Travis CI为什么不使用NODE_ENV生产运行“ npm install”

Question

I tried to compile my project in Travis CI with the following config:

language: node_js
node_js:
  - 0.12
env:
  global:
    - NODE_ENV=production
before_install:
  # - npm run init
before_script:
  # - bower install
  # - gulp
  # - npm install
script:
  - npm install -g bower
  - npm install -g gulp
  - gulp
  - npm run lint
sudo: false

If I set in my config

- NODE_ENV=production

Then Travis CI will compile my project.

Travis CI does run npm install automatically — I suspect the problem you're having is with NODE_ENV and dependencies and devDependencies .

If NODE_ENV=production , NPM will not install devDependencies (as noted here: https://github.com/npm/npm/issues/6803 ). You need to make sure the dependencies you need are in the correct group:

• NODE_ENV=production : dependencies installed from dependencies group
• NODE_ENV=development : dependencies installed from devDependencies group
