install older version of therubyracer(v0.9.10) gem on mac mojave - ruby-on-rails

Question

It's my very first time with ruby on rails.
I cloned this project from github.
https://github.com/fredwu/angel_nest
it took me a while to setup and figure out things.
i'm having a lot of compatibility issues as this project was made a long time ago.
when i do "bundle install"
I get this error and bundler stops.
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

succeeds before bundling.
i've tried all approaches available on stackoverflow for this method but none works!
is there any way to override the requirements of this gem make changes such that project works on the newer version of therubyracer gem

Answer 1

This version is locked only by Gemfile.lock, which means that there're probably no specific requirements in project itself.
You can try updating just this gem without full bundle update via: bundle update therubyracer, most probably newer version will do ok.
