chrome.extension.onMessage.addListener阻止chrome.runtime.onInstalled.addListener

Question

添加onMessage-listener会阻止我的onInstalled-listener触发。为什么呢？

这是我的代码：

---

的manifest.json

{
  "name": "BUGTESTER",
  "description": "Hmmmmm...",
  "version": "0.1",

  "background": {
    "persistent": false,
    "scripts": ["background.js"]
  },

  "manifest_version": 2
}

---

background.js

chrome.runtime.onInstalled.addListener(function() {
  alert("onInstalled");
});

//Adding this line breaks the onInstalled-thingy
chrome.extension.onMessage.addListener(function(msg, sender, sendResponse) {});

没问题，只是一个错字，错过了a）和a ;. 加载扩展时是不是有任何语法检查？ = S
