VScode 搭建 django 开发环境（Win Python3.71 django1.11.11）

Posted 2021-11-28 williamb

• 全新Win10下安装开发环境记录
• 安装VScode
• 安装Git
• 安装Python3.71
• VScode安装好相关插件
• 新建好文件夹用 VScode 打开
• code-终端-新建终端
• 要创建虚拟环境，请使用以下命令，其中“env”是环境文件夹的名称：

1 py -3 -m venv env

• 进入虚拟环境文件夹

cd env

• 安装指定版本DJango

pip3 install django==1.11.11

• 安装依赖

pip3 install pylint pylint_django

• 输出已安装了 Django 和运行着的版本号

python -c "import django; print(django.get_version())"

• 新建项目mysite

django-admin.py startproject mysite

• 出错：VSCode直接弹出django-admin.py，因为设置了VSCode为.py文件的打开方式，改为Python,exe
• 进入mysite项目文件夹(项目 mysite下还有个 mysite文件夹)

cd mysite

• 创建名为polls的APP

python manage.py startapp polls

• 出错，错误代码：

• 打开28行代码的文件

  C:\\Users\\William\\AppData\\Local\\Programs\\Python\\Python37\\lib\\site-packages\\django\\contrib\\admin\\widgets.py

• 找到152行，删掉,号保存文件，重新运行  ‘创建名为polls的APP’ 的代码

• 以指定端口8001运行Django

python manage.py runserver 8001

• 打开http://127.0.0.1:8001/看见如下内容即为搭建成功

It worked!

Congratulations on your first Django-powered page.

Next, start your first app by running python manage.py startapp [app_label].

You‘re seeing this message because you have DEBUG = True in your Django settings file and you haven‘t configured any URLs. Get to work!
