npm 错误：缺少脚本：在尝试运行我的 React 应用程序时启动

Question

错误是 -

npm ERR! missing script: start

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\mattj\AppData\Roaming\npm-cache\_logs\2020-10-09T07_53_19_254Z-debug.log

但是我已经检查了我的 package.json 并且“开始”脚本就在那里。

{
  "name": "gmcb-react",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-scripts": "3.4.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我是 React 的新手，所以有没有我应该在 npm 开始之前运行的命令？ 我试过先运行 npm init 但无济于事。

在运行脚本之前确保你在正确的文件夹中

您可以通过终端命令cwd检查您所在的文件如果您不在正确的文件夹中，请确保您与 package.json 位于同一文件夹中
