child_process.execSync 执行 npm 运行脚本找不到 package.json

Question

我正在尝试在 child_process 中执行 cypress 并将一些对象传递给规范以执行。我已经尝试使用 execSync 来运行 npm 运行脚本，并在运行将脚本 npm link 然后 npm install -g 像 cli 应用程序一样使用它。我得到这个错误

npm ERR! syscall open
npm ERR! path /home/mohibulhasan/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/home/mohibulhasan/package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

    ^

}

我尝试使用 path 给出当前文件路径以获取 package.json 但找不到它。然后也尝试使用 npm pack 然后安装它，但这也导致了同样的错误。我错过了什么？

package.json

{
  "name": "erp",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "cypress-run": "cypress run --headed 'cypress/integration/todo.spec.js'"
  },

  "dependencies": {
    "chalk": "^4.0.0",
    "commander": "^8.3.0",

  }
}

app.js

#!/usr/bin/env node

const chalk = require('chalk')
const {Command} = require('commander')
const {execSync} = require('child_process')
const path = require('path')
const packgejson = require('./package.json');

const program = new Command();

const greeting = chalk.green.bold("Hello!");

console.log(greeting);
console.log(packgejson)

program
.option('-p, --project-name <type>', 'insert project name')
.option('-t, --task-name <type>', 'insert task name')
.option('-s, --start-time <type>', 'insert start time')
.option('-e, --end-time <type>', 'insert end time')
.option('-h, --work-hour <type>', 'insert work hour')
.option('-r, --report <type>', 'insert report message')
program.parse(process.argv);

const options = program.opts();

console.log(options.projectName)
console.log(options.taskName)
const reportInfo = JSON.stringify(options);
const currentFolderPath = path.resolve(process.cwd());
console.log(currentFolderPath)

execSync(`cd ${currentFolderPath} && npm run cypress-run -- --env reportInfo='${reportInfo}'`, {stdio: 'inherit'})

改用__dirname：

即

const chalk = require('chalk')
const {Command} = require('commander')
const {execSync} = require('child_process')
const path = require('path')
const packgejson = require('./package.json');

const program = new Command();

const greeting = chalk.green.bold("Hello!");

console.log(greeting);
console.log(packgejson)

program
.option('-p, --project-name <type>', 'insert project name')
.option('-t, --task-name <type>', 'insert task name')
.option('-s, --start-time <type>', 'insert start time')
.option('-e, --end-time <type>', 'insert end time')
.option('-h, --work-hour <type>', 'insert work hour')
.option('-r, --report <type>', 'insert report message')
program.parse(process.argv);

const options = program.opts();

console.log(options.projectName)
console.log(options.taskName)
const reportInfo = JSON.stringify(options);
const currentFolderPath = __dirname;
console.log(currentFolderPath)

execSync(`cd ${currentFolderPath} && npm run cypress-run -- --env reportInfo='${reportInfo}'`, {stdio: 'inherit'})
