带有玩笑的 Puppeteer 脚本失败并出现错误：找不到模块 'P:\jest\bin\jest.js'

Question

I am trying to run a simple puppeteer script with jest. Below is my package.json contents:

    {
  "name": "jest-puppeteer-project",
  "version": "1.0.0",
  "description": "Test framework using Jest and Puppeteer",
  "main": "index.js",
  "scripts": {
    "test": "jest --forceExit"
  },
  "author": "Anil Kumar Cheepuru",
  "license": "ISC",
  "dependencies": {
    "@babel/core": "^7.12.3",
    "@babel/preset-env": "^7.12.1",
    "babel-jest": "^26.6.3",
    "jest": "^26.6.3",
    "jest-puppeteer": "^4.4.0",
    "puppeteer": "^5.4.1"
  }
 }

Below is my jest-puppeteer.config.js contents:

module.exports = {
  launch: {
    headless: false,
  },
  browserContext: "default"
};

I have also set preset: "jest-puppeteer" in my jest.config.js file.

Below is the error I am getting in the console when I am trying to run the script using the command: npm run test

I tried to look for a solution in various sources, but no luck. Can anyone please help me with this?

If you installed jest locally into your project, then this command:

"scripts": {
    "test": "jest --forceExit"
}

won't find your locally installed jest. Try changing it to ./node_modules/.bin/jest --forceExit :

"scripts": {
    "test": "./node_modules/.bin/jest --forceExit"
}
