Attempted import error: 'validate' is not exported from 'csstree-validator'.

[prathamesh-bigpi]

I have installed "csstree-validator": "^3.0.0", version and imported in react application
import { validate } from 'csstree-validator';
Trying to run it but getting following error
Attempted import error: 'validate' is not exported from 'csstree-validator'.
csstree_validator__WEBPACK_IMPORTED_MODULE_13__.default.validate is not a function

After changing import statement to import { validate } from 'csstree-validator/lib/validate'; the code is working fine. Is this a known issue ?

Note: version 2.0.1 is working fine.

Same issue, using csstree-validator@3.0.0, upgraded my webpack to version 5 and getting

Error: Module not found: Error: Package path ./dist/csstree-validator.js is not exported from package node_modules/csstree-validator (see exports field in node_modules/csstree-validator/package.json)

if using import { validate } from 'csstree-validator';,
getting this

./node_modules/csstree-validator/lib/helpers.js:2:0-37 - Error: Module not found: Error: Can't resolve 'path' in '/Users/kpavlenko/projects/communication-app/node_modules/csstree-validator/lib'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "path": require.resolve("path-browserify") }'
        - install 'path-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "path": false }

@prathamesh-bigpi if you are using webpack 4, this may help you(used to work for us before an upgrade)
import { validate } from 'csstree-validator/dist/csstree-validator.esm.js';

btw your solution does not work for me neither :(

Same issue here. It doesn't even work when I use require:

 [ERROR] Could not resolve "fs"

    node_modules/csstree-validator/cjs/helpers.cjs:3:19:
      3 │ const fs = require('fs');
        ╵                    ~~~~

  The package "fs" wasn't found on the file system but is built into node. Are you trying to bundle
  for node? You can use "--platform=node" to do that, which will remove this error.
