This tutorial shows multiple ways to know the installed node and npm version. You can also check other posts on npm command deprecate option is deprecated

#How to get Node and npm versions in the command line

Open the terminal, type below command node --version or node -v

C:\>node --version
v14.17.0

node —version gives nodejs version installation number.

If you got the below error, node: command not found without a print version number, Then the probable cause is that nodejs is installed with the correct version or node path is not correctly set in environment variables.

-bash: node: command not found

And,npm is a node package manager that installs automatically with nodejs installation Run the below command to get the npm version.

C:\>npm --version
7.11.1
C:\>npm -v
7.11.1

Another way is to get the node version in javascript programming.

A process is a global object in Nodejs, versions property returns an object of versions

Create a main.js

console.log(process.versions)

Running node main.js output below versions It contains node attribute with version

{
node: '14.17.0',
v8: '8.4.371.23-node.63',
uv: '1.41.0',
zlib: '1.2.11',
brotli: '1.0.9',
ares: '1.17.1',
modules: '83',
nghttp2: '1.42.0',
napi: '8',
llhttp: '2.1.3',
openssl: '1.1.1k',
cldr: '38.1',
icu: '68.2',
tz: '2020d',
unicode: '13.0'
}

Another property process.version gives the node version

console.log(process.versions)

Similarly, you can get the node version using the command line with REPL. REPL is Read-Eval-Print-Loop interactive terminal to get nodejs process and execute node commands

Type node in terminal to change to REPL mode

node

Type process.versions in the terminal

process.versions
