我尝试使用 python3-pip 安装 Django，当我运行

在 Ubuntu 16.04 及更高版本中，您不需要使用 pip3 安装 Django，因为 Django 位于默认存储库中。打开终端并输入：

sudo apt update  
sudo apt install python3-django    

如果您仍想使用 pip3 安装 Django，则应将 pip3 更新到最新版本，以便 pip3 能够安装 Django 及其依赖项。运行以下命令：

sudo python3 -m pip install --upgrade pip  
sudo python3 -m pip install django  

您可以通过输入以下命令来验证安装是否成功：

django-admin --version
