写在前面：
以前安装过python3的环境，然后也安装过pycharm，好长时间不用了，今天用发现过期了，所以就网上搜了一些激活码的方式，还是蛮管用的。

做python开发，绝大部分童鞋都是使用pycharm，不管是第一次配置环境或者pycharm已经使用一段时间，早晚都会出现如下问题：激活到到期啦，怎么办？
pycharm 永久激活:
1.下载补丁
点击链接 链接: https://pan.baidu.com/s/159Drdy039wFEnzyaf4uQ6w 提取码: giw5 ， 下载补丁文件 jetbrains-agent.jar 并将它放置到 pycharm安装目录的in目录下（位置可随意，放这里是怕误操作删除了破解文件）
2.进入项目界面
需要点击激活窗口的“Evaluate for free”免费试用，然后再创建一个空项目，这样就可以进入到pycharm的工作页面
3.修改配置文件
点击Pycharm最上面的菜单栏中的 “Help” -> “Edit Custom VM Options …”，如果提示是否要创建文件，请点”Yes”。
在打开的vmoptions编辑窗口末行添加：
|
1
|
-javaagent:你pycharm的安装目录jetbrains-agent.jar
|
例如：-javaagent:G:PyCharm 2017.3.2injetjetbrains-agent.jar
4.输入激活码
重启pycharm之后，点击菜单栏中的 “Help” -> “Register …”，这里有两种激活方式：
方案A：选择最后一种License server激活方式，地址填入：http://jetbrains-license-server （应该会自动填上），或者点击按钮：”Discover Server”来自动填充地址，完成激活
如果激活失败提示：No free ticket available，请使用方案B；
方案B：选中 Activation code输入激活码
激活码如下：

5.查看有效期
方案A：启动pycharm
方案B：启动pycharm之后，点击菜单栏中的 “Help” -> “Register …”
很多小伙伴说，修改了配置文件，连pycharm都启动不了了，解决办法请参考：Pycharm 永久激活 – 无法启动的解决办法
