带pycharm的pycallgraph不起作用

Question

我正在使用mac x，并试图设置pycallgraph。

我用pip安装了pycallgraph，并用自制软件安装了graphviz。

一切都是从壳开始运作的。但不是来自侏儒。

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()

/Users/user/Projects/py27/bin/python /Users/user/Projects/py27_django/test2.py
Traceback (most recent call last):
  File "/Users/user/Projects/py27_django/test2.py", line 15, in <module>
    with PyCallGraph(output=graphviz, config=config):
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/pycallgraph.py", line 32, in __init__
    self.reset()
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/pycallgraph.py", line 53, in reset
    self.prepare_output(output)
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/pycallgraph.py", line 97, in prepare_output
    output.sanity_check()
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/output/graphviz.py", line 63, in sanity_check
    self.ensure_binary(self.tool)
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/output/output.py", line 96, in ensure_binary
    'The command "{}" is required to be in your path.'.format(cmd))
pycallgraph.exceptions.PyCallGraphException: The command "dot" is required to be in your path.

Process finished with exit code 1

在此：

/Users/user/Projects/py27/ ->虚拟环境

/Users/user/Projects/py27_django/ ->项目dir

它想要我做什么？

Answer 1

答案是：

在半月板：

Pycharm -> Run -> Edit Configurations...

在对话框中：

对于选定的.py文件或默认值/Python：

环境场组：

Environment variables > ... -> + ->

添加条目：

名称：PATH

价值：/usr/local/bin

应该选择Include print environment variables

Answer 2

使用以下方法在图形中安装MacOS：

brew install graphviz

或在Ubuntu中使用：

sudo apt-get install graphviz

然后，您可以使用以下方法测试点：

dot -v

您也可以从这里下载pkg。

FWIW，这是另外两个用户在PyCharm的bugtracker中作为问题提交的行为：https://youtrack.jetbrains.com/issue/PY-17816

如果开发者有评论的话，我会更新这篇文章。

2016年9月22日更新，Pycharm开发人员在早期访问版本中提供了一个修复程序。https://blog.jetbrains.com/pycharm/2016/09/pycharm-2016-3-eap-is-available-with-initial-support-for-python-3-6/，但这似乎还没有解决问题。
