何其他）软件包。
英文:
As described in these slides (from this blog), I was able to install the package running those commands :
export DEBIAN_FRONTEND=noninteractive
apt update && apt install -y software-properties-common
add-apt-repository -y ppa:c2d4u.team/c2d4u4.0+
echo ”deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/” > /etc/apt/sources.list.d/cran.list
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
apt update && apt install -y r-cran-sass
Thanks to this PPA, I can now install (any other) packages from the cran mirror with apt .
