我尝试使用pip安装send2trash并收到以下错误消息：

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.
当我尝试导入模块时，出现以下错误消息：
ModuleNotFoundError: No module named 'send2trash'
也许问题是我正在使用Python 3，并且pip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。
更新：
嗨，Marekful，谢谢您的帮助。我尝试了您的建议，但没有用
$ sudo pip install send2trash

最佳答案
我有同样的问题。确实是由于send2trash已下载到python2.7文件夹中这一事实。
(Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (18.0)).
我只是进入该文件夹，并将名为
send2trash和Send2Trash-1.5.0.dist-info的两个文件夹复制到对应于python3.7版本的相似路径中：/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages
现在对我有用。希望这可以帮助。
以后编辑：
要在Linux和Mac OS X的特定版本的Python中安装模块，请在命令行中使用-m开关：
python2 -m pip install SomePackage # default Python 2
python2.7 -m pip install SomePackage # specifically Python 2.7
python3 -m pip install SomePackage # default Python 3
python3.4 -m pip install SomePackage # specifically Python 3.4
