如何在IIS 7.5上使用django-wkhtmltopdf生成pdf文件 - 8

我使用django-wkhtmltopdf在我的webapp中生成pdf，使用django集成服務器工作正常，但是當我使用IIS 7.5或8時，出現此錯誤： WindowsError [錯誤6句柄無效如何在IIS 7.5上使用django-wkhtmltopdf生成pdf文件 - 8

IIS可能在不同的用戶下運行？這也是：http://stackoverflow.com/questions/3028786/how-cani-i-fix-error-6-the-handle-is-invalid-with-pyserial –

終於得到了它，thank's to n1b0r。我必須更新python27/lib中CHECK_OUT方法/ subprocess.py這樣

來自：

if 'stdout' in kwargs: 
    raise ValueError('stdout argument not allowed, it will be overridden.') 
process = Popen(stdout=PIPE, *popenargs, **kwargs)

到：

if 'stdout' in kwargs: 
     raise ValueError('stdout argument not allowed, it will be overridden.') 
kwargs.pop('stderr', None) 
process = Popen(stdout=PIPE, stderr=PIPE, stdin=PIPE, *popenargs, **kwargs)

，使其工作在IIS，但如果給出一個錯誤使用django集成服務器。
