python - FileNotFoundError: [Errno 2] 没有这样的文件或目录 (Heroku)

Question

我正在使用 Flask 创建一个 Web 应用程序并使用 Heroku 进行部署，我的应用程序在本地正常工作，但是当我尝试在 Heroku 中运行它时，它显示以下错误：

“FileNotFoundError：[Errno 2] 没有这样的文件或目录：'static\perssonel_data'

试图访问目录的函数是这样的：

from PyPDF2 import PdfFileReader, PdfFileWriter
import re
import os

def create_desprendible(id, name, month):

    # folder path with "desprendibles"
    path_test = 'static\perssonel_data'

    # search for the file for the requested month
    for filename in os.scandir(path_test):
        if filename.is_file():
            if filename.path == 'static\perssonel_data\perssonel_data_' + str(month) +'.pdf':
                file_path = filename.path
                pdf = PdfFileReader(file_path)

    # generates PDF
    for i in range(0, pdf.getNumPages()):
        content = ""
        content += pdf.getPage(i).extractText() + "\n"
        ResSearch = re.search(id, content)
        if ResSearch is not None:
            pages = [int(i)]

    pdfWriter = PdfFileWriter()

    pdf_name = 'DESPRENDIBLE_DE_NOMINA_' + str(name).replace(" ", "_") + '.pdf'

    for page_num in pages:
        pdfWriter.addPage(pdf.getPage(page_num))

    with open(pdf_name, 'wb') as f:
        pdfWriter.write(f)
        f.close()

    return pdf_name

我使用了 $ heroku run bash，一切看起来都不错：

    $ heroku run bash

知道会是什么吗？

PD：我知道“人员”拼写错误
