我正在尝试将并行 shell 与Windows上的节点项目一起使用，以同时运行两个进程。
这是我的package.json文件的脚本部分:
"scripts": {
"start": "npm run watch:all",
"test": "echo \"Error: no test specified\" && exit 1",
"lite": "lite-server",
"scss": "node-sass -o css/ css/",
"watch:scss": "onchange \"css/*.scss\" -- npm run scss",
"watch:all": "parallelshell \"npm run watch:scss\" \"npm run lite\""
}
当我运行
npm start命令时，出现以下错误日志:TypeError [ERR_INVALID_ARG_TYPE]: The "options.cwd" property must be of type string. Received type function

我的语法有问题吗？我可以分别运行命令
npm run watch:scss和npm run lite，它们可以正常工作，但是我无法运行parallelshell命令。谢谢!
最佳答案
尝试将并行Shell版本从3.0.2降级到3.0.1
根据声明，这只是一个临时解决方案。
https://github.com/darkguy2008/parallelshell/issues/57
以下是降级 parallelshell 的命令行语法:
sudo npm uninstall --save-dev [email protected]
sudo npm install --save-dev [email protected]
它为我工作。
希望这会有所帮助，并让我们知道。
