As bun sounds promising, I've been adapting it in my daily life for a better/alternative solution to npm.

The Pain

The pain But today I got error: IsDir in my new helloworld project for learning React.

Google search found nothing related, but a closed issue did help. - error: IsDir when running bun install #168 https://github.com/oven-sh/bun/issues/168

The Cause

so on install, bun looks for a plaintext .env file - https://github.com/oven-sh/bun/blob/c3bf97002d6f0b117060dabf2aa281eedd85b7fd/src/env_loader.zig and then tries to parse it. If .env is a folder, it will fall over.

The Fix

If you have a .env/ in your project root folder, rename or remove it. Bun will act normal now.
