【解决方案1】：

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")

我已经试过了，收到错误Warning in install.packages : installation of package ‘systemfonts’ had non-zero exit status The downloaded source packages are in ‘/tmp/RtmpE9BewA/downloaded_packages’

@Sophia Wilson 您的 R 版本非常旧 3.2。在以下列方式安装新软件包之前，您应该升级您的 R 版本。如果您的组织不允许您升级 R 版本，您应该考虑学习在尽可能多的工作中使用 Base R，或者使用像 Jupyter Notebook 这样的 IDE/环境。

# 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)
