python汇 安装问题
问题1：
Could not find any downloads that satisfy the requirement XStatic-Angular-Irdragndrop>=1.0.2.1 (from horizon==2015.1.dev110)
Some externally hosted files were ignored as access to them may be unreliable (use --allow-external XStatic-Angular-Irdragndrop to allow).
No distributions at all found for XStatic-Angular-Irdragndrop>=1.0.2.1 (from horizon==2015.1.dev110)
解决：
1 查看安装包目录/usr/local/lib/python2.7/dist-packages/，其它包已安装好
XStatic-1.0.1-py2.7.egg-info XStatic-1.0.1-py2.7-nspkg.pth XStatic_Angular-1.3.7.0-py2.7.egg-info XStatic_Angular-1.3.7.0-py2.7-nspkg.pth XStatic_Angular_Bootstrap-0.11.0.2-py2.7.egg-info XStatic_Angular_Bootstrap-0.11.0.2-py2.7-nspkg.pth2 使用 pip install XStatic-Angular-Irdragndrop也不能安装成功
3 在3月31日时XStatic-Angular-Irdragndrop包(I为大写的i)在pypi中不存在，只存在一个XStatic-Angular-lrdragndrop 1.0.2.2包，同时在https://pypi.python.org/simple/中也不存在。第二天查看pypi时，已经有包 XStatic-Angular-Irdragndrop：
XStatic-Angular XStatic-Angular-Animate XStatic-Angular-Bootstrap XStatic-Angular-Cookies XStatic-Angular-FileUpload XStatic-Angular-IrDragNDrop XStatic-Angular-lrdragndrop XStatic-Angular-Mock
