本人想安裝python用的dlib和face_recognition元件，但是真想說xxx，網上說了很多辦法，什麼anaconda，cmake編譯boost。。。

可能我這裡的版本不一樣吧，我現在用的是win7 64bit python2.7 visual studio2010，用pip安裝

pip install dlib
pip install face_recognition

全是報錯誤

Running setup.py bdist_wheel for dlib ... error

。。。
Failed building wheel for dlib
Running setup.py clean for dlib

本人是visual studio 2010 老是提示更新安裝2015，不想安裝，2010用的挺好的，再說以前的好多工程都是2010搞得，怕升到2015相容不好，就麻煩了，於是乎我就利用網友的辦法，什麼anaconda 、cmake。。。 總之一步十個跪，最終經過兩天的折磨還是妥協了。。。

用半個小時時間裝完2015，在pip install face_recognition 竟然ok了。好想罵人。。。

這裡mark一下：有時候還是要尊重錯誤提示，有時候錯誤日誌提示可能對你來說不是最好的解決方法，但是可能確實最快的。

ps：更新完成face_recognition 和dlib  就把2015 卸掉了，哈哈哈
