执行imgkit时出现意外错误

Question

我是Python的新手，在学习imgkit (PI模块)时，我遇到了这个错误，这对于一个简单的代码来说是意想不到的。下面是代码

import imgkit

imgkit.from_url('https://www.google.co.in/','fs.jpg')

我得到的错误是

Traceback (most recent call last):
  File "G:\python\lib\site-packages\imgkit-0.1.8-py3.6.egg\imgkit\config.py", line 30, in __init__
    with open(self.wkhtmltoimage):
FileNotFoundError: [Errno 2] No such file or directory: b''

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\ALEXANDER\Desktop\def img.py", line 3, in <module>
    imgkit.from_url('https://www.google.co.in/','fs.jpg')
  File "G:\python\lib\site-packages\imgkit-0.1.8-py3.6.egg\imgkit\api.py", line 20, in from_url
    rtn = IMGKit(url, 'url', options=options, toc=toc, cover=cover, config=config, cover_first=cover_first)
  File "G:\python\lib\site-packages\imgkit-0.1.8-py3.6.egg\imgkit\imgkit.py", line 34, in __init__
    self.config = Config() if not config else config
  File "G:\python\lib\site-packages\imgkit-0.1.8-py3.6.egg\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

谁能告诉我我做错了什么？

Answer 1

在windows系统上安装wkhtmltopdf后，您需要执行以下操作：

path_wkthmltoimage = r'C:\Program Files\wkhtmltopdf\bin\wkhtmltoimage.exe'
config = imgkit.config(wkhtmltoimage=path_wkthmltoimage)

imgkit.from_file('table.html', 'table.jpg',config=config)

Answer 2

尝试：brew install caskroom/cask/wkhtmltopdf

Answer 3

看起来你需要安装wkhtmltopdf。为此，请运行pip install wkhtmltopdf
