Error [ERR_REQUIRE_ESM]: Must use import to load ES Module when running Alex

[adrhumphreys]

Subject of the issue

On a fresh install I'm getting these node issues with ES Imports, I haven't set up a config file and I can get these issues by creating a new repo

Your environment

• OS: OSX BigSur
• Packages: "alex": "^9.1.0"
• Env: Node v16.11.1 and Yarn 1.22.5

Steps to reproduce

1. mkdir alex && cd alex
2. yarn init -y
3. Add to package.json

   "scripts": {
   "lint": "alex"
   }

4. Run yarn lint

Expected behaviour

Linting occurs

Actual behaviour

I get this funky error

$ alex
/Users/username/Code/alex/node_modules/alex/cli.js:12
var mdx = require('remark-mdx')
          ^

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/username/Code/alex/node_modules/remark-mdx/index.js from /Users/username/Code/alex/node_modules/alex/cli.js not supported.
Instead change the require of index.js in /Users/username/Code/alex/node_modules/alex/cli.js to a dynamic import() which is available in all CommonJS modules.

  code: 'ERR_REQUIRE_ESM'
}
