python - Pydrive 后端不适用于口是心非——python

Question

我正在尝试对 PyDrive 使用双重/口是心非。但是，我不断收到一条非常神秘的错误消息，告诉我引用 PyDrive 安装联机帮助页。没有提供解决方案。

这是我正在运行的重复命令的输出，包括错误。

$ duply mac-mini.gdrive status

我运行的是 OS X 10.11.3，安装了 brew 和 pip。我使用 pip 安装 pydrive。

$ pip install pyDrive

作为引用，我正在运行 duplicity 和 duply 的当前版本。

$ duply -V
  duply version 1.11.1
  (http://duply.net)

  Using installed duplicity version 0.7.06, python 2.7.10, gpg 1.4.19 (Home: ~/.gnupg), awk 'awk version 20070501', grep 'grep (BSD grep) 2.5.1-FreeBSD', bash '4.3.42(1)-release (x86_64-apple-darwin14.5.0)'.

Answer 1

2016/04/25 更新:

从口是心非的 0.7.07.1 开始，与 python2-oauth2client 2.00 的不兼容性已得到修复(参见 changelog)。我刚刚在 Linux 机器上对其进行了测试，它运行良好。

原文如下:

首先，检查您的 python2-oauth2client 版本。在编写此版本时，2.00 似乎还不能与口是心非一起工作。我不得不降级回 1.5.2 以使其再次运行。

其次，确保没有由不同 python 版本引起的冲突(OSX 内置与自制程序包与手动安装与 pip 等)。专门使用自制软件可能是个好主意。

第三，确保你的pydrive配置完成。以下是如何使用“普通”Google 用户帐户执行此操作的简要说明:

第一步:创建pydrive后端配置文件

在某处创建一个 pydrive 配置文件(例如 /etc/duply/pydrive.conf 或 ~/etc/pydrive.conf)，内容如下:

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 可以从 Google Developers Console 的 API 管理器中获取在Google Drive API之后已启用。

• 将 save_credentials_file 设置为 pydrive 在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).

第 2 步:告诉口是心非在哪里可以找到它

这是通过设置 GOOGLE_DRIVE_SETTINGS shell 变量来完成的:

$ export GOOGLE_DRIVE_SETTINGS=/etc/duply/pydrive.conf

您可能想将它添加到您的 ~/.bashrc 以便所有 shell session 都自动设置它。

第三步:首次认证

引自口是心非的联机帮助页:

During the first run, you will be prompted to visit an URL in your browser to grant access to your drive. Once granted, you will receive a verification code to paste back into Duplicity. The credentials are then cached in the file references above for future use.

... 大功告成。

疑难解答

如果这仍然不起作用，请检查文件权限:运行口是心非的用户是否对上面指定的配置文件有足够的权限？
