How to check currently installed web3 version?

Question

How to check installed web3 version with command line terminal?

This message has nothing to do with web3, it's telling you to upgrade npm itself. — goodvibration, Jun 12 '18 at 06:03

From a command line: npm ls web3 or npm list web3.

By the way, this message has nothing to do with web3, it's telling you to upgrade npm itself.

npm install web3 installs web3.js, which has a version command documented here: https://github.com/ethereum/wiki/wiki/JavaScript-API#web3versionapi

var version = web3.version.api;
console.log(version); // "0.2.0"

Update for 2020:

It's just Web3.version

E.g.

console.log(Web3.version);

You can check your node module versions using:

npm view <module> version

So just type on your terminal:

npm view web3 version

You may by the following:

Step-I: on your console write "node" and then enter

~/../currentDir> node

Then:

>var Web3 = require("web3");
>console.log(Web3.version);

Output:

'1.2.11' //version
