一、Flask

参见 ： 安装 — Flask 0.10.1 文档

1、sudo apt-get install python3-pip

2、sudo pip3 install Flask

二、入门

快速入门 — Flask 0.10.1 文档

编写app.py

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello World!'

if __name__ == '__main__':
    app.run()

python3 app.py

提示错误，找不到库

Traceback (most recent call last):
  File "/home/robot/flask-test/app.py", line 1, in <module>
    from flask import Flask
ModuleNotFoundError: No module named 'flask

我用的anaconda虚拟环境。所以：

pip uninstall Flask && python3 -m pip install flask

然后重新执行

(yolov5) robot@robot-All-Series:~/flask-test$ python3 app.py
