WebStorm启动时遇到错误，由于6942到6991之间的50个端口被占用或防火墙限制导致失败。解决措施包括检查并释放被占用的端口或调整IDE绑定端口设置。

webstorm启动失败，报错如下：

原因：如果 6942 和 6991 之间的所有 50 个端口都被保留，被其他应用程序占用或防火墙不允许 IDE 绑定它们，则启动失败

解决方法：

1    netsh int ipv4 set dynamicport tcp start=49152 num=16383
2    netsh int ipv4 set dynamicport udp start=49152 num=16383

如果上面方法没有效果，尝试如下命令：

1    net stop winnat
2    net start winnat
