Upgrade to gulp 4 (Fix "ReferenceError: primordials is not defined" when running "npm run build")

[ndbroadbent]

$ npm run build

> [email protected] build /Users/me/code/alpaca
> gulp default

fs.js:27
const { Math, Object } = primordials;
                         ^

ReferenceError: primordials is not defined
    at fs.js:27:26

I found this StackOverflow answer:

I suspect you're using node 12 and gulp 3. That combination does not work: gulpjs/gulp#2324
...
Solution: Either upgrade to gulp 4 or downgrade to an earlier node.

So I would like to request an upgrade to gulp 4, or alternatively add some docs about supported Node versions. Thank you!

I can confirm this problem. However, upgrading to gulp 4 solves this issue but creates another issue, considering Alpaca was not written for gulp 4.

Alpaca needs to be updated, but I believe it is no longer being maintained.

Hello, i had the same problem.
To resolve it, you have to downgrade node.js or do add a file npm-shrinkwrap.json in the source with the following code :
{ "dependencies": { "graceful-fs": { "version": "4.2.2" } } }

Then : npm install
