Google:Error in event handler for runtime.onInstalled: TypeError: Cannot read property 'sync'...

开发谷歌插件出现错误

错误信息：

Error in event handler for runtime.onInstalled: TypeError: Cannot read property 'sync' of undefined

错误原因

根据官网文档在引入后出错

• manifest.json

{
     
  "name": "Getting Started Example",
  "version": "1.0",
  "description": "Build an Extension!",
  "background" : {
      "scripts" : [ "background.js"],"persistent" : false },
  "manifest_version": 2
}

• background.js

'use strict';

chrome.runtime.onInstalled.addListener(function() {
     
  chrome.storage.sync.set({
     color: '#3aa757'}, function() {
     
    console.log("The color is green.");
  });
});

解决办法

接着看文档后面说明了需要在 manifest.json 文件中加入权限注册

Most APIs, including the storage API, must be registered under the “permissions” field in the manifest for the extension to use them.

更改 manifest.json 文件如下解决问题

{
     
  "name": "Getting Started Example",
  "version": "1.0",
  "permissions": ["storage"],
  "description": "Build an Extension!",
  "background" : {
      "scripts" : [ "background.js"],"persistent" : false },
  "manifest_version": 2
}
