Travis CI build failing

[aadityakulkarni]

It looks like Travis CI build is failing. I have seen a couple of pull requests where build failed for the same error as below:

`1.26s$ npm test

moment-timezone@0.5.17 test /home/travis/build/moment/moment-timezone
grunt
/home/travis/build/moment/moment-timezone/node_modules/grunt/node_modules/grunt-legacy-log/node_modules/grunt-legacy-log-utils/node_modules/chalk/index.js:2
const escapeStringRegexp = require('escape-string-regexp');
^^^^^
SyntaxError: Use of const in strict mode.`

Following is the link to my PR where the build failed:
Travis build

Can someone take a look and help me with this?

@aadityakulkarni just use var there instead of const

[aadityakulkarni]

Hi @ellenaua - Actually it's not me. It seems grunt uses npm package "chalk" which uses const instead of var and that is causing the build to fail.

/home/travis/build/moment/moment-timezone/node_modules/grunt/node_modules/grunt-legacy-log/node_modules/grunt-legacy-log-utils/node_modules/chalk/index.js:2 const escapeStringRegexp = require('escape-string-regexp'); ^^^^^ SyntaxError: Use of const in strict mode.

The following PR and its corresponding build also had the same issue:

PR: #622
