Build error when installing on travis

[tomoakley]

Hi, I'm getting a build error when installing libpq on Travis - specifically node-gyp rebuild. I'm not using pq-native or libpq directly; I'm using Sequelize and Postgres, which I guess implements your packages. Here is the error:

make: Leaving directory `/home/travis/build/tomoakley/xysti/node_modules/libpq/build'

I'm a bit of a newbie to devops/CI so not really sure what you want or need to see to help debug the issue, but happy to provide any info from Travis or my build/code. It's failing on all versions of Node which I have Travis set up to run (0.12, 5, 6, 6.1, stable).

Pretty sure I should be using Docker to do this, however I'm currently just pushing my code to Github which Travis is picking up to run the build; when running the production build locally I see no errors related to libpq. I will go and set up a Docker container and update this issue if I see any differences.

Before the errors above, there is also about 500 additional lines of logging - I can post this if it's useful but they aren't marked as errors by npm so I'll leave it out for now.

In my .travis.yml file I have Postgres set up:

language: node_js

node_js:
  - "0.12"
  - "5"
  - "6"
  - "6.1"
  - "stable"

sudo: required
dist: precise
addons:
    postgresql: "9.5"
services:
    - postgresql

script:
  - npm run lint
  - npm test

Can you provide the npm-debug.log file?
