此消息一直出现在 chrome 开发者工具的控制台中：

is this a bug in chrome or there is something wrong in my chrome installation?
这是 chrome 中的错误还是我的 chrome 安装有问题？

Based on some googling, this is a problem with a chrome extension, but it may not be clear which. (For me, it was Feedly).
基于一些谷歌搜索，这是 chrome 扩展的问题，但可能不清楚是哪个。（对我来说，它是 Feedly）。
The quickest way to find out which is causing the problem:
找出问题原因的最快方法：
- Disable all your chrome extensions. (Chrome menu > tools > extensions)
- Refresh a page - hopefully the port error should be gone now
- Re-enable your extensions one by one, refreshing the page after each, 'til the error pops up again in the console. You should now have your culprit.
- 禁用所有 chrome 扩展程序。（Chrome 菜单 > 工具 > 扩展）
- 刷新页面 - 希望端口错误现在应该消失
- 一个一个地重新启用你的扩展，在每个扩展之后刷新页面，直到错误再次在控制台中弹出。你现在应该知道你的罪魁祸首了。
I know this could be a pain if there are a lot of extensions :/ personally, I took it as a chance to prune the unused / unworthy extensions while I was going through them.
我知道如果有很多扩展，这可能会很痛苦：/就我个人而言，我把它当作一个机会，在我浏览它们时修剪未使用的/不值得的扩展。

It seems to be a problem with the Google Dictionary (by Google)
This scriptdoesn't seem to exist or is not accessible by that port.
该脚本似乎不存在或无法通过该端口访问。
