EDIT: I wrote up a more detailed solution on my blog here if you want to walk through all the steps.
I'm trying to install Jekyll via gem install Jekyll
on macOS Catalina using Ruby install via homebrew and located at /usr/local/opt/ruby/bin/ruby
and I'm running into the following error
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing ffi (1.9.21), and Bundler cannot continue.
I've already tried updating my Xcode Command Line tools via xcode-select --install
but I got back the following message:
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
Does anyone know how I can build libffi
on my machine so that I Jekyll can use it as a dependency?
Aaaaaand I figured it out! Credit to @ffleming here. Here's what you need to do:
brew reinstall libffi
export LDFLAGS="-L/usr/local/opt/libffi/lib"
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
gem install jekyll
and you should be sorted!
