第二步: 修改hosts文件，windows的hosts路径是 C:\Windows\System32\drivers\etc\hosts ，mac 的hosts路径是：/etc/hosts

image
0.0.0.0 account.jetbrains.com
0.0.0.0 www.jetbrains.com
注：有些windows没权限直接在drivers\etc目录下修改hosts文件，可以先把hosts文件复一份到桌面修改，然后然后用桌面的hosts文件去drivers\etc目录下的hosts。
注：有朋友向我反映hosts新添加的最后一行，会被注释掉，这个是因为360 或者电脑管家的安全扫描会扫描到你的hosts文件异常，然后给添加上注释。建议关闭安全软件的文件防护系统，然后修改，修改完之后再打开文件防护系统。
