imaplib.py："NoneType"对象没有属性"替换"

Question

我已经在GitHub上设置了一个工作流，当我运行它时，我得到以下错误:

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):
9    File "/home/runner/work/Bot-Deschamps-Newsletter/Bot-Deschamps-Newsletter/app.py", line 9, in <module>
10      main()
11    File "/home/runner/work/Bot-Deschamps-Newsletter/Bot-Deschamps-Newsletter/app.py", line 5, in main
12      mail_connect()
13    File "/home/runner/work/Bot-Deschamps-Newsletter/Bot-Deschamps-Newsletter/read_email.py", line 13, in mail_connect
14      mailbox = MailBox(SMTP_SERVER).login(
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.

这个imaplib.py文件不在我的项目中，但我正在导入imap-tools依赖项，我不知道它是否可能是原因。有没有可能跟这个有关?唯一的解决方案是寻找其他依赖项或有其他选择吗?

下面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的工作流执行动作:

#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: Install Python dependencies
uses: py-actions/py-dependency-install@v2
with:

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

requirements.txt:

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

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('rnrn')
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)

问题是您的电子邮件和密码的环境变量没有在GitHub工作流环境中设置。按如下方式修改工作流的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

根据您在GitHub中创建秘密时的命名方式进行修改。
