Unsupported Java Version: Cannot start under Java 1.7.0_151-b01: Java 1.8 or later is required.问题解决。

当我们在ubuntu 14.04下安装pycharm时，可能出现Unsupported Java Version: Cannot start under Java 1.7.0_151-b01: Java 1.8 or later is required.

解决方案：

• 添加apt-get源
  sudo vim /etc/apt/sources.list.d/java-8-debian.list

deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main

• 按ESC后输入:wq保存退出后执行
  sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys EEA14886
  sudo apt-get update.
  sudo apt-get install oracle-java8-installer

• 安装完毕，测试java版本：
  java –version

• Make as default
  sudo apt-get install oracle-java8-set-default

• 结束，可以安装pycharm了。
