请帮忙

Answer 1

命令是

sudo pip install django==3.0.1

pipenv不是有效的命令

检查安装时的Django文档。 它提供了一个循序渐进的指令，选择所需的操作系统

关于sudo呢

The sudo command allows you to run programs with the security privileges of another user (by default, as the superuser). It prompts you for your personal password and confirms your request to execute a command by checking a file, called sudoers, which the system administrator configures.
