本人python菜鸟，请各位多多指点。
If you already have PATH, just use python.Or try using slashes instead of backslashes.
You have not entered the folder of the run.py program at all.Learn how to enter the folder using cmd
Install virtualenv and run in virtualenv environment
If you already have PATH, just use python.Or try using slashes instead of backslashes

Install virtualenv flask under win8.1 python3.4.2Error when executing flask/Scripts/python run.py

In addition, whether run.py should be outside the app directory is more standardized
