如何在win32上调试文件系统“访问被拒绝”错误？

Question

我在与我们的构建脚本时地狱现在：我使用Waf以推动我们的构建过程，一切都进展顺利，但在Windows上，我在哪里期间建立越来越阵性错误。

的错误总是基本上都是“拒绝访问”的这种或那种形式的错误，与我已经在构建过程中创造，使一些工具来运行和做的工作临时文件。例如，运行NSIS生成可执行安装程序之前，我不得不“舞台”所有必需的文件到构建目录，并从那里运行命令。有时候，工作的事情如预期，但其他时候，我得到一个错误报道了我抄例如文件之一：

File: failed opening file "Platform\\Win32\\lxml-2.2.1-py2.6-win32.egg

我花了年龄试图找出什么问题，但其真的很难，因为问题是间歇性的。我想的最后一件事是用procmon监控文件系统访问，试图追查是什么导致了访问错误：我知道这个文件是存在的，因此必须是什么打开了该文件。我在下面包括了相关的输出，因为我看不出什么是错误的：Python似乎在NSIS想要打开它之前关闭文件，但是NSIS失败。任何人都可以对此有所了解吗？这个问题不是孤立的这种情况也给我在那里产卵子进程与我抄建立目录中的文件工作其他情况下...
