python中imgkit和wkhtmltoimage 与xvfb的坑

Question

刚刚想做一个图片,发现这个问题

import imgkit
html = imgkit.from_url(url="https://www.baidu.com",output_path="out.png")

运行后发现报这个错

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "D:/EJU/dealspiders/qiyewecat/demo3.py", line 7, in <module>
    html = imgkit.from_url(url="https://www.baidu.com",output_path="out.png")
  File "C:\Users\EJU\AppData\Local\Programs\Python\Python36\lib\site-packages\imgkit\api.py", line 31, in from_url
    cover_first=cover_first)
  File "C:\Users\EJU\AppData\Local\Programs\Python\Python36\lib\site-packages\imgkit\imgkit.py", line 34, in __init__
    self.config = Config() if not config else config
  File "C:\Users\EJU\AppData\Local\Programs\Python\Python36\lib\site-packages\imgkit\config.py", line 36, in __init__
    'http://wkhtmltopdf.org\n'.format(self.wkhtmltoimage))
OSError: No wkhtmltoimage executable found: "b''"
If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - http://wkhtmltopdf.org

一番找解决方式后,把代码改成了

import imgkit
path_wk = r"E:\\software\\wkhtmltopdf\\bin\\wkhtmltoimage.exe"
config = imgkit.config(wkhtmltoimage=path_wk)
html = imgkit.from_url(url="https://www.baidu.com",config=config,output_path="out.png")

然后wkhtmltoimage不报错了,但是xvfb却依然过不去

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "D:/EJU/dealspiders/qiyewecat/demo2.py", line 14, in <module>
    config = imgkit.config(wkhtmltoimage=path_wk)
  File "C:\Users\EJU\AppData\Local\Programs\Python\Python36\lib\site-packages\imgkit\api.py", line 101, in config
    return Config(**kwargs)
  File "C:\Users\EJU\AppData\Local\Programs\Python\Python36\lib\site-packages\imgkit\config.py", line 44, in __init__
    'read it. Otherwise please install xvfb -'.format(self.xvfb))
OSError: No xvfb executable found: "b''"
If this file exists please check that this process can read it. Otherwise please install xvfb -

求大神指点

path_wk = r"E:\\software\\wkhtmltopdf\\bin\\wkhtmltopdf.exe"
config = imgkit.config(wkhtmltopdf=path_wk)
html = imgkit.from_url(url="https://www.baidu.com", config=config, output_path="out.png")
