ng new [project name] generates no polyfills.ts file

brianreinhold — Wed, 03 May 2023 10:38:10 +0000

I have created a few new angular projects using ng new. No polyfills.ts file is created. I have read that angular-cli supports polyfills so I assumed the file would be created.

Where do I get this file if ng new does not create it?

Angular Update Guide does not work

I am trying to update my angular project from 7 to 8 (eventually I want to update to the latest). Following the Angular Update Guide here https://update.angular.io/?v=7.2-8.2 gives the following error after invoking the first command instruction cmd /C "set "NG_DISABLE_VERSION_CHECK=1" && npx @angular/cli@8 update @angular/cli@8 @angular/core@8"

npm ERR! code EBADPLATFORM
npm ERR! notsup Unsupported platform for fsevents@2.3.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
npm ERR! notsup Valid OS: darwin
npm ERR! notsup Valid Arch: any
npm ERR! notsup Actual OS: win32
npm ERR! notsup Actual Arch: x64

and quits.

My package.json file is updated but package-lock.json is not. There is no help in the instructions about what to do when things go wrong. I have tried different variants and there are always conflicts - not in the code but the node-modules dependencies; usually conflicting angular dependencies.

How does one actually do this? Any help would be greatly appreciated!

npm install fails, ng serve works

I have been tasked with fixing and updating a complex Angular Cli project that is basically ancient. Everything for me is new here; javascript, typescript, node JS (npm), and of course, Angular itself.
After a week or two I have obtained some familiarity thanks to many excellent tutorial videos on You Tube.

But I have come across a perplexing problem I do not understand and cannot fix. I have the following for versions:

Angular CLI: 14.2.0
Node: 14.18.1
Package Manager: npm 6.14.18
OS: win32 x64

Angular: 7.2.16
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, router

Package                         Version
---------------------------------------------------------
@angular-devkit/architect       0.10.7
@angular-devkit/build-angular   0.10.7
@angular-devkit/core            0.3.2
@angular-devkit/schematics      14.2.0
@angular/cdk                    7.3.7
@angular/cli                    14.2.0
@angular/flex-layout            7.0.0-beta.19
@angular/material               7.3.7
@schematics/angular             14.2.0
rxjs                            6.5.5
typescript                      3.1.6

When I run npm install I get the following errors:

gyp ERR! UNCAUGHT EXCEPTION

gyp ERR!     <https://github.com/nodejs/node-gyp/issues>
Build failed with error code: 7

However, ng serve works!

I spent a week trying to get another version of node-gyp to be used, always failing and never tried ng serve because I assumed it would not work.

The goal is to update this project to the current versions of Angular cli / nodeJs but I am at a loss to understand the failure of 'npm install' and the success of 'ng serve'

What am I missing?
