模块未发现错误：VS 代码中没有名为'flask'的模块

Question

当我在VS Code中运行时，它可以正常工作，没有错误

from werkzeug.wrappers import Request, Response
from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
return "Hello World!"

if __name__ == '__main__':
from werkzeug.serving import run_simple
run_simple('localhost', 9000, app)

在这里查看它在我的终端上的工作方式。

127.0.0.1 - - [21/May/2020 17:45:42] "GET /favicon.ico HTTP/1.1" 404 -

但是，当我在VSCode终端中编写它时...

ModuleNotFoundError: No module named 'flask'

Conda 中的相同命令：

(base) C:Windowssystem32>python

>>> from flask import Flask, request, jsonify
>>> import flask
>>>

为什么会发生这种情况，我该如何解决这个问题？

如果你也在使用Visual Studio，也许VSCode没有使用正确的python解释器。您可以尝试在VSCode中选择屏幕左下角的conda解释器。
