原文地址：https://www.shuopython.com/archives/2792
Pycharm 下载和安装请参考：Python 环境配置 ，当前版本是2017.2可能安装的时候有点早，目前最新版本已经是2019版本了，所以当时文章的激活码应该都过期了，下面这个激活码可以用到2089年，亲测可用：

二.Pycharm 永久激活
Pycharm 永久激活请参考：Pycharm 永久激活码 ，建议小伙们在激活之前，先看看下面 Pycharm 配置错误导致无法启动的问题 在继续激活操作！
激活方式分两种：
第一种补丁激活：补丁激活的时候必须是 Pycharm 版本和 jar 补丁版本一致，如果 Pycharm 是2019版本那么就用2019的jar版本，如果如果 Pycharm 是2017版本那么就用2017的jar版本
pycharm 2017.3补丁下载：提取码：of3h
pycharm 2019.3补丁下载 ：提取码： quwe
第二种激活码激活：激活码前面已经给出了
三.Pycharm 配置错误无法启动
很多小伙伴都留言说修改了配置（“Help” -> “Edit Custom VM Options …”）之后，Pycharm 都启动不了了，此时，我总感觉自己要被砍，只能瑟瑟发抖，别问我在哪？？
1.Pycharm 无法启动的原因
100%是因为在配置补丁的时候，配置信息填写错误！！一个空格都不能错！！！一旦出错，pycharm无法正常启动！！如果pycharm版本和jar补丁版本不一致也有可能造成这个问题！！！
打开Pycharm 选择顶部菜单： “Help” -> “Edit Custom VM Options …” 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
2.Pycharm 无法启动，重新还原配置文件
A.由于我们在配置的过程中，错误的修改了配置文件 或者 Pycharm与jar补丁版本不一致，造成 Pycharm 无法启动，那么我们只需要将配置文件还原即可，找到对应的配置文件：
|
1
2
|
//Mloong 是我的计算机用户名
C:UsersMloong.PyCharm2017.3configpycharm64.exe.vmoptions
|
B.编辑配置文件,删除配置文件最后一行
C.保存，关闭，重启 Pycharm
