运行npm start时出现此错误

找不到模块'react-dev-utils / WebpackDevServerUtils'

我什至尝试删除并重新安装。有什么帮助吗？这是package.json

{
  "name": "tic-tac-toe-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.4.1",
    "react-dom": "^16.4.1",
    "react-router": "^4.3.1",
    "react-router-dom": "^4.3.1",
    "react-scripts": "1.1.4",
    "webpack": "^4.15.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "devDependencies": {
    "react-dev-utils": "^5.0.1",
    "react-scripts": "^1.1.4",
    "webpack": "^1.15.0",
    "webpack-cli": "^3.0.8",
