  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"

    "core-js": "^3.6.5",
    "lodash": "^4.17.19"
  },
  "devDependencies": {},

}

我是 npm 的新手，所以我不知道如何修复这个错误 我已经尽力了，如果你能帮助我，我会很高兴

Answer 1

您正在使用 NPM's global flag 安装 Parcel：-g 全局安装，因此您可以从任何地方访问该包。

要安装到本地目录或项目，只需删除标志：

npm install parcel-bundler

安装包时，它的依赖项也会自动安装，因此您无需手动添加它们。
