R 安装flextable库时出错

在r studio上安装flextable库时，我遇到以下错误

ERROR: configuration failed for package ‘systemfonts’
* removing ‘/home/user/R/x86_64-pc-linux-gnu-library/3.2/systemfonts’
Warning in install.packages :
  installation of package ‘systemfonts’ had non-zero exit status

The downloaded source packages are in
    ‘/tmp/RtmpN2KD39/downloaded_packages’

尝试安装错误消息显式调用的依赖项：

install.packages("systemfonts")
install.packages("gdtools")
install.packages("flextable")

@Sophia Wilson您的R版本是非常旧的3.2。在按照以下方式安装新软件包之前，您应该升级您的R版本。如果你的组织不允许你升级R版本，你应该考虑学习尽可能多地使用Basic R，或者使用像JooYter笔记本这样的井手/环境。p>

# Install pacakges if they are not already installed: necessary_packages => character vector
necessary_packages <- c("flextable")

# Create a vector containing the names of any packages needing installation:
# new_pacakges => character vector
new_packages <- necessary_packages[!(necessary_packages %in%
                                       installed.packages()[, "Package"])]

# If the vector has more than 0 values, install the new pacakges
# (and their) associated dependencies: varied => stdout
if(length(new_packages) > 0){install.packages(new_packages, dependencies = TRUE)}

# Initialise the packages in the session: bool => stdout
lapply(necessary_packages, require, character.only = TRUE)

#如果尚未安装包，则安装包：必需的_包=>字符向量
必要的字符向量
新包装标准件
if（length（new_packages）>0）{install.packages（new_packages，dependencies=TRUE）}
#初始化会话中的包：bool=>stdout
lapply（必需的包，require，character.only=TRUE）

我已经尝试过了，在install.packages中出现错误

警告：“systemfonts”软件包的安装具有非零退出状态下载的源程序包位于“/tmp/RtmpE9BewA/downloaded_packages”中。
