"IDLE's subprocess didn't make connection. "的解决方法

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

这个问题的解决方法是：

打开所在安装目录下的 ../Lib/idlelib/PyShell.py 大约在1400行左右，将use_subprocess = True 改为 use_subprocess = False

同时删除PyShell.pyc便可。
