在使用使用pycharm是很方便，但是由于注册pycharm的时候是用激活码注册的，所以到期了。
由于注册码到期了，所以需要重新激活。下面是注册步骤：
在C:\Windows\System32\drivers\etc中的有个hosts文件，打开在最后加上下面的代码
0.0.0.0 account.jetbrains.com
（网上有人说注意以下末尾得加上个空格）
末尾处就是这样。
下面然后就在http://idea.lanyus.com/去拿到激活码。但是由于今天这网站太卡了，估计很多人都到期了，所以服务器爆了。
然后在网上找到激活码，如下：

然后打开pycharm，enter license 选择active code 输入上面的激活码。到2020.3.11就到期，估计到时有的重新重复上面的步骤，重新激活。
