Imaplib.py：&#39；NoneType&#39；对象没有属性&#39；替换&#39；

imaplib.py: #39;NoneType#39; object has no attribute #39;replace#39;(Imaplib.py：#39；NoneType#39；对象没有属性#39；替换#39；)

问题描述

我已经在GitHub上设置了一个工作流，当我运行它时，我收到以下错误：

 1    Run python app.py
 2    python app.py
 3    shell: /usr/bin/bash -e {0}
 4    env:
 5      pythonLocation: /opt/hostedtoolcache/Python/3.9.6/x64
 6      LD_LIBRARY_PATH: /opt/hostedtoolcache/Python/3.9.6/x64/lib
 8  Traceback (most recent call last):

10      main()

15    File "/opt/hostedtoolcache/Python/3.9.6/x64/lib/python3.9/site-packages/imap_tools/mailbox.py", line 46, in login
16      login_result = self.box.login(username, password)
17    File "/opt/hostedtoolcache/Python/3.9.6/x64/lib/python3.9/imaplib.py", line 610, in login
18      typ, dat = self._simple_command('LOGIN', user, self._quote(password))
19    File "/opt/hostedtoolcache/Python/3.9.6/x64/lib/python3.9/imaplib.py", line 1222, in _quote
20      arg = arg.replace('\', '\\')
21  AttributeError: 'NoneType' object has no attribute 'replace'
22  Error: Process completed with exit code 1.

此imaplib.py文件不在我的项目中，但我正在导入imap-tools依赖项，我不知道这是否可能是原因。 有没有可能这和这件事有关？唯一的解决方案是寻找其他依赖项，或者是否有其他选择？

编辑1：

以下是我在工作流中运行的文件：

#app.py
from read_email import mail_connect

def main():
    mail_connect()


if __name__ == '__main__':
    main()

在GitHub操作中执行的工作流中：

#main.yml
name: Python Script Workflow

on:
  - cron: "*/10 11-13 * * 1-5"
  
  workflow_dispatch:
    inputs:
      name:
        required: true
        default: 'Tweet'
  
jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout repository content
        uses: actions/checkout@v2 # Checkout the repository content to github runner.

      - name: Setup Python Version
        uses: actions/setup-python@v2
        with:
          python-version: 3.9.6

      - name: Install Python dependencies
        uses: py-actions/py-dependency-install@v2
        with:
          path: "requirements.txt"

      - name: Execute Python script # Run the app.py
        run: python app.py

这是requirements.txt：

imap-tools==0.49.1
python-dotenv==0.19.0
tweepy==4.0.1

编辑2：

这里是唯一使用imap_toolts的文件：

#read_email.py
from imap_tools import MailBox, MailMessageFlags, A
from os import getenv
from dotenv import load_dotenv
from post_tweet import post_tweet


def mail_connect():
    load_dotenv()
    FROM_EMAIL = getenv('FROM_EMAIL')
    FROM_PWD = getenv('FROM_PWD')
    SMTP_SERVER = "imap.gmail.com"

    mailbox = MailBox(SMTP_SERVER).login(
        FROM_EMAIL, FROM_PWD, initial_folder='INBOX')

    read_email(mailbox)


def read_email(mailbox):
    posts = []
    for msg in mailbox.fetch():
        posts = msg.text.replace('*', '').split('

')
        posts = posts[2:-3]
        mark_as_read(mailbox)
        archive_message(mailbox, msg.uid)
    post_tweet(posts)


def mark_as_read(mailbox):
    flags = (MailMessageFlags.ANSWERED, MailMessageFlags.FLAGGED)
    mailbox.flag(mailbox.fetch(A(seen=False)), flags, True)
    mailbox.flag(mailbox.fetch("SENTON 01-Jan-2021"),
                 MailMessageFlags.SEEN, False)


def archive_message(mailbox, msg_uid):
    move_to = 'Tweeted'
    mailbox.move(msg_uid, move_to)

推荐答案

问题是您的电子邮件和密码的环境变量未在GitHub工作流环境中设置。按如下方式修改您的工作流的YAML：

environment:
  name: production

  - name: Execute Python script # Run the app.py
    env:
      FROM_PWD: ${{secrets.FROM_PWD}}
      FROM_EMAIL: ${{secrets.FROM_EMAIL}}

    run: python app.py

如有必要，请根据您在GitHub中创建机密时的命名方式进行修改。
