我现在在构建脚本上玩得很开心:我正在使用 Waf来插入我们的构建过程，一切都很好，除了在 Windows 上，我在构建过程中遇到间歇性错误。
错误基本上总是一种或另一种形式的“访问被拒绝”错误，与我在构建过程中创建的临时文件有关，以使某些工具能够运行并完成它的工作。例如，在运行 NSIS 之前要生成可执行安装程序，我必须将所有必需的文件“暂存”到构建目录并从那里运行命令。有时事情会按预期工作，但有时我会收到有关我复制的其中一个文件的错误报告，例如:
文件:打开文件“Platform\\Win32\\lxml-2.2.1-py2.6-win32.egg”失败
我花了很长时间试图找出问题所在，但这真的很难，因为问题是间歇性的。我尝试的最后一件事是使用 procmon监视文件系统访问以尝试跟踪导致访问错误的原因:我知道该文件在那里，所以一定是某些东西打开了该文件。我在下面包含了相关的输出，因为我看不出有什么问题:Python 似乎在 NSIS 想要打开它之前关闭了文件，但随后 NSIS 失败了。任何人都可以阐明这一点吗？这个问题不仅与这种情况有关，而且与我生成子进程以处理我已复制到构建目录的文件的其他情况有关...

最佳答案
在该跟踪中，文件在跟踪开始时已经存在。所以其他东西可能使它保持打开状态(例如病毒扫描程序或索引服务)。
