license-ls does not work with npm@7 and hangs forever

Using [email protected] with npm 7.19.0 does not work: it produces no output and does not terminate.

How to reproduce?

Simply run license-ls with npm@latest

Details

7.19.0

/ Analyzing

The spinner before Analyzing keeps spinning forever and you have to termine license-ls manually.

Error causes

The cuplrit seems to be that npm 7 changed the argument handling drastically:

...\license-ls> npm -v
6.14.13

...\license-ls> npm list --parseable --prod --depth=0 "--csv=[object Object]"
...\license-ls
...\license-ls\node_modules\cross-spawn
...\license-ls\node_modules\debug
...\license-ls\node_modules\glob
...\license-ls\node_modules\json2csv
...\license-ls\node_modules\jstoxml
...\license-ls\node_modules\lodash
...\license-ls\node_modules\ora
...\license-ls\node_modules\read-package-tree
...\license-ls\node_modules\spdx-expression-parse
...\license-ls\node_modules\spdx-license-list
...\license-ls\node_modules\table
...\license-ls\node_modules\yargs

...\license-ls>

...\license-ls>npm -v
7.19.0

...\license-ls>npm list --parseable --prod --depth=0 "--csv=[object Object]"
7.19.0

...\license-ls>

When license-ls is started with [email protected] npmList(...) returns ['7.19.0'] as package list. This in turn leads to a Error: ENOENT which is not handled and the spinner keeps spinning.

(The hang only occurs in an interactive TTY as ora does not animate the spinners when license-ls is started by other means)

I can confirm this:

Analyzingnode:internal/process/promises:245
          triggerUncaughtException(err, true /* fromPromise */);
          ^

[Error: ENOENT: no such file or directory, lstat '/home/ruben/dev/web/renewedtab/7.7.6'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'lstat',
  path: '/home/ruben/dev/web/renewedtab/7.7.6'
}

Is there any plan to fix this?
