最新找到的一个激活服务器，推荐大家使用激活服务器的方式激活，原因是这种方式简单快捷且没有过期时间。如果这种方式实在无法激活，可是使用下面的激活码方式激活。
服务器激活方式：
选择License server激活，然后填入：http://artemis.my.to，然后点Activate激活即可
----------------更新分割线2018.02.05----------------
激活码方式：
1.修改hosts文件：
添加下面一行到hosts文件，目的是屏蔽掉Pycharm对激活码的验证
- 0.0.0.0 account.jetbrains.com
windwos系统hosts文件路径为：C:\Windows\System32\drivers\etc
Linux和mac的hosts文件路径为：/etc
如果遇到权限问题，可将hosts文件先复制出来修改后再覆盖原来的即可。
修改后请检查hosts文件是否生效
修改后请检查hosts文件是否生效
修改后请检查hosts文件是否生效
2.打开PyCharm，选择 Activate code（用激活码激活）
3.在复制下载激活码，填入激活码框，点击 OK 进行认证。目前这个激活码有效期为：2018年10月14日

安装中遇到的问题
1.如果出现以下弹框，这说明你没有修改hosts文件，或说没生效
2.很多同学在微信公众号问我怎么项目运行不了，结果是因为大家在安装pycharm后没有为项目选择解释器，如图：
解决办法是：点击File->Setting->Project:your project name->Project Interpreter->右侧小圆圈->Add Local
也可以选择系统解释器，一样的。点击OK之后，如下，过一会就好啦
本教程的激活方式适用于JetBrains的全系列：IDEA、WebStorm、phpstorm等
