requirements.txt 文件的兼容
pipenv可以像virtualenv一样用命令生成requirements.txt 文件：
pipenv lock -r > requirements.txt # 将Pipfile和Pipfile.lock文件里面的包导出为requirements.txt文件
pipenv lock -r --dev > requirements.txt # 将Pipfile和Pipfile.lock文件里面的开发包导出为requirements.txt文件
pipenv 通过requirements.txt安装包：
pipenv install -r requirements.txt
pipenv install -r --dev requirements.txt # 只安装开发包
Python 文件的运行
方式一： pipenv run python xxx.py
pipenv run python xxx.py
方式二：在激活环境中运行
#进入激活环境
pipenv shell
#运行文件
python xxx.py

In order to keep your environment consistent, it’s a good idea to “freeze” the current state of the environment packages. To do this, run:
$ pip freeze > requirements.txt
$ pip install -r requirements.txt

要想在python3下成功import cv2，则
sudo apt install python3-pip
sudo apt install libopencv-dev
sudo pip3 install opencv-python
