Python IDLE's subprocess didn't make connection

Win7 上安装Python 2.7.1，启动IDLE报错。

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

google 了一下。解决方案惊人的一致，大概都是修改\Lib\idlelib的run.py

照做，无效。

自己分析，貌似和firewall有关，遂关闭firewall,顺利开启IDLE。
