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
