Question

我有一个角度项目，我试图在该项目中创建自定义脚本，这是我第一次使用脚本。我在执行脚本时遇到麻烦。我收到以下错误：

到目前为止，我仅测试了一个简单的脚本，即：

console.log("Hello World");

因此，我猜测错误与脚本位置有关。目前，我已将其保存在与package.json文件相同的位置。 这是正确的位置吗？我是否引用错误（见下文）？如果不是，我打算在哪里存储自定义脚本？预先感谢。

这是我的package.json文件：

"scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "patch": "ngsw-patch.js"
  }

就像我在评论中解释的那样，最佳实践是将您的脚本放在“ scripts”文件夹下。

脚本无法运行的原因是因为您需要执行js。

NodeJS是可以实现此目的的工具。

所以您的脚本部分看起来像

"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "ng build",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e",
"patch": "node ngsw-patch.js"

}

比简单地打电话

npm run patch

或使用非常出色的工具“纱线”

NPM脚本-在哪里保存本地项目的自定义脚本？
