我试图在PyDrive中使用duply / duplicity。但是我一直收到一条非常神秘的错误消息，告诉我参考PyDrive安装联机帮助页。哪个没有提供解决方案。
这是我运行的duply命令的输出，包括错误。
$ duply mac-mini.gdrive status

我正在运行OS X 10.11.3，已经安装了brew和pip。我已经用pip来安装pydrive。
$ pip install pyDrive

对于参考，我正在运行双重和双重的当前版本。
$ duply -V

更新2016/04/25：
与python2-oauth2client 2.00的不兼容性已经修正为双重性0.7.07.1（参见changelog）。我刚刚在一个Linux机器上测试它，它完全正常。
原帖如下：
首先，检查你的python2-oauth2client版本。截至编写本版本时，2.00似乎与双重性无关。我不得不降级回1.5.2才能让它再次运作。
其次，确保不存在由不同python版本（OSX内置与自制软件包与手动安装与pip等）引起的冲突。独家使用自制软件可能是个好主意。
第三，确保您的pydrive配置完成。以下是关于如何使用“普通”Google用户帐户执行此操作的简要说明：
使用以下内容在某处创建pydrive配置文件（例如/etc/duply/pydrive.conf或~/etc/pydrive.conf）：
client_config_backend: settings
client_config:
client_id: <client-id-string>.apps.googleusercontent.com
client_secret: <client-secret-string>
save_credentials: True
save_credentials_backend: file
save_credentials_file: </path/to/save/authdata.json>
get_refresh_token: True
client_id 和 client_secret 可以在Google Developers Console启用后从Google Drive API的API管理器获取。
将 save_credentials_file 设置为pydrive成功连接后可以缓存身份验证数据的任意位置（例如/etc/duply/pydrive.json或~/etc/pydrive.json）。
通过设置 GOOGLE_DRIVE_SETTINGS shell变量来完成此操作：
$ export GOOGLE_DRIVE_SETTINGS=/etc/duply/pydrive.conf
您可能希望将其添加到~/.bashrc，以便所有shell会话都自动设置它。

......你已经完成了。
如果仍然无效，请检查文件权限：用户是否对上面指定的配置文件运行了双重权限？

与python2-oauth2client版本2.00相同的问题。通过降级到python2-oauth2client 1.5.2来解决。适用于Christian Mund的指示。

Duplicity 0.7.10是Python 2脚本。如您所见：
➜ ~ head $(which duplicity)
#!/usr/bin/env python2
# -*- Mode:Python; indent-tabs-mode:nil; tab-width:4 -*-
#
# duplicity -- Encrypted bandwidth efficient backup

因此请确保运行Python 2而不是Python 3。
