删除.pyc文件

find /tmp -name "*.pyc" | xargs rm -rf

查找pip3

which pip3 返回pip3的路径

将pip3赋值给pip，此时本地若是有pip2和pip3 重命名后pip被指向pip3

 alias pip=/usr/local/python3/bin/pip3

python2和python3 切换

ycharm4.5中安装了2.7和3.4版本的python，想让项目用2.7版本的python，去pycharm下找prefrnmence而不是file下的，这样就能解决问题了.
解释器的选项路径为：File->Setting->Build, Execution, Deployment-> Console-> Python Console:
将Python interpreter参数修改成你但愿的。就能够解决console中解释器（默认）版本。

External Libraries 修改方法为：File -> Settings->Project: "current Name当前项目名字" ->Project Interpreter->Python Interpreters，而后选择你但愿的版本，就能够解决系统模块的版本。
