无法导入模块sent2trash在Python

Question

我做了一个点子安装send2trash的，这是我得到的消息：

Admins-MacBook-Pro-2:~ kylefoley$ pip install send2trash

You are using pip version 7.1.2, however version 9.0.1 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command. 

当我尝试使用send2trash我得到ModuleNotFoundError：无模块名为“send2trash”

也许问题是我正在使用python 3并将其安装到python 2.7中。我不知道如何安装send2trash，以便python 3使用它。

构建成功，但安装失败，由于权限问题。

OSError: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/send2trash'

与sudo运行命令：

Admins-MacBook-Pro-2:~ kylefoley$ sudo pip install send2trash
