输出cat /etc/environment：

你应该编辑你的/etc/环境使用文本编辑器并添加最后一个引号 ( ")。
例如使用 Nano：
sudo nano /etc/environment
改变
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/java/jre1.8.0_171/bin"
JAVA_HOME="/usr/java/jre1.8.0_171
到
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/java/jre1.8.0_171/bin"
JAVA_HOME="/usr/java/jre1.8.0_171"
按Ctrl+O保存，然后按Ctrl+X退出。
