python-3.x - 无法使用 pip 安装 sent2trash

Question

我尝试使用 pip 安装 send2trash 并收到以下错误消息:

$ 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.

当我尝试导入模块时，我收到以下错误消息:

ModuleNotFoundError: No module named 'send2trash'

也许问题是我使用的是 Python 3，而 pip 将其安装到了 Python 2.7 中。我不知道如何安装 send2trash 以便 python 3 使用它。

更新:

嗨，Marekful，感谢您尝试帮助我。我尝试了你的建议，但没有用

$ sudo pip install send2trash

Answer 1

我也遇到了同样的问题。确实是因为send2trash下载到了python2.7文件夹下。

(Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (18.0)). 

我刚刚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与 python3.7 对应的类似路径中版本:

/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages

现在它对我有用。希望这会有所帮助。

稍后编辑: 要在 Linux 和 Mac OS X 上的特定版本的 Python 中安装模块，请使用命令行中的 -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
