🐛 BUG: Could not resolve errors when using WASM on Windows

See original GitHub issue

What version of `Wrangler` are you using?

0.0.0-859d6e7

What operating system are you using?

Windows

Describe the Bug

Whilst trying out the new WASI on workers, I was unable to use the new feature on Windows. I believe this is a Windows-specific issue, as it did not occur when using the exact same command with the exact same WASM file on WSL.

Windows NodeJS version: v16.15.0 WSL NodeJS version: v16.16.0

When running

npx wrangler@wasm dev target/wasm32-wasi/release/wasmtest.wasm

on Windows, it prints out the following error:

X [ERROR] Could not resolve "....\npm-cache_npxab8cfd027326cb55\node_modules@cloudflareworkers-wasidistindex.mjs"

    ../../../AppData/Local/Temp/tmp-31516-jZOY6EVYFut2/index.mjs:2:21:

        ╵                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  You can mark the path
  "....\npm-cache_npxab8cfd027326cb55\node_modules@cloudflareworkers-wasidistindex.mjs" as external
  to exclude it from the bundle, which will remove this error.

The root of the Rust project I used to test this is in C:\Users\zegevlier\Documents\code\wasmtest.

I also tried it in the root of the directory containing the .wasm file, but this also did not work and produced a similar error. This, again, worked perfectly as expected in WSL.
