2.2 安装
root@darren-virtual-machine:~/Downloads/pycharm-2019.3.4/bin# sh ./pycharm.sh
出现Complete-Installation提示框，如图5，如果需要导入之前安装版本的配置的话，就选第一个，没有就选第二个。所以这里选第二个，直接点OK，
弹出 PyCharm Privary Policy Agreement，隐私政策协议框，点击Continue
选择跳过
先使用免费30的，后面再激活
安装完成
2.3 创建桌面快捷方式
root@darren-virtual-machine:~/Desktop# touch pycharm.desktop
root@darren-virtual-machine:~/Desktop# vim pycharm.desktop
[Desktop Entry]
Encoding=UTF-8
Name=pycharm
Exec=sh /root/Downloads/pycharm-2019.3.4/bin/pycharm.sh
Icon=/root/Downloads/pycharm-2019.3.4/bin/pycharm.png
Info="Spark"
Terminal=false
Type=Application
StartupNotify=true
root@darren-virtual-machine:~/Desktop# chmod 700 pycharm.desktop
点击桌面图标文件，并添加信任，结果如下
三 ubuntu安装python3
