Version 2: Couldn't find preset about webassets

[michaeltoohig]

I'm also having trouble setting up Babel for the first time and seeing the same error.

Any news on this?

I managed to fix this in the following way:

Install the following packages globally with npm install -g @babel/[email protected] @babel/[email protected]
├── @babel/[email protected]
├── @babel/[email protected]

For local npm packages, install "@babel/preset-env": "^7.20.2"

Them in python, for Flask-assets 2.0 and webassets 2.0, do.

from flask_assets import Bundle
from webassets.filter import get_filter
import os

babel = get_filter(
    "babel",
   extra_args=[
       "--plugins",
       "./<project_name>/static/vendor/node_modules/@babel/plugin-transform-spread",
   ]
)

Change the path accordingly. In my case the issue was with plugin-transform-spread that has also been included inside @babel package.

from webassets.
