为什么通过python pdfkit调用时会出现wkhtmltopdf IO错误？

我正试图将我的

wkhtmltopdf

软件包升级到

0.12.2.1

，但运气不好

• 它在更新之前确实起作用了。我尝试更新的原因是 修复PDF页面之间内容的拆分
• 我正在运行-Ubuntu 64x-Trusty
• 我正在通过python pdfkit使用
• 我从获取最新版本的

  wkhtmltopdf

以下是我迄今为止所做/尝试的内容。有人更新过他们的设置吗？或者任何指针都会非常有用！谢谢

开箱即用，我得到了

配置错误

我硬编码就是为了克服这个问题

# -*- coding: utf-8 -*-
import subprocess
import sys

class Configuration(object):
    def __init__(self, wkhtmltopdf='', meta_tag_prefix='pdfkit-'):
        self.meta_tag_prefix = meta_tag_prefix

        self.wkhtmltopdf = wkhtmltopdf

        if not self.wkhtmltopdf:
            if sys.platform == 'win32':
                self.wkhtmltopdf = subprocess.Popen(                    ['where', 'wkhtmltopdf'], stdout=subprocess.PIPE).communicate()[0].strip()
            else:
                self.wkhtmltopdf = subprocess.Popen( ['which', 'wkhtmltopdf'], stdout=subprocess.PIPE).communicate()[0].strip()

        try:
            #with open(self.wkhtmltopdf) as f:
           with open("/usr/local/bin/wkhtmltopdf") as f:
                pass
        except IOError:
            raise IOError('No wkhtmltopdf executable found: "%s"\n'
                          'If this file exists please check that this process can '
                          'read it. Otherwise please install wkhtmltopdf - '
                          'https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf' % self.wkhtmltopdf)

现在我得到这个错误，不知道如何继续。我尝试向上面的Popen添加

shell=True

，但也没有成功

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/rq/worker.py", line 543, in perform_job
    rv = job.perform()

您必须设置

wkhtmltopdf

库的

配置

（路径）

我创建了一个基本的助手函数，如下所示

import os
import pdfkit

WKHTMLTOPDF_PATH = '/usr/local/bin/wkhtmltopdf'

def generate_pdf(html, static_path,  _path):
    config = pdfkit.configuration(wkhtmltopdf=WKHTMLTOPDF_PATH)
    _status = pdfkit.from_string(
        html,
        os.path.join(static_path, _path),
        configuration=config,
        options={
            'page-size': 'A4',
            'margin-top': '0',
            'margin-right': '0',
            'margin-left': '0',
            'margin-bottom': '0',
            'zoom': '1.2',
            'encoding': "UTF-8",
        })
    return _path if _status else ''

使用：

html = "<h1>Hello World !!!</h1>"
static_path = "/static/"
file_path = "pdfs/out.pdf"
generate_pdf(html, static_path, file_path)

html=“你好，世界！！！”
static_path=“/static/”
file_path=“pdfs/out.pdf”
生成pdf（html、静态路径、文件路径）

另一个解决方案（安装

wkhtmltopdf

）：

请注意，现在关门了。因此，如果您想下载最新的二进制文件，请访问

wget http://download.gna.org/wkhtmltopdf/0.12/0.12.3/wkhtmltox-0.12.3_linux-generic-amd64.tar.xz
tar xvf wkhtmltox-0.12.3_linux-generic-amd64.tar.xz
sudo mv wkhtmltox/bin/wkhtmltopdf /usr/local/bin/wkhtmltopdf
sudo chmod +x /usr/local/bin/wkhtmltopdf
