  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;
      ^

  internal/modules/cjs/loader.js:611
      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?
