Python脚本直接通过命令行运行，但不通过shell/bash脚本运行

Question

我有一个python脚本main.py，它做了一些事情，为了每天通过crontab运行它，我创建了以下文件(我认为它被称为bash脚本(：

#!/bin/sh
source /Users/PathToProject/venv/bin/activate
python /Users/PathToProject/main.py

一段时间以来，它每天都在运行，没有任何问题。

现在，我添加了一个功能，可以在main.py中通过PyDrive2将包含一些结果的.CSV文件保存到我的谷歌驱动器中。当通过命令行运行这个新脚本时，它每次都能成功运行，没有任何错误。

我以为crontab也会运行，但现在我得到了下面的Traceback。

pydrive2.settings.InvalidConfigError: Invalid client secrets file ('Error opening file', 'client_secrets.json', 'No such file or directory', 2)

如果我编辑python脚本并跳过上传/下载到谷歌驱动器的部分，它会很好地工作。

现在我不知道为什么会出现这个错误，也不知道如何解决这个问题。错误消息似乎具有误导性，因为client_secrets.json在目录中，它通过命令行工作。

当您通过命令行运行时，它会为json文件和其他文件选择路径。克朗找不到路。在道路上要绝对，它会顺利运行。如果绝对路径不可能，请尝试相对于CRON位置路径的相对路径。
