Windows中的Python XVFB错误

对于虚拟Framebuffer(无头测试),我正在使用Xvfb和PyVirtualDisplay,它在Ubuntu中工作正常,但在Windows7中显示错误.这是问题发生的代码的一部分.

from pyvirtualdisplay import Display
display = Display(visible=1, size=(300, 400))
display.start() 

但是当我在Windows中运行相同的命令时,我收到此错误

Traceback (most recent call last):
  File "C:\Python27\Scripts\pynt-script.py", line 9, in <module>
    load_entry_point('pynt==0.8.0', 'console_scripts', 'pynt')()

    raise EasyProcessCheckInstalledError(self)
easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=[Error 2] The system cannot find the file specified
Program install error! 

我想我的程序无法找到xvfb程序/库？
我安装了xvfbwrapper(https://github.com/cgoldberg/xvfbwrapper),但问题仍然存在.我认为xvfbwrapper与xvfb有什么不同？

适用于Windows平台的任何替代方案,可以进行无头测试(虚拟帧缓冲)

解决方法:

您收到错误,因为找不到命令Xvfb. Xvfb是X虚拟帧缓冲区,它不是Microsoft Windows 7的一部分.
