Travis build is hanging waiting for user input (To

When building the app with Travis, the build hangs after it tries to install angular. It does this by waiting for input.

I have gone through the docs which show that this is indeed the case when "Waiting for keyboard input or other kind of human interaction". But I get no option of doing this anywhere. My .travis.yml is up to date and does what is expected.

My .yml code

language: node_js
node_js:
  - "11.0"
sudo: required
branches:
  only:
    - master
before_script:
  - npm install -g --silent firebase-tools
  - npm install -g @angular/cli
script:
  - npm install
  - ng build --prod
deploy:
  skip_cleanup: true
  provider: firebase
  token:
    secure: "1/St7DD3G1QTmK-hdghJoK4cS348_bxklRqbuM3t7KGuE"

after_success:
  - firebase deploy --token "1/St7DD3G1QTmK-hdghJoK4cS348_bxklRqbuM3t7KGuE" --non-interactive

You need add this in your .travis.yml file:

before_script:
  - export NG_CLI_ANALYTICS=ci

You can find here a online sample ready for use.

Change in your Travis file

from: npm install -g @angular/cli to: es | npm install -g @angular/cli

This sends one "yes" to the NPM install command.
