Cannot redeclare block-scoped variable 'addCommand'

[CanTheAlmighty]

Hi, I just moved from tedis to this library with very few issues, but I'm getting a compile time issue:

Cannot redeclare block-scoped variable 'addCommand'

To isolate the issue, I created an empty typescript project:

{
  "name": "crashy",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "dependencies": {
    "@types/node": "^15.14.0",
    "handy-redis": "^2.2.1",
    "redis": "^3.1.2",
    "typescript": "^4.3.5"
  }
}

With the above, the dependencies currently are (yarn.lock summarized):

// Format
// Package file : Installed Version
@types/redis@^2.8.27:  version "2.8.30"
redis@^3.1.2: version "3.1.2"
handy-redis@^2.2.1: version "2.2.1"

And used a very generic typescript config file.

With all of the above, I get the following conflict:

1410 export function addCommand(command: string): void;
                     ~~~~~~~~~~

  node_modules/handy-redis/dist/node_redis/index.d.ts:5:11
    5     const addCommand: (name: string) => void;
                ~~~~~~~~~~
    'addCommand' was also declared here.

I went to the DefinitleTyped repo (aka @types/redis) and there was this very interesting commit 8 days ago (since time of posting):

DefinitelyTyped/DefinitelyTyped@fa3bd98

• move add_command to correct location

This seems to be the source of the clash, as addCommand was moved from RedisClient.addCommand to a top-level function

Opened a PR: #311

same issue, I'll rolling back to handy-redis 1.8.3, waiting for a new version.

Alternatively, you can manually change yarn.lock and force it to keep the older version of the package
