React& Typescript：启动开发服务器时出错

Question

我试图使用命令创建一个新的 typescript-react 项目

npx create-react-app todo-list --template typescript

安装进行得很顺利，但是当我运行该项目时

npm start

我遇到以下错误

PS C:\Users\ayex\Desktop\freecodecamp\React&Typescript\todo-list> npm start

> [email protected] start
> react-scripts start

'Typescript\todo-list\node_modules\.bin\' is not recognized as an internal or external command,
operable program or batch file.
node:internal/modules/cjs/loader:998
  throw err;
  ^

Error: Cannot find module 'C:\Users\ayex\Desktop\freecodecamp\react-scripts\bin\react-scripts.js'
    at Module._resolveFilename (node:internal/modules/cjs/loader:995:15)
    at Module._load (node:internal/modules/cjs/loader:841:27)

    at node:internal/main/run_main_module:23:47 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

Node.js v18.12.1

从错误消息中您可以清楚地看到它正在尝试查找react-scripts文件，但在错误的目录中，我不知道如何解决这个问题。我尝试删除

node_modules

和

package-lock.json

文件并运行

npm install

最终没有缺少。 这是package.json文件

  "name": "todo-list",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.17.0",

在 package.json 文件中添加类型模块。

{
  "name": "todo-list",
  "version": "0.1.0",
  "private": true,
  "type": "module"   
  "dependencies": {
    "@testing-library/jest-dom": "^5.17.0",
    "@testing-library/react": "^13.4.0",
    "@testing-library/user-event": "^13.5.0",
    "@types/jest": "^27.5.2",
    "@types/node": "^16.18.39",
    "@types/react": "^18.2.18",
    "@types/react-dom": "^18.2.7",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "typescript": "^4.9.5",
    "web-vitals": "^2.1.4"
  },
  "scripts": {
    "start": "react-scripts start",

    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {

      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
