node.js - 如何修复'npm ERR！退出状态 64 ' npm 中的错误

问题描述

我正在设置本地服务器，并且正在运行我的服务器，npm run json:server但出现以下错误：

npm 错误！在 jsonserver@1.0.0 json:server 脚本“json-server --watch db.json”处失败。

不知道如何解决这个问题？

我试图更新npm update -g它并没有帮助。还尝试使用 没有帮助npm i -g npm 在本地安装 json 服务器npm i --save-dev json-server

}

预计在 localhost:3000 上启动服务器

谢谢你的帮助！

解决方案

我认为问题在于您正在将 npm run 脚本的想法与启动json-server合并，并且还没有完全实现这两个方面。以下是我会尝试的步骤，假设您希望有一个运行脚本来启动您的 json-server：

  1. 重命名db.json为，package.json因为这实际上是您package.json的节点项目的文件。您可能在运行时创建了此文件npm init。当您使用自定义脚本命令启动服务器时，此文件不是您为 json-server 模拟的 json 数据。
  2. 创建一个名为db.json的新文件，并为其提供您希望用于 json-server 的模拟 json。例如，从文档中：

db.json：

 {
      "posts": [
        { "id": 1, "title": "json-server", "author": "typicode" }
      ],
      "comments": [
        { "id": 1, "body": "some comment", "postId": 1 }
      ],
      "profile": { "name": "typicode" }
    }

  1. 现在将您的自定义运行脚本命令更改为不包含特殊字符。例如，在您的package.json中更改以下内容：

    "scripts": { "json:server": "json-server --watch db.json" },

至：

"scripts": {
    "start": "json-server --watch db.json"
  },

  1. 现在使用您的自定义脚本命令启动您的服务器：npm run start。此时启动服务器应该没有任何错误。

  2. 现在如果你去http://localhost:3000/posts/1，你应该得到以下 json 响应：

{ "id": 1, "title": "json-server", "author": "typicode" }
