Hello, I hope I can get a bit of help for a testing issue that has been nagging me…
I found a related issue but it is marked as closed so I assume I am missing something…
This is my package.js:
Package.describe({
name: 'sample-test-package',
version: '0.0.1',
// Brief, one-line summary of the package.
summary: '',
// URL to the Git repository containing the source code for this package.
git: '',
// By default, Meteor will default to using README.md for documentation.
// To avoid submitting documentation, set this field to null.
documentation: 'README.md'
});
Npm.depends({
github: '6.0.1'
})
Package.onUse(function(api) {
api.versionsFrom('1.4.2');
api.use('ecmascript');
api.mainModule('sample-test-package.js', 'server');
});
Package.onTest(function(api) {
api.use('ecmascript');
api.use('practicalmeteor:mocha');
api.use('sample-test-package');
api.mainModule('sample-test-package-tests.js', 'server');
});
And my test file is just this (my sample-test-package.js is the same):
import github from 'github'
But I get this error when running test with meteor test-packages --driver-package sample-test-package:

I looked in the built file and the ./error module is being imported from inside of the github module:
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// //
// node_modules/meteor/local-test:sample-test-package/node_modules/github/lib/index.js //
// //
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
//
"use strict";
var error = require("./error");
If I remove the import line then it works fine. Also in production it works fine. And if I change the “server” to “client” in package.js it seems to work fine too, though I don’t understand why as the built file seem similar, but obviously I don’t know enough about the Meteor build process 
I would appreciate any help.
