Answer 1

Thank you everyone for your answers.
It has been solved. You need to import the flask path in the virtual environment. Here is export PYTHONPATH=$PYTHONPATH:/root/FlaskWebDevelopment/venv/lib/python2.7/site-packages;

Answer 2

You can configure the log of [program:app] first, and then determine from the log the specific reason why it failed to start successfully.
The log configuration is as follows:

[program:app]
stdout_logfile=/path/app.log
stderr_logfile=/path/app.log

Answer 3

Use an absolute path for source, and virtualenv is not active, causing the python environment that your command runs to not have flask installed.

Answer 4

Original, import flask failed, check if flask is installed
pip install flask
