先查看现有版本，然后安装了python3.3，并将其设置为默认版本。

jaydeMacBook-Pro:Versions jay$ ls /System/Library/Frameworks/Python.framework/Versions/2.3 2.5 2.6 2.7 Current

下载python-3.3.3-macosx10.6.dmg并打开完成安装。

jaydeMacBook-Pro:Versions jay$ sudo mv /Library/Frameworks/Python.framework/Versions/3.3 /System/Library/Frameworks/Python.framework/VersionsPassword:jaydeMacBook-Pro:Versions jay$ cd /System/Library/Frameworks/Python.framework/Versions/jaydeMacBook-Pro:Versions jay$ ls2.3 2.5 2.6 2.7 3.3 CurrentjaydeMacBook-Pro:Versions jay$ cd ~jaydeMacBook-Pro:~ jay$ vi .bash_profile

增加：

alias python="/System/Library/Frameworks/Python.framework/Versions/3.3/bin/python3.3"

jaydeMacBook-Pro:~ jay$ source .bash_profile

.bash_profile 文件是之前配置sdk时创建的，“source .bash_profile”是让变更生效（重新打开终端效果一样）。

jaydeMacBook-Pro:~ jay$ pythonPython 3.3.3 (v3.3.3:c3896275c0f6, Nov 16 2013, 23:39:35) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwinType "help", "copyright", "credits" or "license" for more information.>>> >>> >>> >>> exit()jaydeMacBook-Pro:~ jay$

pycharm可以选择已安装的版本，设置方式：
preferences > Project:xxxxx > project interpreter
