可能是什么問題呢？？ Python 版本：3.8.5 點：20.1.1

Answer 1

第 2 步 — 安裝 Python 1.sudo apt-get update && sudo apt-get -y upgrade 2.sudo apt-get install python3。 3.sudo apt-get install -y python3-pip。

步驟 2 — 安裝 virtualenv 1.pip3 install virtualenv。 2.virtualenv --version。

第 3 步 - 安裝 Django

選項 1：在 virtualenv 中安裝 Django。 當您需要將您的 Django 版本與服務器的全局環境隔離時，這是理想的選擇。

選項 2：從源代碼安裝 Django。 如果您想要最新的軟件或想要比您的 Ubuntu APT 存儲庫提供的軟件更新的軟件，您可以直接從源代碼安裝。 請注意，如果您希望您的軟件版本是最新的，則選擇這種安裝方法需要持續關注和維護。

選項 3：使用 pip 全局安裝 Django。 我們要使用的選項是 pip 3，因為我們將在全局安裝 Django。

第 4 步 1.mkdir django-apps 2.cd django-apps 3. 激活 virtual.=> virtualenv env 4.. env/bin/activate 5.pip install django

步驟 4 — 創建 Django 測試項目 1.django-admin startproject testsite 2.cd testsite 3.ls 4.manage.py runserver
