python - wkhtmltopdf 错误 "No such file or directory"(Django)

Question

我正在尝试使用 wkhtmltopdf 从 HTML 代码创建 PDF。我使用过 xhtml2pdf 和 pisa，但我在使用 css 样式时遇到了问题。好吧，wkhtmltopdf 是我最后的选择。

我已经按照这些步骤操作了。 https://github.com/incuna/django-wkhtmltopdf

sudo aptitude install libfontconfig
pip install django-wkhtmltopdf

如果我将“wkhtmltopdf”添加到我的 INSTALLED_APPS，它将识别 wkhtmltopdf 路径。

INSTALLED_APPS = ["wkhtmltopdf"]

好吧，当我尝试生成 PDF 时生成错误。

这是我的代码:

from wkhtmltopdf.views import PDFTemplateResponse 

 context = {
            'linkedin1':self.linkedin1,
            'twitter1':self.twitter1,
            'facebook1':self.facebook1,
            'current': get_current_base_url,
           }


    html_path = "app/folder/page1_1.html"
    response = PDFTemplateResponse(request=request,
                                   template=html_path,
                                   filename="hello.pdf",
                                   context= context,
                                   show_content_in_browser=False,
                                   cmd_options=settings.WKHTMLTOPDF_CMD_OPTIONS,
                                   )

在设置中:

WKHTMLTOPDF_CMD_OPTIONS = {
'quiet': True,
}

我的错误:

 File "/home/user/.virtualenvs/app/local/lib/python2.7/site-   packages/django/core/handlers/base.py", line 136, in get_response
response = response.render()
 File "/home/user/.virtualenvs/app/local/lib/python2.7/site-packages/django/template/response.py", line 104, in render
self._set_content(self.rendered_content)
File "/home/user/.virtualenvs/app/local/lib/python2.7/site- packages/wkhtmltopdf/views.py", line 144, in rendered_content
footer_filename=footer_filename)
File "/home/user/.virtualenvs/app/local/lib/python2.7/site-packages/wkhtmltopdf/views.py", line 103, in convert_to_pdf
return wkhtmltopdf(pages=[filename], **cmd_options)
File "/home/user/.virtualenvs/app/local/lib/python2.7/site-packages/wkhtmltopdf/utils.py", line 92, in wkhtmltopdf
return check_output(ck_args, **ck_kwargs)
File "/usr/lib/python2.7/subprocess.py", line 537, in check_output
process = Popen(stdout=PIPE, *popenargs, **kwargs)
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

我认为它找不到“wkhtmltopdf”。

我的 wkhtmltopdf 安装路径是:

/home/user/.virtualenvs/app/local/lib/python2.7/site-packages/wkhtmltopdf/

好吧，我在设置中添加:

WKHTMLTOPDF_CMD = '/home/user/.virtualenvs/app/local/lib/python2.7/site-packages/wkhtmltopdf/'

查找 wkhtmltopdf 和应用程序“路径权限被拒绝”

有什么问题？，缺少什么？，有什么问题？。

我正在使用: Ububtu 服务器 12.04/64 位， Django 1.4， 皮洪 2.7，

感谢您的回答。

我按照本教程解决了 mi 问题

http://www.cristalab.com/tutoriales/crear-pdf-en-django-y-virtualenv-c110664l/

apt-get build-dep libqt4-gui libqt4-network libqt4-webkit
apt-get install openssl build-essential xorg git-core git-doc libssl-dev wkhtmltopdf 

在设置中

WKHTMLTOPDF_CMD = "/usr/bin/wkhtmltopdf"

但是出现了新的错误:

File "/home/user/.virtualenvs/app/local/lib/python2.7/site- packages/django/template/response.py", line 104, in render
self._set_content(self.rendered_content)
File "/home/user/.virtualenvs/app/local/lib/python2.7/site-  packages/wkhtmltopdf/views.py", line 144, in rendered_content
footer_filename=footer_filename)
File "/home/user/.virtualenvs/app/local/lib/python2.7/site-packages/wkhtmltopdf/views.py", line 103, in convert_to_pdf

CalledProcessError: Command '['/usr/bin/wkhtmltopdf', '--encoding', u'utf8', '--quiet', '/tmp/wkhtmltopdfE_THjv.html', '-']' returned non-zero exit status 

已解决:

------------ 7 月 14 日 ----------

0) 创建一个 ~/tmp/目录并切换到里面

cd ~
mkdir tmp
cd tmp

1) libwkhtmltox-0.11.0_rc1-amd64.tar.bz2 和 wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2 来自 http://code.google.com/p/wkhtmltopdf/downloads/list

 wget https://wkhtmltopdf.googlecode.com/files/libwkhtmltox-0.11.0_rc1-amd64.tar.bz2

 wget https://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2

2) 创建子文件夹并将文件移动到其中:

 mkdir libwkhtmltox
 mkdir wkhtmltopdf

 mv libwkhtmltox-0.11.0_rc1-amd64.tar.bz2 libwkhtmltox
 mv wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2 wkhtmltopdf

3) 进入先前创建的文件夹并解压缩文件。

 cd libwkhtmltox
 tar -xvjf libwkhtmltox-0.11.0_rc1-amd64.tar.bz2 
 cd ../wkhtmltopdf
 tar -xvjf wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2 

4) 访问“lib”。在那里我们找到一个名为“libwkhtmltox.so”的文件，然后将其移动

cd ../libwkhtmltox/lib/
sudo cp libwkhtmltox.so /usr/local/lib/

5) 进入include，找到一个名为'wkhtmltox'的文件夹，然后移动它

cd ../include/
sudo cp -avr wkhtmltox/ /usr/local/include/

6) 解压缩文件后，我们找到文件“wkhtmltopdf-amd64”，将其移动。

cd ../../wkhtmltopdf/
sudo cp wkhtmltopdf-amd64 /usr/bin/

7) 我正在关注这篇文章。 http://www.cristalab.com/tutoriales/crear-pdf-en-django-y-virtualenv-c110664l/

8) 安装

sudo aptitude install libfontconfig

sudo apt-get build-dep libqt4-gui libqt4-network libqt4-webkit 

sudo apt-get install openssl build-essential xorg git-core git-doc libssl-dev wkhtmltopdf

9) 我正在关注这篇文章，https://github.com/incuna/django-wkhtmltopdf

10) 稍后安装应用程序

 pip install django-wkhtmltopdf

还有另一种解决方案:在您的 pip 安装之上，只需从此处安装相关版本的 wkhtmltopdf 二进制文件:http://wkhtmltopdf.org/downloads.html .就我而言，这解决了问题。
