我想安装一个名为的 Python 包imagehash。我尝试使用 pip 安装，但出现异常：
Requirement already satisfied (use --upgrade to upgrade): imagehash in /usr/local/lib/python3.4/dist-packages
Downloading/unpacking scipy (from imagehash)
Downloading scipy-0.15.1.tar.gz (11.4MB): 4.2MB downloaded
Cleaning up...

我想在 python2 上使用这个模块，但它似乎正在为 python 3 编译，我输入sudo pip install imagehash
