rails bundle install error therubyracer - ruby-on-rails

Question

i tried installing the gem separately and v8 file also. I'm lost on what to do as I've exhausted all possible options

and *not* the one that is bundle with the libv8 rubygem. However,
it could not be located. please make sure you have a version of
v8 that is compatible with 3.16.14.3 installed. You may
need to special --with-v8-dir options if it is in a non-standard
location

An error occurred while installing therubyracer (0.12.1), and Bundler cannot

Make sure that `gem install therubyracer -v '0.12.1'` succeeds before bundling.
I'm using brew to install ruby and rails using this setup guide
https://gorails.com/setup/osx/10.10-yosemite
Help please, upgrading to Yosemite has totally messed with my dev environment

Answer 1

Perhaps this problem has to do with a recent update of XCode. After a XCode update you need to do the following steps:
Open Xcode and accept the license agreement
Reinstall the Command Line Tools.
The second step seems to depend on your OS versions. If xcode-select --install does not work try to start the Install Command Line Developer Tools app in /System/Library/CoreServices.
After reinstalling the Command Line Tools try to rerun bundle install.

Answer 2

Try this worked for me:
gem install libv8 -- --with-system-v8
gem install therubyracer -v '0.12.1'
if that didn't work try to run:
brew update
and try again the first two steps.

Answer 3

I resolved the same issue by changing the Gemfile
gem 'therubyracer'
was replaced by
gem 'therubyracer', platforms: :ruby
Could you try this?

Answer 4

This worked for Catalina
brew install v8#3.15
gem install libv8 -v 3.16.14.19 -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8#3.15
