我已经搜索了这个错误的含义，但我无法理解解决方案。有人可以快速帮助我吗？请让您的答案简单易懂。

Answer 1

通过 Google，问题似乎可能是指定的路径不正确。如果您指定这样的路径:

C:\Documents and Settings\jdoe

如果后面的字符是“u”，则 \ 字符可以被解释为错误的 unicode 字符。解决方案是以下之一:

1. 将 \ 替换为另一个 \ - 例如:

   C:\\Documents and Settings\\jdoe

2. 使用 / 代替(这可能是更好的解决方案，因为它适用于所有平台 - 不仅仅是 Windows - 例如:

   C:/Documents and Settings/jdoe
