node.js - npm start 在 CRA "with no error"中不起作用

Question

node 12.13.1

npm 6.13.1

npm i -g create-react-app

create-reap-app appName

cd appName

npm start

并且没有错误显示，只是 vscode 转到下一行，奇怪的是我没有错误。删除了几乎所有 git node 并重新安装了它们，但仍然无法正常工作。只需转到下一行即可。这个问题到底从何而来？谢谢。

// package.json

{
  "name": "tested",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "react-scripts": "3.2.0"
  },
  "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"
    ]
  }
}

检查npm配置列表并查看ignore-script是否设置为true。

将其全局和本地更改为 false。
