How to write .travis.yml if my project deps on python and nodejs?

Question

My project includes some python codes and build with grunt.I write .travis.yml like:

language: node_js
before_install:
  - pip inst         


        

Answer 1

It's kind of solved.A sudo must be prepend to 'pip install'.

I guess 'npm install -g grunt-cli' does not need sudo because it's a 'node_js' project.Right?
