NG_DISABLE_VERSION_CHECK wasn't available in Angular versions before version 9. Support for Angular versions earlier than 15 has been discontinued. For more information, refer to: https://angular.io/guide/releases#actively-supported-versions

[Quentigus]

All previous versions automatically download lastest version (v17.0.9) and this version doesn't support the flag.
Node version testing is in the ng.js file.

How can I disable node version check on latest cli?

[alan-agius4]

NG_DISABLE_VERSION_CHECK can be used to disable the node.js check on the latest version (version 17), however the problem is that you are using Angular CLI version 7 in your project were this functionality was not available.

What you can do is following;

Disable the below check in node_modules/angular/cli/commands/update-impl.js

angular-cli/packages/angular/cli/commands/update-impl.ts

Line 44 in 6fb6b55

if (await this.checkCLILatestVersion(options.verbose, options.next)) {

and run the update using:

ng update @angular/common@8 @angular/cli@8 --allow-dirty --force --verbose

I've tested the migration with the flag and latest release (17.0.10).

The Node error is shown from this line :
https://github.com/angular/angular-cli/blob/17.0.10/packages/angular/cli/bin/ng.js#L60
