Upon building the project with tsc --project ./ I get the following error.

Found 1 error in node_modules/@alch/alchemy-web3/node_modules/@types/bn.js/index.d.ts:8

I understand this may be out of scope for this repo, but any help is appreciated.

I thought that this is due to dotenv package; and I reorganised my repo into a monorepo to have different dependencies and all that jazz, but after that I am again facing this error. This time, my package.json looks like below

"dependencies": {
    "@alch/alchemy-web3": "^1.4.4",
    "dotenv": "^16.0.1",
    "sturdy-websocket": "^0.2.1",
    "websocket": "^1.0.28"
  },
  "devDependencies": {
    "@typescript-eslint/eslint-plugin": "^5.30.3",
    "@typescript-eslint/parser": "^5.30.3",
    "eslint": "^8.19.0",
    "eslint-config-prettier": "^8.5.0",
    "eslint-plugin-prettier": "^4.2.1",
    "nodemon": "^2.0.18",
    "prettier": "^2.7.1",
    "ts-node": "^10.8.1",
    "typescript": "^4.7.4"
  }

And I am getting error for

 error TS4090: Conflicting definitions for 'node' found at '/Users/p/workspace/Back/node_modules/@alch/alchemy-web3/node_modules/@types/node/index.d.ts' and '/Users/p/workspace/Back/node_modules/@types/node/index.d.ts'. Consider installing a specific version of this library to resolve the conflict.

I am able to resolve the second error by adding following to my tsconfig.json

"typeRoots": [
      "types",
      "../../node_modules/@types" // Since this is a monorepo
    ]
