Getting an error "Can't resolve 'os'"
I am using node v16.13.0
and Gatsby. This is what happens after I install parallel.js and imported it in my code. I am not really sure what the issue is.
import Parallel from 'paralleljs';
const p = new Parallel([0, 1, 2, 3, 4, 5, 6]);
const log = function () { console.log(arguments); };
ERROR #98124 WEBPACK
Generating development JavaScript bundle failed
Can't resolve 'os' in '/Users/hello/projects/example/yoyo/app/node_modules/paralleljs/lib'
If you're trying to use a package make sure that 'os' is installed. If you're trying to use a local file make sure that the path is correct.
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "os": require.resolve("os-browserify/browser") }'
- install 'os-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "os": false }
File: node_modules/paralleljs/lib/parallel.js:81:8
Not sure if that helps, but you can try installing this pollyfill.
run
npm install node-polyfill-webpack-plugin
then add the following to your config
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin');
module.exports = {
// Other rules...
plugins: [
new NodePolyfillPlugin()
]
};
