libv8 - system

First, you need to have libv8 installed on your Mac:

brew tap homebrew/versions
brew install v8-315

libv8 - gem

Then, you need to check version of the gem that failed to install, it’s usually in line containing
```
Make sure that `gem install libv8 -v '3.16.14.19'` succeeds before bundling.
```
Finally, you have to install the gem with passing system libv8 to the gem command:
```
gem install libv8 -v '3.16.14.19' -- --with-system-v8
```

therubyracer

Similarly to libv8 gem, here you’ll also need to check the gem version.
Then, you need to pass libv8 directory to the gem install command:
```
gem install therubyracer -v '0.12.2' -- --with-v8-dir=/usr/local/opt/v8\@3.15/
```
This directory may change because of using newer version of libv8.
