Flask框架
Flask框架中文网
建议在开发环境和生产环境下都使用虚拟环境来管理项目的依赖。虚拟环境可以为每一个项目安装独立的 Python 库，这样就可以隔离不同项目之间的 Python 库，也可以隔离项目与操作系统之间的 Python 库。
如果你使用Python 3版本，可以按以下方式配置虚拟环境和Flask环境。
创建虚拟环境
创建一个项目文件夹
cd 文件夹路径
mkdir myproject
cd myproject
python3 -m venv venv
pip3 install virtualenv
如果此时提醒诸如
WARNING: You are using pip version 22.0.4; however, version 22.1.2 is available.就按照提示升级PHP版本。
在Windows下
py -3 -m venv venv
Python27\Scripts\virtualenv.exe venv
pip3 install Flask
激活虚拟环境
. venv/bin/activate
在Windows下
> venv\Scripts\activate
安装Flask
在已激活的虚拟环境中可以使用如下命令安装 Flask：
pip install Flask
SQLite
前往SQLite下载或SQLite中文下载载预编译的二进制文件。Windows系统请下载
基于您的电脑选择适用于32位或64位的文件。
创建文件夹 C:\sqlite，并在此文件夹下解压上面两个压缩文件，将得到以下文件：
添加 C:\sqlite 到 PATH 环境变量
运行 sqlite3
