R：“预测”的包或名称空间加载失败

Question

我正在使用RStudio，并且已经安装了forecast软件包，如果我看一下侧边栏，它就在那里。

但是，当我运行library("forecast")时，出现以下错误：

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  there is no package called ‘ggplot2’
In addition: Warning message:
package ‘forecast’ was built under R version 3.3.3 
Error: package or namespace load failed for ‘forecast’

确实没有称为ggplot2的软件包，但我以前从未遇到过此问题。当我尝试安装ggplot2时，以防万一出现错误：

Warning in install.packages :
  installation of package ‘ggplot2’ had non-zero exit status

我猜这是一个相关问题。

我正在尝试以下建议的here，但没有成功：

remove.packages(c("forecast","ggplot2"))
install.packages('ggplot2')
install.packages('forecast')

我该怎么办？
