dlopen（）无法加载库：cairo / cairo-2 [英] dlopen() failed to load a library: cairo / cairo-2

问题描述

这是我的观点：

from django.conf import settings
from django.http import HttpResponse
from django.template.loader import render_to_string
import weasyprint



    @staff_member_required
    def admin_order_pdf(request, order_id):
        order = get_object_or_404(Order, id=order_id)
        html = render_to_string('orders/order/pdf.html', {'order': order})
        response = HttpResponse(content_type='application/pdf')
        response['Content-Disposition'] = 'filename="order_{}.pdf"'.format(order.id)
        weasyprint.HTML(string=html).write_pdf(response,
                                               stylesheets=[weasyprint.CSS(settings.STATIC_ROOT + 'css/pdf.css')])
        return response

当我想导入（导入weasyprint）它给我一个错误。

when i want to import (import weasyprint) it gives me a error.

ERROR:

Request Method: GET
Request URL:    http://127.0.0.1:8000/admin/orders/order/
Django Version: 1.8.6
Exception Type: OSError
Exception Value:    
dlopen() failed to load a library: cairo / cairo-2

我已经安装了weasyprint和cairocffi。我正在使用osx EI CAPITAN。

I already installed weasyprint and cairocffi. I'm using osx EI CAPITAN.

推荐答案

这是通过在Ubuntu上安装以下依赖项解决的：

This was solved for me by installing the following dependencies on Ubuntu:

 sudo apt-get install libpango1.0-0
 sudo apt-get install libcairo2
 sudo apt-get install libpq-dev
