Think it's ES module and works in import way, but you can do something like this:

Use ESM syntax, also use one of these methods before running the file.

1. specify "type":"module" in package.json
2. Or use this flag --input-type=module when running the file
3. Or use .mjs file extension

I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.

So, do this:

• In package.json, update the line "babel-eslint": "^10.0.2", to "@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
• Run npm i from a terminal/command prompt in the folder
• In .eslintrc, update the parser line "parser": "babel-eslint", to "parser": "@babel/eslint-parser",
• In .eslintrc, add "requireConfigFile": false, to the parserOptions section (underneath "ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
• Run the command to lint a file

Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.

From the node-fetch package readme:

node-fetch is an ESM-only module - you are not able to import it with require. We recommend you stay on v2 which is built with CommonJS unless you use ESM yourself. We will continue to publish critical bug fixes for it.

If you want to require it, then downgrade to v2.

The other option you have is to use async import('node-fetch').then(...)

Here's the response to the issue from the Framer Discord

regarding the issue with the current version of create-react-app (CRA) the issue is being tracked on GitHub here: https://github.com/formatjs/formatjs/issues/1395

After testing a bit it seems that the issue is with how CRA handles ESM dependancies and more particularly transitive dependancies are not handled correctly it seems. There is also an outstanding issue with CRA about this https://github.com/facebook/create-react-app/issues/10356.

Options:

1. This is fixed/doesn't break in the next version of CRA which you can try today (https://github.com/facebook/create-react-app/discussions/11278) take note though its still in alpha.

2. You can patch CRA to get around the issue as described in a number of tickets from other libraries

gulp-imagemin 8.0.0 and above are now ESM only. You can downgrade gulp-imagemin to 7.1.0 which is commonjs and it should work fine.

This package is now pure ESM. Please read this.

What is happening:

The function itemToForm() is being called before the this.item is ready.

There are many strategies to avoid this error. A very simple one is to add a catcher at the beginning of the function, like this:

I have solved it by forcing update flutter_math_fork adding to pubspec:

node-fetch v3 recently stopped support for the require way of importing it in favor of ES Modules. You'll need to use ESM imports now, like:
