Can't npm install a module packed with ncc on Windows

[pmhpereira]

Hello all,

Using vercel/ncc 0.36.0, I'm running into an odd issue that happens on Windows.

Running ncc build src/index.ts -o dist generates a dist/index.js file that starts with:

#!/usr/bin/env node
/******/ (() => { // webpackBootstrap
/******/ 	var __webpack_modules__ = ({

/***/ 83633:
/***/ ((module, __unused_webpack_exports, __nccwpck_require__) => {

...
rest of the file

If I try to npm i -g this module and then run it directly from console, it fails with some syntax errors.
Opening the generated scripts from the npm i -g command, shows that it contains the string /******/ (() => { // webpackBootstrap that shouldn't be there:

#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

case `uname` in
    *CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;;
esac

if [ -x "$basedir/node
/******/" ]; then
  exec "$basedir/node
/******/" (() => { // webpackBootstrap "$basedir/node_modules/@my-lib/cli/dist/index.js" "$@"
else 
  exec node
/******/ (() => { // webpackBootstrap "$basedir/node_modules/@my-lib/cli/dist/index.js" "$@"
fi

If you notice, it is the same string as the 2nd line of dist/index.js.

Any guidance on how to solve this is appreciated.

Thanks!

This is the same issue as #845. You can solve it manually by adding a blank line between the #!/usr/bin/env node and the rest of the generated code.
