pycharm不联网能运行吗_pycharm连接调试器失败

Jetbrains全系列IDE使用 1年只要46元 售后保障 童叟无欺

第一步：查看你的计算机是否安装了严密的防火墙，当你开始运行编写的网络程序时他都会发出警告并且禁止你的程序连接网络你要对防火墙进行配置，让他允许你的程序或者直接关闭防火墙(慎重考虑)如下图

直接关闭防火墙

或者对防火墙进行设置(只要选中这两个勾，在你执行的时候会提示你是否允许XXX连接网络)

第二步：因为有些代码里面可能需要根据主机名称来去本地的DNS里找对应的IP地址，由于本地的DNS配置中没有指定主机名这个IP地址是什么，也就会提示无法连接或者连接超时，打开终端输入命令cat /private/etc/hosts，如下图：

然后编辑主机配置，增加主机名的映射，输入命令sudo vi /private/etc/hosts，进入VI编辑器(i进入编辑模式)，写如下代码：

如果出现下图的状况回车就可以了

和你当前网络的IP(因为有的人可能连接的别的设备等)        你的主机名称

摁Esc然后输入:wq!退出VI编辑器并且保存

然后输入刷新命令dscacheutil -flushcache

这样问题就解决了，希望对大家有所帮助
