PythonPDF: FileNotFoundError: [WinError 2] The system cannot find the file specified

Question

当我使用 PDFJinja 的示例在现有 PDF 文件中填写表单字段时，我得到以下错误跟踪。

代码段：

        dir_name = os.path.dirname("P:\Project\pdfjinja_services\resources\sample.pdf")
        template_pdf_file = os.path.join(dir_name, 'sample.pdf')
        template_pdf = PdfJinja(template_pdf_file, current_app.jinja_env)
        print(type(template_pdf))
        rendered_pdf = template_pdf({
            'firstName': 'Faye',
            'lastName': 'Valentine'   
        })
        output_file = os.path.join(dir_name, 'output.pdf')
        rendered_pdf.write(open(output_file, 'wb'))

错误：

我正在使用 python-3.9.6 和 PDFJinja-1.1.0。如果我缺少任何其他依赖项，请告诉我。

您缺少一个二进制文件（每个更新 pdftk），或者该二进制文件不在您的搜索路径中。
