This still happens.

The below snippet looks like a smaller reproduction of the same issue:

import shelljs from "npm:shelljs";
shelljs.exec("echo 1")

shelljs.exec tries to call child_process.execFileSync with shelljs/src/exec-child.js as an entrypoint, and it seems handled as ESM instead of CJS.

The issue seems disappearing if I use byonm settings (with package.json and node_modules)

[kt3k]

in_npm_package check of ManagedCliNpmResolver seems returning false in the above case.

In that check function, root_dir_url becomes file:///Users/kt3k/Library/Caches/deno/npm/registry.npmjs.org/shelljs/0.8.5/node_modules/ in the above situation, and that directory doesn't exist. So this check never returns true for any specifier in the above invocation..

Line 556 in 9f27bf9

let root_dir_url = self.fs_resolver.root_dir_url();

I guess probably there's some error in creating npm_cache_dir.root_dir_url?
