@angular-cli install fails with deprecated [email protected]: request has been deprecated (mac)

Question

After updating node.js and npm to current LTS:

node -v
v12.16.0

npm -v
6.13.4

When I'm trying to install @angular-cli following the steps in the documentation, running npm install -g @angular/cli in the terminal stops the installation and the console output is:

npm install -g @angular/cli
npm WARN deprecated [email protected]: request has been deprecated, see https://github.com/request/request/issues/3142
/Users/user/.npm-global/bin/ng -> /USERS/USER/.npm-global/lib/node_modules/@angular/cli/bin/ng

> @angular/[email protected] postinstall /USERS/USER/.npm-global/lib/node_modules/@angular/cli
> node ./bin/postinstall/script.js

+ @angular/[email protected]
updated 1 package in 12.202s

And in this case, ng new project-name yields -bash: ng: command not found. Any help would be very welcome as I have a big project coming up. Thanks all.

Answer 1

Unfortunately, Request package was deprecated. and that according to Mikeal Rogers (creator of request) read this link

Answer 2

The issue you are experiencing has noting to do with npm warning you see in console ref. It is seems more likely a problem with permissions on your machine or NodeJS installation issue or both.

I would recommend to remove your NodeJS installation completely at first and then install NVM to manage your NodeJS instances:

• Mac/Linux: https://github.com/nvm-sh/nvm
• Windows:https://github.com/coreybutler/nvm-windows

Once you done installing NVM try to install Angular CLI:

npm install @angular/cli -g

Hope it helps!

Answer 3

I removed "node_modules" folder & "package-lock.json" file and then execute following 2 commands:

npm init

npm install

And then, it worked properly.

Answer 4

I tried cleaning cache and it worked for me.

npm cache clean --force

Answer 5

The package request is now fully deprecated. So that will probably take a while to change. I think the solution would be for angular cli to release a new version that is not reliant upon request.
