  npm_config_argv` is not officially documented so here are our research notes

`npm_config_argv` is available to the postinstall script when the containing package has been installed by npm into some project.

An example of its value:

```
  npm_config_argv: '{"remain":["../test"],"cooked":["add","../test"],"original":["add","../test"]}',
  ```

We are interesting in the data contained in the "original" field.

Trivia/Note: `npm_config_argv` is not available when running e.g. `npm install` on the containing package itself (e.g. when working on it)

Yarn mimics this data and environment variable. Here is an example following `yarn add` for the same package:

```
  npm_config_argv: '{"remain":[],"cooked":["add"],"original":["add","../test"]}'
  ```

Other package managers like `pnpm` have not been tested.
