Mastering resolving dependency issues

Question

I'm trying to set up project from my working computer on my home one. But due to fixed dependency versions something going wrong.

Here is my dependencies:

  "dependencies": {
    "@nestjs-modules/mailer": "2.0.2",
    "@nestjs/common": "10.0.0",
    "@nestjs/config": "3.2.3",
    "@nestjs/core": "10.0.0",
    "@nestjs/jwt": "10.2.0",
    "@nestjs/platform-express": "10.0.0",
    "@nestjs/swagger": "7.3.1",
    "@nestjs/typeorm": "10.0.2",
    "bcrypt": "5.1.1",
    "bcryptjs": "2.4.3",
    "class-transformer": "0.5.1",
    "class-validator": "0.14.1",
    "dotenv": "16.4.5",
    "mysql2": "3.10.2",
    "nodemailer": "6.9.14",
    "pg": "8.4.0",
    "reflect-metadata": "0.1.13",
    "rxjs": "7.8.1",
    "typeorm": "0.3.20"
  },
  "devDependencies": {
    "@nestjs/cli": "10.0.0",
    "@nestjs/schematics": "10.0.0",
    "@nestjs/testing": "10.0.0",
    "@types/express": "4.17.17",
    "@types/jest": "29.5.2",
    "@types/node": "16.11.10",
    "@types/supertest": "6.0.0",
    "@typescript-eslint/eslint-plugin": "6.0.0",
    "@typescript-eslint/parser": "6.0.0",
    "eslint": "8.42.0",
    "eslint-config-prettier": "9.0.0",
    "eslint-plugin-prettier": "5.0.0",
    "jest": "29.5.0",
    "prettier": "3.0.0",
    "source-map-support": "0.5.21",
    "supertest": "6.3.3",
    "ts-jest": "29.1.0",
    "ts-loader": "9.4.3",
    "ts-node": "10.9.1",
    "tsconfig-paths": "4.2.0",
    "typescript": "4.5.2"
  },

and error is:

When I'm updating TypeScript version there are new errors:

node_modules/@types/superagent/types.d.ts:14:32 - error TS2304: Cannot find name 'URL'.

14 export type URLType = string | URL | UrlObject;
                                  ~~~

node_modules/@types/supertest/types.d.ts:9:7 - error TS2315: Type 'RequestListener' is not generic.

9     | RequestListener<typeof IncomingMessage, typeof ServerResponse>
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

What should I do?

Answer 1

update your typeescript and types/node to latest. if it still doesn't work then run below

npm install --legacy-peer-deps

if this also doesn't work then undo all the changes, and forcefully install each dependency using --force flag. it would work perfectly
