.vdisplay.start()中的错误 - xvfbwrapper无法正常工作

Question

安装xvfbwrapper python module.provided在MAC中的python selenium测试中启动显示

from xvfbwrapper import Xvfb

class San(unittest.TestCase):
    def setUp(self):
        #display = Display(visible=0, size=(1480, 2000))
        #display.start()
        self.vdisplay = Xvfb(width=1480, height=2000)
        self.vdisplay.start()
        self.driver = webdriver.Chrome()

运行测试用例时,会发生错误

Traceback (most recent call last):
  File "san98.py", line 34, in setUp
    self.vdisplay.start()
  File "/Library/Python/2.7/site-packages/xvfbwrapper.py", line 53, in start
    stderr=open(os.devnull),
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 1308, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory
