Python 如何使用Django输出PDF？

我指的是使用reportlab生成pdf

def some_view(request):
    # Create the HttpResponse object with the appropriate PDF headers.
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'attachment; filename="somefilename.pdf"'

    # Create the PDF object, using the response object as its "file."
    p = canvas.Canvas(response)

    # Draw things on the PDF. Here's where the PDF generation happens.
    # See the ReportLab documentation for the full list of functionality.
    p.drawString(100, 100, "Hello world.")

    # Close the PDF object cleanly, and we're done.
    logging.debug('-----p---')
    logging.debug(p)
    p.showPage()
    p.save()
    return response

如果我在myapp中添加此reportlab文件夹，则会出现以下错误：

ViewDoesNotExist at /aps/print-pdf/
Could not import myapp.views. Error was: No module named reportlab

ViewDoesNotExist at /aps/print-pdf/
Tried some_view in module myapp.views. Error was: 'HardenedModulesHook' object has no attribute '_files'

如果我将此reportlab文件夹从myapp文件夹中取出，则会出现以下错误：

ViewDoesNotExist at /aps/print-pdf/
Could not import myapp.views. Error was: No module named reportlab

ViewDoesNotExist at /aps/print-pdf/
Tried some_view in module myapp.views. Error was: 'HardenedModulesHook' object has no attribute '_files'

这有什么不对？请帮忙

检查

myapp

是否在您的设置中。是否安装了应用程序

检查

reportlab

是否成功安装在python环境中，使用

pip freeze

或运行python shell以查看

import reportlab

是否可以工作

您是如何安装reportlab的？你使用virtualenv吗？
