gulp task issue with nodejs v10.3.0 : src\node_contextify.cc:629: Assertion `args[1]->IsString()' failed

I recently updated my nodejs version to 10.30.0. Everything works fine. But my gulp build task not working which was working fine on older version(9.X). This is what I am getting.

 gulp[11376]: src\node_contextify.cc:629: Assertion `args[1]->IsString()' failed.
 1: node::DecodeWrite
 2: node::DecodeWrite
 3: uv_loop_fork

Somebody, please help me.

Just run command

npm install natives

I have had two different solutions work in two different workspaces. The first after updating to node 10.6.0 required me to use this method:

$rm -rf node_modules
$rm -rf package-lock.json
$npm cache clean
$npm install

The second workspace wouldn't work with the above, though I did try it first, it required me to reinstall all my gulp dependencies then run npm audit fix. For example:

$npm install --dev gulp gulp-sass gulp-autoprefixer
$npm audit fix

Hope this helps someone.

node version compatible problem, try use node version<=9.11.2.

I had the same issue. Deleting node_modules and re-running npm install, to re-install the modules listed in package.json, did work for me.

Just run these two commands.

1. remove node_modules folder

> rm -r node_modules

2. And Install only natives dependencies.

> npm install natives

npm install natives

This works with Windows 10 64 Bit

My system:

1. Windows 10
2. Node 10.15.3

Steps:

1. npm update
2. npm i natives
3. npm i
4. npm audit fix

The order is required.

I was facing similar problem too with gulp

gulp build[30580]: c:\ws\src\node_contextify.cc:635: Assertion `args[1]->IsString()' failed. 1: 00007FF6F86BC6AA v8::internal::GCIdleTimeHandler::GCIdleTimeHandler+4506

npm install natives solved the problem in windows 64

using node v10.16.0

npm install natives

npm audit fix

npm (not yarn) solution

1. Update your npm packages
2. npm rebuild // Install will likely work too?
3. You'll likely get a new error about 'parallels'
4. Follow this guide (not mine): https://timonweb.com/javascript/how-to-fix-referenceerror-primordials-is-not-defined-error/

Why? Gulp v3 + Node v12 are incompatible with each other. Don't try updating to Gulp v4 for the purpose of fixing this issue, as there are breaking changes (unless you wanna rewrite your code). Don't downgrade Node because it's not scalable and you may run into other issues. You'll have to upgrade eventually.
