from pycallgraph import PyCallGraph from pycallgraph import Config from pycallgraph import GlobbingFilter from pycallgraph.output import GraphvizOutput config = Config() config.trace_filter = GlobbingFilter(exclude=[ 'pycallgraph.*', ]) graphviz = GraphvizOutput(output_file='filter_exclude.png') with PyCallGraph(output=graphviz, config=config): def my_fun(): print "HELLO" my_fun()

这里:/Users/user/Projects/py27/ -> virtualenv 目录/Users/user/Projects/py27_django/ -> 项目目录

Here: /Users/user/Projects/py27/ -> virtualenv dir /Users/user/Projects/py27_django/ -> project dir

它想从我这里得到什么?

What does it want from me?

推荐答案

答案是:

在菜单栏中:Pycharm -> 运行 -> 编辑配置...

In menubar: Pycharm -> Run -> Edit Configurations...

在对话框中:对于选定的 .py 文件或 Defaults/Python:

In dialog: for selected .py file or for Defaults/Python:

环境字段组:

环境变量 > ... -> + ->添加条目:名称:PATH值:/usr/local/bin

应选择包含打印环境变量
