什麼是pipenv

pipenv是requests做者的一個項目, 整合了virtualenv, pip, pipfile, 用於更方便地爲項目創建虛擬環境並管理虛擬環境中的第三方模塊.
虛擬環境能夠隔離各類python項目所須要的不一樣的環境，能夠利用python2和python3分別建立虛擬環境，同時運行python2,3的項目

環境：

python3.6.4
win10

安裝pipenv

啓動win10終端，命令行輸入 pip install pipenv ,過程大概須要一兩分鐘，具體網絡狀況而定
安裝完成顯示：

給項目安裝虛擬環境

進入項目目錄下面（安裝pipenv的時候是在全局安裝，此時安裝項目虛擬環境須要到你的項目目錄下面安裝）
輸入命令： pipenv install
安裝完成後顯示：

To activate this project's virtualenv, run the following: $ pipenv shell 複製代碼

激活虛擬環境

輸入命令： pipenv shell （退出命令：exit）
一兩秒後完成顯示：

激活以後就能夠在虛擬環境裏面搭建項目所須要的環境，安裝各類包了，下面以flask爲例

安裝flask

進入虛擬環境以後，輸入命令：pipenv install flask
過程大概十秒左右，完成後顯示：
