Cleaning up...按照上诉提示，执行下面命令
$pip install pyinstaller --upgrade
Exception:

Storing debug log for failure in /home/admin/.pip/pip.log还是报错，根据最后一句，缺少权限，所以
$sudo pip install pyinstaller --upgrade
Uninstalling altgraph:
Successfully uninstalled altgraph
Successfully installed pyinstaller setuptools altgraph
Cleaning up...安装成功了，查看一下版本
$pyinstaller --version
