Hello i'm following a browser brain.js script's example and this is the example code:
<script src="brain-controller.js"></script>
<script>
net = new brain.recurrent.LSTM()
net.train([
'doe, a deer, a female deer',
'ray, a drop of golden sun',
'me, a name I call myself',
])
output = net.run('doe') // ', a deer, a female deer'
console.log(output)
</script>
brain-controller.js is the brain.js script updated, so please, DON'T USE CDNJS SCRIPT!!! It is bad! So this is bad too and doesn't works well. I can't run brainjs script in nodejs it gives me this error:
TypeError: Cannot read property 'LSTM' of undefined

When I do npm install brain.js it gives me those errors:

What I should do???
You must have the library imported incorrectly. You can see here your code works using the CDN. Specify the number of iterations (the default is 20,000 (see here)) and/or error threshold for faster performance.
function test() {
net = new brain.recurrent.LSTM()
net.train([
'doe, a deer, a female deer',
'ray, a drop of golden sun',
'me, a name I call myself',
], {
iterations: 1500,
log: details => console.log(details),
errorThresh: 0.011
});
output = net.run('doe') // ', a deer, a female deer'
const myOutput = document.querySelector('#myOutput');
myOutput.innerHTML = output;
console.log(output)
}
test();<script src="//unpkg.com/brain.js"></script>
<div id=myOutput></div>
