Question

我对Express和Typescript都是全新的。我有继承一个使用express for API的项目。我需要做一些更改，但要开始，我甚至无法转换代码。在转向SO之前，我一直在试图寻找解决方案，但我在这里，所以请善待。

当我跑步时：

npm run tsc

我收到了许多与查找包相关的错误消息：

app/server.ts(2,26): error TS2307: Cannot find module 'express'.
app/server.ts(11,20): error TS2304: Cannot find name 'Promise'.
app/server.ts(30,22): error TS2304: Cannot find name 'require'.

这是我的package.json

{
"name": "my-backend",
  "version": "1.0.0",
  "description": "Express backend",
  "scripts": {
	"start": "node dist/server.js",
	"tsc": "tsc",
	"typings": "typings"
  },
  "keywords": [],

  "devDependencies": {
	"tslint": "^3.11.0",
	"typescript": "^1.8.10",
	"typings": "^1.3.0"
  }
}

这是我的tsconfig.js

{
    "compileOnSave": true,
    "compilerOptions": {
        "target": "es5",
        "declaration": false,
        "module": "commonjs",
        "moduleResolution": "classic",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false,
        "suppressImplicitAnyIndexErrors": true,
        "outDir": "dist/"
    },
    "exclude": [
        "node_modules"
    ]
}

我安装了所有正在运行的软件包：

npm install

NPM日志包含以下错误：

非常感谢任何指针/所需的阅读。
