Python 脚本运行直接通过命令行而不是运行通过 shell/bash 脚本

Question

我有一个 python 脚本 main.py 它做了一些事情并且每天通过 crontab 运行它我创建了以下文件（我认为它叫做 bash 脚本):

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

一段时间以来，它每天运行都没有任何问题。

现在我添加了一项功能，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 google 驱动器。当通过命令行运行连接这个新脚本时，它运行每次都成功且没有任何错误。

我假设 crontab 也会运行，但现在我得到下面的 Traceback。

/Users/PathToProject/venv/lib/python3.8/site-packages/oauth2client/_helpers.py:255: UserWarning: Cannot access mycreds.json: No such file or directory

    raise InvalidConfigError("Invalid client secrets file %s" % error)
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 up/downloading 到 google 驱动器的部分，它工作正常。

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。该错误消息似乎具有误导性，因为 client_secrets.json 在目录中并且它通过命令行工作。

当您运行通过命令行选择 json 文件的路径并且 others.Cron 在路径中找不到 path.Be 绝对路径时，它将运行顺利。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。
