问题对人有帮助，内容完整，我也想知道答案
问题没有实际价值，缺少关键内容，没有改进余地
犹豫了一段时间是否更新Mac OS X内置的Python2.7.5 最后在还是更新到了2.7.7版本然后一系列的问题来了。easy_install、pip、Scrapy、Django这些包都无法正常在终端下执行。
例如一哥们的的File "/usr/local/bin/pip", line 5, in &module&错误，我也检查了一遍。发现重装后也不可以，在PyCharm下将更新后的Python路径修复一下就可以正常使用了，但是非常奇怪的一点，无论我怎么卸载重装第三方包也好。就是不见Python的包在/Library/Python/2.7/site-packages/路径内，看到的只有之前内置2.7.5的包，就纳闷了半天还没想到问题。
想了一下执行比如easy_install的时候按照Windows的尿性还要加环境变量，那么我检查了一遍/usr/bin/目录是正常存在easy_install的。那么我在终端执行的结果是这样：
python version 2.7.7 can't run /usr/bin/easy_install.
Try the alternative(s):
(Error: no alternatives found)
Run "man python" for more information about multiple version support in
这样的问题我也检查了一遍，这个是原本未升级时2.7.5遗留下来的，并没有做过任何处理。
我在这里思考了一下，发现更新Python2.7.7之后所有的包都安装在了：/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/里面，我是不是认为我在更新完后执行easy_install的时候执行的并不是Python2.7.7里面的包？而是Python2.5.5里面的easy_install？
如果是这样，那么理论上我的解决方法是不是可以这样：将所有以前遗留的包软链接重新链接一次？
sudo rm -rf /usr/bin/easy_install
sudo ln -s /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/easy_install.py /usr/bin/easy_install
然后将以前的/Library/Python/2.7/site-packages/包删除掉？或者无视它的存在~
重点是，我将Python更新了，然后将包得软链接比如easy_install、pip、Django、Scrapy这样的包替换掉？是否就完美解决掉Mac OS X下的Python更新？
Ps.提问水平真的很拙计，希望大家能看得懂！

You should always use virtualenv as your python runtime.
pip install virtualenv
virtualenv env
source env/bin/active
If not, at least you should use pyenv:
