Google API：在调用get_credentials（）时表单KeyError：'_ module'

Question

我在快速入门页面suggest上有与谷歌相似的代码。

except ImportError:
    flags = None

    home_dir = os.path.expanduser('~')
    credential_dir = os.path.join(home_dir, '.credentials')
    if not os.path.exists(credential_dir):

        spreadsheetId=spreadsheetId, range=rangeName).execute()

            print('%s, %s' % (row[0], row[4]))


if __name__ == '__main__':
    main()

首先，我创建了自己的秘密文件。然后执行没有该文件'sheets.googleapis.com-python-quickstart.json'和.credentials文件夹创建，但面临sheets.googleapis.com-python-quickstart.json: No such file or directory错误

那么我在该文件夹上创建了空文件sheets.googleapis.com-python-quickstart.json，但面临另一个错误KeyError: '_module'。我甚至试图将我的秘密文件重命名为sheets.googleapis.com-python-quickstart.json - 同样的错误。我已从控制台和ipython笔记本执行此代码 - 同样的错误。通过删除.readonly来改变SCOPES - 没有帮助

是否应该打开任何网页？我究竟做错了什么？

我的问题看起来与as相同 - 但没有任何帮助，我的问题应该是有点不同的想法
