Unable to install therubyracer on Mac OS Mojave (10.14.1) #452

While trying to install therubyracer on Mac OS 10.14.1 with command sudo gem install therubyracer

I get following error

/Library/Ruby/Gems/2.3.0/gems/libv8-3.16.14.19/ext/libv8/location.rb:36:in `block in verify_installation!': libv8 did not install properly, expected binary v8 archive '/Library/Ruby/Gems/2.3.0/gems/libv8-3.16.14.19/vendor/v8/out/x64.release/obj.target/tools/gyp/libv8_base.a'to exist, but it was not found (Libv8::Location::Vendor::ArchiveNotFound)

I checked if libv8 is installed with command

gem list -i libv8

It returns true

I was able to solve this issue by providing clang compiler provided by brew, instead of using clang provided by Xcode command line tools.

brew install llvm

Installed missing headers using by following this blog https://donatstudios.com/MojaveMissingHeaderFiles

Installed the ruby racer with brew's llvm

sudo gem install therubyracer -- --with-cxx=/usr/local/opt/llvm/bin/clang++

if Xcode command line tools are no longer supported by therubyracer, then it should be added to the documentation.

thx @vipin04 this saved me a bunch of hours of struggling. I'm migrating an old ruby project to Mojave. I would like to add that yuo can also configure bundler to use the clang compiler provided by brew with:

bundle config build.therubyracer --with-cxx=/usr/local/opt/llvm/bin/clang++
