And it should show some version information, and not indicate an error such as The term 'code' is not recognized

To verify that npm is installed, type

Troubleshooting

npm.ps1 cannot be loaded because running scripts is disabled on this system

When using Node v22 and greater, npm commands in PowerShell may throw a scripts disabled error.

You have 2 options.

1st option, you can run npm with the .cmd suffix, E.g,

npm.cmd -v
# or
npm.cmd run dev

or 2nd option, set the execution policy.

Set-ExecutionPolicy Unrestricted -Scope CurrentUser

TLS 1.2 or higher must be used when installing packages.

Since October 4, 2021, NPM versions on before version 7, will produce an error stating that TLS 1.2 or higher must be used when installing packages.

If you see TLS related errors when installing packages, try re-installing to the latest LTS version of Node.js by using the official download options on the Node.js website at https://nodejs.org/en/download/

Or, you could try upgrading to the latest version of NPM using the command line,

npm install -g npm

or (depending on your existing version of NPM)

npm install --location=global npm

Then test your version is at least version 7 or higher.

npm -v
#10.5.0

The problem exists since older versions of NPM (I.e., version 6.#.#) would contain registry settings using the http:// protocol, but now they must all be using the https:// protocol instead.
