任务未找到："react-scripts:start"。

Question

我已经将tailwind.css配置到我的React项目中，并根据需要编辑了React脚本。

"scripts": {
    "build:css": "postcss src/styles/index.css -o src/styles/tailwind.css",
    "watch:css": "postcss src/styles/index.css -o src/styles/tailwind.css --watch",
    "react-script:start": "timeout <5>  && react-scripts start",
    "start": "run-p watch:css react-scripts:start",
    "build": "run-s build:css react-scripts:build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },

同时，这些相关的软件包已经被成功安装。我附上了 package.json 文件。

{
  "name": "myblog",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.4",
    "@testing-library/react": "^12.1.4",
    "@testing-library/user-event": "^13.5.0",
    "react": "^18.0.0",
    "react-dom": "^18.0.0",
    "react-scripts": "^5.0.0",
    "web-vitals": "^2.1.4"
  },
  "scripts": {
    "build:css": "postcss src/styles/index.css -o src/styles/tailwind.css",
    "watch:css": "postcss src/styles/index.css -o src/styles/tailwind.css --watch",
    "react-script:start": "timeout <5>  && react-scripts start",
    "start": "run-p watch:css react-scripts:start",
    "build": "run-s build:css react-scripts:build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "autoprefixer": "^10.4.4",
    "npm-run-all": "^4.1.5",
    "postcss": "^8.4.12",
    "postcss-cli": "^9.1.0",
    "tailwindcss": "^3.0.23"
  }
}

我不断地看到"任务未找到"的错误提示。

终端显示的错误信息

我尝试过以下方法：

1. 手动重新安装所有依赖项
2. 更改React脚本命令后执行npm install
3. 删除node模块并重新安装
4. 检查所有React脚本并运行npm-run-all

您的scripts部分存在拼写错误：

"start": "run-p watch:css react-scripts:start"寻找的是"react-scripts:"（复数形式，带有一个"s"），但是您的脚本名称不包含那个"s"（"react-script:"）。

  "scripts": {
    ...
    "react-script:start": "timeout <5>  && react-scripts start",
                 ^--- Does not contain the "s" - change this to: "react-scripts:start": "timeout <5>  && react-scripts start",

    "start": "run-p watch:css react-scripts:start",
    Looking for react-scripts with an s --^
  },
