我在自学Flask，在看《FlaskWeb开发：基于Python的Web应用开发实战》这本书，目前已经做到了用户注册这一块，卡在了用户注册完需要邮箱确认才可以更完整的编辑信息，是不是用Venv模拟环境下是不能发送邮件的？这一点很迷惑，希望有前辈能指点一下。

界面图片如下：

代码是从官方github克隆的。

from ..email import send_email @auth.route('/register', methods = ['GET', 'POST']) def register(): form = RegistrationForm() if form.validate_on_submit(): # ... db.session.add(user) db.session.commit() token = user.generate_confirmation_token() send_email(user.email, 'Confirm Your Account', 'auth/email/confirm', user=user, token=token) flash('A confirmation email has been sent to you by email.') return redirect(url_for('main.index')) return render_template('auth/register.html', form=form)
