值错误:无效 \x 转义: [英] ValueError: invalid \x escape:

问题描述

ValueError: invalid \x escape:
  File "SConstruct", line 49:
    execfile("hosts.cfg")

我完全被这个家伙难住了......

I'm completely stumped with this one guys...

如果我在第 49 行之前打印，我可以看到输出.在hosts.cfg"的第一行，我放置了第二个从未执行过的打印语句.

If I print right before line 49, I can see the output. On the very first line of "hosts.cfg" I put a second print statement which is never executed.

推荐答案

即使在 Windows 上，正斜杠也适用于目录名称，因此您可以对这些名称进行标准化:

Even on Windows, forward slashes should work for directory names, so you could standardize on those:

"libpath" : [".", "../xlib", "../tools", "../info"],

或者使用原始字符串，正如@Adam Rosenfield 在评论中已经说过的:

Or use raw strings, as @Adam Rosenfield already said in a comment:

"libpath" : [r".", r"..\xlib", r"..\tools", r"..\info"],

我认为上述两种解决方案都比将所有反斜杠加倍更好，并且加载比仅对以x"开头的目录名称加倍反斜杠更好.

I think both of the above solutions are better than doubling all the backslashes, and loads better than just doubling backslashes for directory names that start with 'x'.
