Error installing libv8: ERROR: Failed to build gem native extension

Question

I made a rails project with,

rails new test_bootstrap.

succeeded.

moved to the project dir and added the gems

gem \         


        

Answer 1

Other workaround to fix the problem is to separate them in the Gemfile

group :production do
 gem 'libv8', '~> 3.11.8.3'
 gem 'therubyracer', :platform => :ruby
end

And then run the bundle command: bundle install --without production

Answer 2

Resolved libv8 3.16.14.7 issue using below command:

gem install libv8 -v '3.16.14.7' -- --with-system-v8

And then bundle install successfully completed.

Answer 3

found this on github

assuming you have tried the mentioned steps above, installed v8-315 and v8 via brew.

brew unlink v8
brew link --force v8-315
gem install therubyracer -v '0.12.2' -- --with-system-v8

Answer 4

try this one:

gem install libv8 -v '3.16.14.3' -- --with-system-v8

Note : Because libv8 is the interface for the V8 engine used by therubyracer, you may need to use libv8, even if you have V8 installed already. If you wish to use your own V8 installation, rather than have it built for you, use the --with-system-v8 option.

For more you can go through the documentation of libv8 on github

Answer 5

That works for me. Put that in your Gemfile

gem 'libv8', '~>3.16.14.7'

Answer 6

I tried the below commands on my local, it worked fine:

brew install v8@3.15
gem install libv8 -v 'YOUR_VERSION' -- --with-system-v8
gem install therubyracer -v 'YOUR_VERSION' -- --with-v8-dir=/usr/local/opt/v8@3.15
bundle install
