一、下载pycharm
（1）进入官网下载Download PyCharm: The Python IDE for data science and web development by JetBrains
选择专业版（professional）直接点击下载（download），我下载的是2023.3.5版本。
（2）进行本地解压
-------------------------------------------先不要安装，为后面做准备工作------------------------------------------
二、重置PyCharm（新安装的不需要）
（1）打开scripts文件夹，选择uninstall.sh文件运行（ubuntu用户选择这个，windows用户选择.vbs）
运行：
sh ./uninstall.sh(这个文件是卸载文件)
出现提示Done，即运行成功。
（2）运行install.sh文件
如果运行失败，请检查scripts及上级文件路径是否有中文，必须保证路径全英文。
提示Done即运行成功。
三、修改pycharm64.vmoptions文件
使用vim打开文件，加入以下内容：
其中第一行的地址需要修改为自己ja-netfilter.jar文件所在绝对路径，前面的-javaagent不能修改。
-javaagent:/Downloads/jetbra/jetbra/ja-netfilter.jar
--add-opens=java.base/jdk.internal.org.objectweb.asm=ALL-UNNAMED
--add-opens=java.base/jdk.internal.org.objectweb.asm.tree=ALL-UNNAMED
三、修改hosts文件
命令窗口输入：
sudo gedit /etc/hosts在里面添加：
0.0.0.0 account.jetbrains.com
四、PyCharm
（1）进入到下载包的bin文件夹里面
cd /Downloads/pycharm-professional-2023.3.5/pycharm-2023.3.5/bin（2）执行pycharm.sh文件，开始安装
sh ./pycharm.sh（3）选择Activation Code方式
输入注册码，然后点击“Activate”即可。
注册码在这个文件内：
注：这里第一次用注册码我操作成功了但是马上又让重新输入，然后换了其他的，附在下面，大家可以尝试一下：

五、添加桌面快捷方式
在/usr/share/applications创建一个文件：pycharm.desktop
输入以下内容：
cd /usr/share/applications
sudo gedit pycharm.desktop
[Desktop Entry]
Version=1.0
Type=Application
Name=Pycharm
Icon=/Downloads/pycharm-professional-2023.3.5/pycharm-2023.3.5/bin/pycharm.png
Exec=sh /Downloads/pycharm-professional-2023.3.5/pycharm-2023.3.5/bin/pycharm.sh
MimeType=application/x-py;
Name[en_US]=pycharm下面两句修改成自己的路径：
Icon=/Downloads/pycharm-professional-2023.3.5/pycharm-2023.3.5/bin/pycharm.png
Exec=sh /Downloads/pycharm-professional-2023.3.5/pycharm-2023.3.5/bin/pycharm.sh
