如何在 google colab notebook 上执行 '!pip install tr​​ee' 后使 '!tree' 工作？

Question

我!pip install tree在 google colab notebook 上做过。它表明Pillow in /usr/local/lib/python3.6/dist-packages (from tree) (4.3.0). 但是当我使用!tree. 笔记本提醒了我bin/bash: tree: command not found。如何解决？

我尝试了几次，但都失败了。

!pip install tree
!tree

我希望它显示目录中文件的结构。

您似乎将 pip 与本地包管理器混淆了？

!apt-get install tree 做你想做的事：
