mac上IDLE打不开，提示IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall

在Mac上安装Python2.7后，启动IDLE后会报错。报错信息如下：

IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection.

修改如下，修改文件：
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/idlelib/pyshell.py

********
def main():
    global flist, root, use_subprocess
    use_subprocess = True
    enable_shell = True
    enable_edit = False
    debug = False
    ********

将use_subprocess = True修改为：
use_subprocess = False
代码在第1379行，可以用vi :set number显示行号
