在 Firebase 项目中将 typescript 升级到 4.1

Question

我想将 typescript 升级到 4.1 版，因为它是 adds support to template literal types。

但是，当我在函数目录中运行npm i typescript 时，它并没有升级到“^3.9.10”以上。

package.json：

{
  "name": "functions",
  "scripts": {
    "lint": "eslint \"src/**/*\"",
    "build": "tsc",
    "serve": "npm run build && firebase emulators:start --only functions",
    "shell": "npm run build && firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "12"
  },
  "main": "lib/index.js",
  "dependencies": {
    "@firecode/admin": "^0.8.2",
    "axios": "^0.21.4",
    "cors": "^2.8.5",
    "exegesis": "^3.0.1",
    "express": "^4.17.1",
    "firebase-admin": "^9.12.0",
    "firebase-functions": "^3.15.7"
  },
  "devDependencies": {
    "@typescript-eslint/eslint-plugin": "^3.9.1",
    "@typescript-eslint/parser": "^3.8.0",
    "eslint": "^7.32.0",
    "eslint-plugin-import": "^2.22.0",
    "firebase-functions-test": "^0.2.0",
    "typescript": "^3.9.10"
  },
  "private": true
}

tsconfig.json：

{
  "compilerOptions": {
    "module": "commonjs",
    "noImplicitReturns": true,
    "noUnusedLocals": true,
    "outDir": "lib",
    "sourceMap": true,
    "strict": true,
    "target": "es2017"
  },
  "compileOnSave": true,
  "include": [
    "src"
  ]
}

谢谢！

试试npm install -g typescript@latest。您也可以使用 npm update 代替 install，无需最新的修饰符。
