Cannot create LSTM network in brain.js

[GA-VI]

After installing brainjs on an Apple Mac using the Terminal command:

npm install brainjs

I find the following attempt in node.js to create an LSTM network results in an error:

const brain = require('brainjs');

const net = new brain.recurrent.LSTM();

The error message shown in Terminal is:

const net = new brain.recurrent.LSTM();
                                ^
TypeError: Cannot read properties of undefined (reading 'LSTM')

What am I doing wrong here?

I am following code example articles here and here.

@GA-VI , you have a little typo. brain.js not brainjs, that should resolve this for you.

Thanks very much for your post. I am actually using brainjs which is a fork of brain.js.

This is because when I try to install brain.js using the command npm install brain.js I get the following error:

npm WARN deprecated @npmcli/move-file@2.0.1: This functionality has been moved to @npmcli/fs

I can't figure out how to successfully install brain.js using the npm command.

Whereas I can successfully install the brainjs fork using npm. It's possible I guess that the brainjs fork does not offer LSTM networks.
