1.运行PyCharm时报错如下：

出现问题：ModuleNotFoundError: No module named 'utils’

1、（macos系统下）点击PyCharm -- Prefereces

2、点击Project:xxx -- Project Interpreter 后，点击+ 。（xxx为当前你的项目名称）

3、输入需要的模块名称查找，以utils 为例，点击utils后，点击install Package

在shell下运行python脚本报错：

出现问题：ModuleNotFoundError: No module named 'utils’

解决方法：

python2安装

pip install web.py

python3安装

pip install web.py==0.40-dev1

电脑python版本3.7，按照python3安装报错如下：（解决方案在后面）

于是尝试按照python2的安装，成功。
