無法識別的清單鍵 'externally_connectable'

Question

我得到擴展頁面上此錯誤：

Unrecognized manifest key 'externally_connectable'. 

這是我的清單：

{ 
    "manifest_version": 2, 

    "name": "Publish", 
    "externally_connectable": { 
     "ids": ["*"], 
     "matches": ["*://*.example.it/*"] 
    }, 
    "description": "example ext", 
    "version": "2.0", 
    "browser_action": { 
    "default_icon": "favicon.ico", 
    "default_popup": "popup.html" 
    }, 
    "background": { 
    "page": "background.html" 
    }, 

    "permissions": [ 
    "http://www.example.it/", "tabs", "http://localhost/", "http://www.example.it/", "https://*/*", "http://*/*", "notifications", "background" 
    ], 
    "web_accessible_resources": [ 
    "img/example.png", 
    "img/bg_site.gif" 
    ] 
} 

如何解決這個問題呢？我serched比格上，沒有一個人寫了一篇關於這個錯誤...

你運行的是Chrome 26.0.1410.63，但在版本加入這個清單鍵29

• History of the Chromium source code dealing with this manifest key
• Bug for which this manifest key was added

Answer 2

如果你有這樣的錯誤與Chrome瀏覽器的新版本可能犯過我犯同樣的錯誤 - 我有一個空間在密鑰名稱的末尾（在引號內）。
