The command "npm install jest-expo" failed and exited with 1 during

Issue:
I tried a very simple implementation for a bare bones repo - the travis yaml has only the failing command.

Goal
Get travis to successfully build and run tests for expo with detox

.travis.yml

os: osx
  
install:
- npm install jest-expo

You are using Ruby as the language, while using npm to manage your dependencies. I donā€™t know off hand what version of Node.js and npm your image has, but whatever the case, Iā€™d first try using language: node_js and find a reasonable version that works.

After specifying node language and adding a target version (one from my local machine that successfully runs detox tests), the build errored with the same output

The log says thereā€™s a problem with detox@15.4.1 postinstall script and thereā€™s some helpful output from that script above that. Itā€™s your job to diagnose it. Thereā€™s no visible issue on Travis side so far.

@native-api thank you. Iā€™ll take a look.
