NPM start throwing errors

Question

Hi I am trying to install and run angular-phonecat project.

1. install git ( windows ) from github
2. Opened git shell.cloned the probject.
3. I have node already installed so I opened node console and typed node --version.I got v0.10.9
4. back to git shell. did npm install in the angular-phonecat directory ( to install all dependencies as angular js suggests here: https://docs.angularjs.org/tutorial

I got following error then:

npm ERR! Error: No compatible version found: karma-chrome-launcher@'^0.1.4'

Answer 1

Open your package.json file and change "karma-chrome-launcher": "^0.1.4" with "karma-chrome-launcher": "0.1.4", that is, remove the caret. Same with all the dependencies that use that notation. You can see the meaning of the version numbers here.

https://www.npmjs.org/doc/files/package.json.html#dependencies

The ^ character means "Compatible with".

You can also try to upgrade node and npm, versions 0.10.9 and 1.2.24 are quite old now, and the ^ character is not supported in that version .

Caret was first available in npm from August 2013 and became the default save prefix 6 months later in February 2014.

Which is npm version 1.3.7.

If it still does not work try npm cache clear and then npm install again.

If your problem is the proxy you can try npm config set proxy and npm config set https-proxy as described here jjasonclark.com/how-to-setup-node-behind-web-proxy .

Hope this helps.

Note : I have tried npm install on a fresh copy of this repository myself and it works, although not Windows and versions 0.10.28 and 1.4.9 respectively. So the package.json is correct, strictly speaking.
