Pipenv 中安装 Django

安装 Pipenv

​​Pipenv​​ 是一个生产流的工具，旨在将最好的打包世界（ bundler, composer, npm, cargo, yarn, etc. ）带入 Python 世界。它将 Pipfile、pip 和 virtualenv 整合到一个命令中。

我们可以使用 pip 命令安装 ​​ pip3 install --user pipenv​​：

$ pip3 install --user pipenv

为什么推荐使用 pipenv，因为它会自动为您的项目创建和管理虚拟环境 virtualenv，并在您安装/卸载包时从您的 Pipfile 中添加/删除包。它还生成非常重要的 Pipfile.lock，用于生成确定性构建。

安装 Django

创建一个项目文件夹 ​​mytodo​​ ：

$ mkdir mytodo
$ cd mytodo

​​Django​​ 是一个高级 Python Web 框架，它鼓励快速开发和简洁、实用的设计。它由经验丰富的开发人员构建，解决了 Web 开发的大部分麻烦，因此您可以专注于编写应用程序，而无需重新发明轮子。它是免费和开源的。

使用 ​​pipenv install django​​ 在虚拟环境中安装您的 django 框架：

$ sudo pipenv install django
