在我的 package.json 文件中，我有以下脚本：

"scripts": {
    "start": "npm run watch:all",
    "test": "echo \"Error: no test specified\" && exit 1",
    "lite": "lite-server",
    "sass": "node-sass -o sass/ css/",
    "watch:sass": "onchange 'sass/*.scss' -- npm run sass",
    "watch:all": "parallelshell 'npm run watch:sass' 'npm run lite'"
  }

每当我运行我的代码时，我都会收到以下错误消息：

 crs@1.0.0 start /home/hazem/crs
> npm run watch:all


> crs@1.0.0 watch:all /home/hazem/crs
> parallelshell 'npm run watch:sass' 'npm run lite'

child_process.js:422
    throw new ERR_INVALID_ARG_TYPE('options.cwd', 'string', options.cwd);
    ^

那么，在这种情况下，可能是什么问题？脚本有问题吗？还是 nodejs 中的 Parallelshell 脚本中的错误？

Parallelshell 存在问题，必须手动修复；

转到文件：

node_modules/parallelshell/index.js:105

然后更改此行：

cwd: process.versions.node < '8.0.0' ? process.cwd : process.cwd(),

对此：

cwd: parseInt(process.versions.node) < 8 ? process.cwd : process.cwd(),

完成！

密码：

parseInt(process.versions.node) < 8 ? process.cwd : process.cwd()

如果您在执行此操作后仍然遇到问题，则必须使用以下行降级 paralleshell 的版本：

sudo npm install --save-dev parallelshell@3.0.1

它对我有用。

它对我有用，因为我遇到了类似的问题，parallelshell 3.2.2 无法处理我的节点，所以我必须降级它
