R: package or namespace load failed for 'forecast'

问题

I'm working on RStudio, and I have the forecast package installed, if I look at the lateral bar, it's there.

However, when I run library("forecast"), it gives me the following error:

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’

There is indeed no package called ggplot2 but I've never had this issue before. When I try to install ggplot2 just in case I get the error:

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

Which is I guess a related issue.

I've trying the following as is suggested here, with no success:

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

What can I do?

Edit:

This is the output of sessionInfo():
