I ran into the same problem. Fixed this by downgrading from 1.1.2 to 1.1.1

I think the problem is that bundle.js and bundle-esm.js are mismatched here

danfojs/src/danfojs-browser/package.json

Line 7 in fe37f10

"module": "lib/bundle-esm.js",

danfojs/src/danfojs-browser/webpack.config.js

Line 15 in a8d14d4

filename: "bundle.js",

This would be the breaking change

I have made a PR to address this #516

Thanks @pensono, in version 1.1.1 everthing works fine!

I had the same problem, instead of rolling back to old version, you can also change the import statement to import the file directly from where it is defined instead of importing it from main module. For example if you want to use DataFrame-

This doesn't work

import { DataFrame } from 'danfojs';

But, this will work:

import { DataFrame } from 'danfojs/dist/danfojs-base'

You can use this as a workaround until the package.json file is fixed on main

May I ask if this issue has been resolved?

It seems not to be. If you look in the npm-hosted package contents, the command build:esm-bundle in package.json is there to build the esm module, but the package that gets published is missing the necessary lib/bundle-esm.js file. I don't know what sort of publishing workflow there is, but it seems that running build:esm-bundle is overlooked in the process.
