from TwitterFollowBot import TwitterBot
my_bot = TwitterBot()

from TwitterFollowBot import TwitterBot
my_bot = TwitterBot("config.txt")  

from TwitterFollowBot import TwitterBot   
my_bot = TwitterBot()
my_bot.sync_follows()

from TwitterFollowBot import TwitterBot    
my_bot = TwitterBot()
my_bot.auto_rt("@ShoutGamers", count=2200)

Crontab不会在其所在的目录中运行您的代码，因为它只运行您从其配置的任何位置（可能是您的主目录）放入的命令。

您可以通过sys.argv获取文件的路径来解决此问题：

#!/usr/bin/env python

import sys
import os.path
from TwitterFollowBot import TwitterBot

path = sys.argv[0].rsplit("/", 1)[0]

TwitterBot()  # I don't know if this does something, but as the assigned value is never used...

TwitterBot(os.path.join(path, "config.txt"))  # Same here. I put the path in front of "config.txt"

TwitterBot().sync_follows()

TwitterBot().auto_rt("@ShoutGamers", count=2200)

Crontab问题，即使我在目录中有文件也说＆＃34;没有这样的文件或目录＆＃34;
