二、Pycharm 2019 破解補丁激活方法步驟
使用破解補丁方法雖然麻煩，但是可用激活到2099年，基本上是永久激活了，畢竟在座各位能活到這個年份也是寥寥無幾了吧！！
步驟一、首先下載 Pycharm 2019版本： https://download.jetbrains.8686c.com/python/pycharm-professional-2018.3.3.exe。
然后下載破解補丁，https://pan.baidu.com/s/1mcQM8CLUnweY02ahKEr4PQ 。
將破解補丁文件 JetbrainsCrack-release-enc.jar 放置到 pycharm 程序安裝目錄\bin目錄下。
步驟二、在 Pycharm軟件安裝目錄的\bin目錄下找到 pycharm.exe.vmoptions 和 pycharm64.exe.vmoptions 兩個文件 ，右鍵以文本格式打開（可用借助Notepad打開），在兩個文件最后追加 -javaagent:盤符:\你的pycharm的安裝路徑\bin\JetbrainsCrack-release-enc.jar，這里一定要把你的pycharm安裝路徑寫正確，失敗都是因為這步沒有做好，然后保存即可。
步驟三、啟動Pycharm軟件 ,選擇激活碼激活，輸入下面內容即可永久激活了！
