我正在尝试安装一个特定的 python 库（https://github.com/bitly/bitly-api-python/）。
推荐的方法是使用 pip，但是 pip 在我大学的认证代理系统后面不起作用。所以我正在尝试手动安装它。它有一个 setup.py 文件。我试着做sudo python setup.py install，它说：
running install
Checking .pth file support in /usr/local/lib/python2.7/dist-packages/
/usr/bin/python -E -c pass
TEST PASSED: /usr/local/lib/python2.7/dist-packages/ appears to support .pth files

bitly-api 0.2 is already the active version in easy-install.pth
Installed /usr/local/lib/python2.7/dist-packages/bitly_api-0.2-py2.7.egg
Processing dependencies for bitly-api==0.2
Finished processing dependencies for bitly-api==0.2
这看起来像一个成功的安装。但是，如果我说python然后import bitlyapi，python 说ImportError: No module named bitlyapi。
我究竟做错了什么？
