一种永久破解的方法。

　　破解补丁激活。

　　1.下载  并将 JetbrainsCrack-release-enc.jar 放置到 pycharm安装目录的\bin目录下。比如，我放在了C:\Program Files\JetBrains\PyCharm 2018.3.1\bin目录下。

　　2.在 Pycharm安装目录的\bin目录下找到 pycharm.exe.vmoptions 和 pycharm64.exe.vmoptions文件，以文本格式打开并在两个文件最后都追加  -javaagent:你pycharm的安装路径\bin\JetbrainsCrack-release-enc.jar，注意路径修改成你的pycharm安装路径，然后保存。比如我追加的内容是-javaagent:C:\Program Files\JetBrains\PyCharm 2018.3.1\bin\JetbrainsCrack-release-enc.jar

　　3.启动Pycharm ,选择激活码激活，输入如下内容激活
