Can't install flextable

问题

I'm having an issue installing Flextable, and it seems to be because of the gdtools package. It looks like gdtools relies on a .dylib file? Any ideas?

> install.packages("flextable")

  There is a binary version available but the source version is later:
          binary source needs_compilation
flextable  0.4.0  0.4.2             FALSE

installing the source package ‘flextable’

I managed to solve this by reinstalling quartz: https://www.xquartz.org

For mac users. This is sometimes happening with mac os X updates. This requires Homebrew(it can be installed with the following command:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Close all R sessions (not mandatory but from experience, it's the best solution).

In a terminal, run the following commands:

brew update
brew upgrade
brew reinstall cairo

Open an R session and run the following code:

install.packages("gdtools", type = "source")
