I installed Node.js using installer and angular cli using using cmd command. But I can't create a new project(ng new project-name) Please help me to resolve this. Thanks in advance

Had the same problem. Apparently npm just didn't have access to these packages, which was why it didn't find them. The following did it for me:

sudo ng new firstapp

The problem with our enviornment was that the version of node we were using was incompatible. We had v19 and it needes 10.13.x/12.11.x or later minor. See this referenced chart.

I face the same issue and but I solve it with the following steps

1- I install the latest node version from https://nodejs.org/en/

2- uninstall the cli by the following command

npm uninstall @angular/cli -g

3- clean the cache by the following command

npm cache clean --force

& verify by

npm cache verify

4- now run the following command

npm install -g @angular/cli

5- now created new project.It worked for me

Workaround

There is a workaround for starting a new Angular project:

ng new project --skip-install

cd project

npm install (or if that fails npm install --force)

I discovered this within the comments of the open issue for this error on angular-cli github repo which Ammar M Mashfj linked to in their answer: https://github.com/angular/angular-cli/issues/20719#issuecomment-835810313

I had a similar error, so I chose a newer node version using n library, like here: https://nkaushik.com/nodejs/nodejs-version-manager-n/

then I updated my angular version with :

install -g @angular/cli

oh, and don't forget to turn off your VPN

Check this, it's the same issue.

Open the folder you create with ng new and open the package.json file. In devDependencies change the version of "jasmine-core" 3.6.0 to 3.7.1 and "karma-jasmine-html-reporter" from 1.5.0 to 1.6.0 and save it. Than go back to Terminal and go to your project and run npm install. Now it works und you can run ng serve.

you can also Downgrade npm from 7 to 6 using npm install -g npm@6 to fix this probleme

if you have another problem during the instalation, delete npm and npm-cache in: \AppData\Roaming and try again

this is an error in angular-cli by some outdated packages , it has been solved in their repository in github , but they haven't published it yet to npmjs , you can solve it in 2 ways:

  1. using "--legacy-peer-deps --force" when installing packages
  2. updating package.json at "jasmine" like in the latest commit in https://github.com/angular/angular-cli/commit/b34ed5c4007f9ef08b370219081b4d23f9f24fb8

this is an open issue for this error on angular-cli github repo https://github.com/angular/angular-cli/issues/20719
