[BUG] Cannot find module '[...]/node_modules\node_modules\projen\bin\projen' if outdir without a subfolder in path

[jo-koe]

Describe the bug

When using awscdk.AwsCdkTypeScriptApp with an outdir without a subfolder e.g. just abc instead of subfolder/abc the below error is thrown during pdk build.

Expected Behavior

pdk build should succeed.

Current Behavior

pdk build fails with this error:

> nx run abc:build

$ D:\Users\XXX\Development\pdk-monorepo-issue\node_modules\.bin\projen build
abc: � build » post-compile » synth:silent | cdk synth -q

Reproduction Steps

1. Run `pdk new monorepo-ts``
2. Change .projenrc.ts to the following:

import { monorepo } from "@aws/pdk";
import { awscdk  } from 'projen';
const project = new monorepo.MonorepoTsProject({
  devDeps: ["@aws/pdk"],
  name: "pdk-monorepo-issue",
  projenrcTs: true,
});

new awscdk.AwsCdkTypeScriptApp({ 
  name: 'abc',
  outdir: 'abc',
  parent: project,
  cdkVersion: '2.131.0',
  defaultReleaseBranch: 'main',
});
project.synth();

3. Run pdk
4. Run pdk build

Hey @jo-koe,

Thanks for raising this! I've just tried your example and it seems to work for me!

I notice you're using Windows Server. Unfortunately we don't natively support Windows right now, but the recommended approach is to use WSL if you can.

We've got an issue open to add docs for this: #664

Thanks,
Jack

Hi @cogwirrel,

indeed Windows seems to be the problem here. I've switched to AMZ Linux now and it's working fine!

Cheers,
