初次使用Flask,可以正常引入，但是运行时报错from flask import Flask

Question

from flask import Flask

app = Flask(name)

@app.route('/')
def hello_world():
return '泥豪，世界！'

if name == "main":
app.run(host='127.0.0.1', port=8080)

运行结果：
D:\publicdemo\venv\Scripts\python.exe D:/publicdemo/testcase/test_api.py
Traceback (most recent call last):
File "D:/publicdemo/testcase/test_api.py", line 1, in
from flask import Flask
File "D:\publicdemo\venv\lib\site-packages\flask_init_.py", line 1, in

ModuleNotFoundError: No module named 'markupsafe'
