如何在Windows上获取waf for Python（用于PyInstaller）

Question

我试图使用PyInstaller构建PYQT4应用程序（取决于win32file模块）。在构建过程中出现此错误。

107 INFO: Bootloader c:\python27\lib\site- 
packages\PyInstaller\bootloader\Window 
s-32bit\runw.exe 
108 INFO: checking EXE 
108 INFO: Building EXE because out00-EXE.toc is non existent 
108 INFO: Building EXE from out00-EXE.toc 

Fatal error: PyInstaller does not include a pre-compiled bootloader for your 
platform. See <http://pythonhosted.org/PyInstaller/#building-the-bootloader> 
for more details and instructions how to build the bootloader. 

要构建的bootloader像here，我需要运行一个WAF命令。那么，我如何获得waf？

Answer 1

通过卸载PyInstaller并使用pip重新安装它来解决此问题。
