npm run test on Windows fails

[hamishwillee]

What type of issue is this?

Infrastructure issue

What is the issue?

This is the error in cmd prompt:

> @mdn/browser-compat-data@7.3.0 unittest
> NODE_ENV=test c8 mocha index.test.ts --require tsx --recursive "{,!(node_modules)/**}/*.test.ts"

'NODE_ENV' is not recognized as an internal or external command,
operable program or batch file.

What behavior were you expecting?

Being able to run tests.

What version(s) of BCD is the issue present in?

• The current BCD release
• The current version of the main branch

Do you have anything more you want to share?

No response

Can you remind me what your current setup is? What shell are you using?

I justed tested with Git Bash and nvm on Windows 11 (ARM), and npm ci itself failed:

$ npm ci

Windows 11, intel, CMD prompt.

I wanted to retest so I pulled main and got similar error
