回答1:
I just spend way to long with this issue. I'm not sure how it got set, perhaps during an install, but I changed a System Variable:
Name: ComSpec Value: %SystemRoot%\system32\cmd.exe;prefix=C:\Program Files (x86)\nodejs\node.exe
To this:
Name: ComSpec Value: %SystemRoot%\system32\cmd.exe
And restarted my system and the issue was gone.

@selva, For start some server with npm, you can use
npm start
A package can be downloaded with the command
npm install <package_name>
For install globally use -g after package name.
If there is no package.json file in the local directory, the latest version of the package is installed.
If there is package.json file, the latest version satisfying the semver rule declared in package.json for that package (if there is any) is installed.
npm only, does not anything. The command wait for something to do, install, help, etc.
If the problem with command npm --v continuous, try uninstall and install again.
Check this solution:
I saw your problem is with npm-cli, You need to Add C:\Program Files\nodejs to your PATH environment variable. To do this follow these steps:
Go to control panel -> System -> Advanced System Settings then environment variables.
- Use the global Search Charm to search "Environment Variables"
- Click "Edit system environment variables"
- Click "Environment Variables" in the dialog.
- In the "System Variables" box, search for Path and edit it to include
C:\Program Files\nodejs. Make sure it is separated from any other paths by a;. You will have to restart any currently-opened command prompts before it will take effect.
