我的操作系统是 ubuntu 18.04，我安装了 Android-Studio 3.4 sudo apt ~，每次运行终端时都会收到此消息。因此，我卸载了 Android-Studio，希望此消息消失。然后我再次使用内置安装程序“Ubuntu Software”安装 Android-Studio。但是，我仍然收到此消息：
Android: command not found.
此外，我的联想（8 GB 内存）笔记本电脑在 Android-Studio 上很容易冻结。
以下是 inxi -Fxx 的输出：

有人可以帮我让这个消息（Android: command not found）消失吗？
- 感谢对 raz0r 的评论：我
Can you check /etc/profile and your ~/.bashrc?在这里添加它，因为它太长，无法添加为评论。
的输出tommy@tommy-lenovo:~$ cat /etc/profile是：
