Question

Hello guys I went through all solution avaialble on stackoverflow. But none of work for me. Hence posting question. tsconfig.json

{
  "version":"2.13.0",
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": true,
    "noImplicitAny": false    
  },
  "exclude": [
        "node_modules"
    ]
}

package.json

{
  "name": "anguapp",
  "version": "1.0.0",
  "description": "Angular2 Gulp Typescript and Express",
  "main": "dist/server.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "postinstall": "gulp build"
  },
  "keywords": [],

  "license": "MIT",
  "dependencies": {

Please help me to solve these TS2304: Cannot find name 'Promise' errors

Answer 1

You just need to change your target to es6 inside your tsconfig.json to resolve this issue.

{
  "version":"2.13.0",
  "compilerOptions": {
    "target": "es6", //<- change here
    ......
  },
  "exclude": [
        "node_modules"
    ]
}

---

Other way what you can do is, you need to make sure you have es6-shim.js have been referred there on page and then follow this answer that would not need to change target option.
