我在我的节点项目中使用并发npm 包(5.1.0)来并行运行两个 npm 脚本。但是当我npm start在 cmd 提示符下运行以启动我的脚本时,同时尝试在我认为是我的主目录(我的机器上的 system32 文件夹)中运行命令。

我的 package.json 中有以下内容:

{
  "scripts": {
    "build:watch": "tsc -p src/ -w",
    "serve": "lite-server -c=bs-config.json",
    "start": "concurrently \"npm run build:watch\" \"npm run serve\""
  }
}

这是我得到的输出:

> concurrently "npm run build:watch" "npm run serve"

我尝试了不同版本的并发,并试图找到一种动态指定工作目录的方法,但失败了。任何帮助将不胜感激。

我通过切换到npm-run-all解决了我的问题。

安装后,我只是将命令更改为以下内容:

"start": "run-p build:watch serve"
