这是我的代码:

我一直读到我需要编辑凭证文件，但我似乎找不到它.我安装了Windows 7.有谁知道我需要做什么才能克服这个错误?我在这方面完全是个菜鸟，所以如果我对此有点笨手笨脚，请原谅我.谢谢！

I keep reading that I need to edit a credentials file, but I can't seem to find it. I have windows 7 installed. Does anyone know what I need to do in order to get past this error? I'm a total noob at this so please excuse me if I seem a bit nooby about this. Thanks!
