安排cron作业自动电子邮件时出现EOFError

Question

我正在尝试使用crontab每天发送一封电子邮件，但是现在通过尝试每分钟发送一次来进行测试。我正在使用python脚本scheduleCron.py计划cron作业以运行emailTest.py，但是它不起作用。当我分别运行时，它们效果很好！ emailTest.py的目录正确，因为我使用其他非电子邮件代码进行了测试。但是设置cron作业后，我的邮件中出现EOFError，我不知道那是什么意思，因为这是我第一次尝试使用crontab或yagmail。我确实使用了yagmail的建议，即创建一个测试电子邮件帐户并启用第3方访问权限，该操作可以手动运行该脚本，因此不知道为什么现在会出现EOFError。

这是scheduleCron.py

from crontab import CronTab

my_cron = CronTab(user=True)
job = my_cron.new(command='/anaconda3/bin/python3 /Users/bgoldberg/PythonScripts/FunStuff/emailTest.py')
job.minute.every(1)
my_cron.write()

这是emailTest.py

import yagmail
import pandas as pd
from datetime import datetime

# create variables
df = pd.read_excel('/Users/bgoldberg/PythonScripts/FunStuff/holidays.xlsx')
df['DateCheck'] = df['Date'] == datetime.today().strftime('%m/%d')
df = df.loc[df['DateCheck'] == True]
df.reset_index(inplace=True)
if len(df) == 1:
    holiday1 = df.at[0, 'Holiday']
    link1 = df.at[0, 'Link']
    content = f'Happy {holiday1}! {link1}'
elif len(df) > 1:
    holiday1 = df.at[0, 'Holiday']
    link1 = df.at[0, 'Link']
    holiday2 = df.at[1, 'Holiday']
    link2 = df.at[1, 'Link']
    content = f'Happy {holiday1}! {link1} \nHappy {holiday2}! {link2}'
else:
    pass

weekday = datetime.today().strftime('%A')

# create email
receiver = 'blah@gmail.com'
body = f'{content}'

yag = yagmail.SMTP('blah@gmail.com')
yag.send(
        to = receiver,
        subject = 'Fun Daily Holidays',
        contents = body
)

这是我在邮件中收到的错误：
