--- BEGIN ISSUE ---
cspell hook install fails due pre-commit assumptions regarding npm packages
I am raising this bug here as cspell is still unusable as a pre-commit hook even after the author made additional changes and I am afraid that the root cause is no longer inside cspell package.

Mainly cspell is a typescript project that is published on npm and you cannot run it without building it first. Apparently pre-commit does not know about this concenpt (or I am not aware about it).'

More information can be found on https://github.com/Jason3S/cspell/issues/53#issuecomment-402562237

To enabled cspell hook it should be enough to add this:
```
  - repo: https://github.com/Jason3S/cspell.git
    rev: v3.2.2
    hooks:
      - id: cspell
```

Still, once you run pre-precommit you soon endup with something like:
```
cspell...................................................................Failed
hookid: cspell

internal/modules/cjs/loader.js:611
    throw err;
    ^

    throw err;
    ^
```

The maintainer of cspell mentioned that the project was not designed to run from source, and the expected behavior is to install the npm package. I have to say that I kinda agree with his view.

How can we address this issue?
