本文针对：2016以下版本，2017版未测试：
内容如题，需要就参考一下，不需要请绕行！内容来自墙外我只是搬运工！
简单介绍一下步骤，本人是mac系统，所以使用linux系统的请自行区分路径：
1.下载下面的压缩包并解压下来。
http://idea.lanyus.com/jar/JetbrainsCrack-2.6.3_proc.jar
2.把JAR包复制到如下目录里。
/Applications/PyCharm.app/Contents/bin/JetbrainsCrack.jar
3.编辑一下文件， /Applications/PyCharm.app/Contents/bin/pycharm.vmoptions
填写如下内容：
-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=240m
-XX:+UseCompressedOops
-javaagent:/Applications/PyCharm.app/Contents/bin/JetbrainsCrack-2.6.3_proc.jar ##ps:这里配置补丁文件绝对路径
4.运行pycharm，并进行注册操作，输入注册码。
