[BUG] Same package at multiple levels in bundleDependencies triggers NPM failures

[rix0rrr]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

If the same package is part of bundleDependencies at multiple levels in a dependency tree, NPM errors out during installation.

This can be observed during the installation of aws-cdk-lib@2.251.0, if that package is declared to be part of bundleDependencies:

// package.json
{
  "name": "cdk-bundled-deps-repro",
  "version": "1.0.0",
  "dependencies": {
    "aws-cdk-lib": "2.251.0"
  },
  "bundledDependencies": [
    "aws-cdk-lib"
  ]
}

And then

$ npm install
npm error code ENOENT
npm error syscall mkdir
npm error path <workdir>/node_modules/aws-cdk-lib/node_modules/@aws-cdk/cloud-assembly-api/node_modules/semver
npm error errno -2
npm error enoent ENOENT: no such file or directory, mkdir '<workdir>/node_modules/aws-cdk-lib/node_modules/@aws-cdk/cloud-assembly-api/node_modules/semver'

This is our dependency tree:

aws-cdk-lib -[bundles]-> jsonschema
            -[bundles]-> semver
            -[bundles]-> @aws-cdk/cloud-assembly-api -[bundles]-> jsonschema
                                                     -[bundles]-> semver

Expected Behavior

NPM should not throw ENOENT while making a directory:

return await mkdir(dest, { recursive: true })

Steps To Reproduce

Make the following package.json and run npm install:

// package.json
{
  "name": "cdk-bundled-deps-repro",
  "version": "1.0.0",
  "dependencies": {
    "aws-cdk-lib": "2.251.0"
  },
  "bundledDependencies": [
    "aws-cdk-lib"
  ]
}

And then

$ npm install
npm error code ENOENT
npm error syscall mkdir
npm error path <workdir>/node_modules/aws-cdk-lib/node_modules/@aws-cdk/cloud-assembly-api/node_modules/semver
npm error errno -2
npm error enoent ENOENT: no such file or directory, mkdir '<workdir>/node_modules/aws-cdk-lib/node_modules/@aws-cdk/cloud-assembly-api/node_modules/semver'
