vscode无法导入文件

Question

我刚开始使用 vscode，我正在尝试从同一目录中的其他文件导入导入表单和类，但由于某种原因它无法正常工作。它在 pycharm 中工作，所以我复制了所有代码。

这是我要导入的主文件：

from flask import Flask, render_template, url_for, flash, redirect
from flask_sqlalchemy import SQLAlchemy
from forms import RegistrationForm, LoginForm
from models import User, Post

forms.py

from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField, BooleanField
from wtforms.validators import DataRequired, Length, Email, EqualTo

class RegistrationForm(FlaskForm):
    username = StringField('Username',
                           validators=[DataRequired(),
                           Length(min = 2, max=20)])
    email = StringField('Email',
                        validators=[DataRequired(), Email()])
    password = PasswordField('Password', validators=[DataRequired(),
                            EqualTo('password')])
    confirm_password = PasswordField('Confirm Password',
                                      validators=[DataRequired(),
                                                     EqualTo('password')])
    submit = SubmitField('Sign up')

class LoginForm(FlaskForm):

    email = StringField('Email',
                        validators=[DataRequired(), Email()])
    password = PasswordField('Password', validators=[DataRequired(),
                            EqualTo('password')])
    remember = BooleanField('Remember Me')
    submit = SubmitField('Login')

models.py

from datetime import datetime
from __main__ import db


class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(20), unique=True, nullable= False)
    email = db.Column(db.String(120), unique=True, nullable=False)
    image_file = db.Column(db.String(20), unique=False, nullable=False, default='default.jpg')
    password = db.Column(db.String(60), nullable=False)
    posts = db.relationship('Post', backref='author', lazy=True )

    def __repr__(self):
        return f"User('{self.username}', '{self.email}', '{self.image_file}')"

    def __init__(self, username, email, password):
        self.username = username
        self.email = email
        self.password = password


class Post(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    date_posted = db.Column(db.DateTime, nullable=False, default=datetime.utcnow)
    content = db.Column(db.Text, nullable=False)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

    def __repr__(self):
        return f"Post('{self.title }','{self.date_posted}')"

看起来你需要在 settings.json 文件中添加这个：

  "terminal.integrated.env.windows": {
    "PYTHONPATH": "${workspaceFolder};"
  },

在 Pycharm 中默认添加：Add content roots to PYTHONPATH。您可以在 PyCharm 中点击Edit Configurations 查找。
