python网站项目，直接运行找不到flask

已经安装了flask,为什么提示找不到flask呢？(已安装 flask 3.0.0，宝塔面板8.0.5，通过网站-python项目添加的)

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

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "<p>Hello, World!</p>"
