我是python的新手（不是Mac OS X）。我想安装一个似乎已安装的软件包（此处：blink1），但我无法使用它。也许这与我的Mac上的几个版本有关，但这里提供的所有解决方案仍然不起作用。任何帮助表示赞赏。
我通过pip安装了包：
sudo pip install blink1
Requirement already satisfied (use --upgrade to upgrade): blink1 in /Library/Python/2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): pyusb>=1.0.0b1 in /Library/Python/2.7/site-packages/pyusb-1.0.0b1-py2.7.egg (from blink1)
Requirement already satisfied (use --upgrade to upgrade): click in /Library/Python/2.7/site-packages (from blink1)
Requirement already satisfied (use --upgrade to upgrade): webcolors in /Library/Python/2.7/site-packages (from blink1)
Cleaning up...
然后运行python给出
Python 2.7.6 (default, Sep 9 2014, 15:04:36)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
>>> from blink1.blink1 import blink1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named blink1.blink1
我的syspath如下
['', '/Library/Python/2.7/site-packages/pip-1.4.1-py2.7.egg',
'/Library/Python/2.7/site-packages/pyusb-1.0.0b1-py2.7.egg',

我使用的是Mac OS X 10.10.1。
