Question

我正在尝试通过flask_mail通过电子邮件发送pandas DataFrame：

from flask import Flask, redirect, render_template, request, url_for, jsonify, session
from flask_mail import Mail, Message
app.config['MAIL_SERVER'] = 'smtp.****.com'
app.config['MAIL_PORT'] = ***
app.config['MAIL_USE_TLS'] = True
app.config['MAIL_USERNAME'] = '****'
app.config['MAIL_PASSWORD'] = '***'
mail = Mail(app)

@app.route("/sent", methods=["GET", "POST"])
def sent():
    recipient = str(request.form["email"])
    df_*** = pd.read_msgpack(session['***'])
    df_client = pd.read_msgpack(session['client'])
    msg = Message("Thank you for your interest!",
                    sender="***@***.com",
                    recipients = [recipient])
    msg.html = df_client.to_html()
    msg_*** = Message("A new calculation was made by {{email}}",
                sender="***@***.com",
                recipients = ["***@***.com"])
    msg_***.html = df_***.to_html()
    return "Thank you for showing interest!"

但是，我继续遇到相同的错误：

2019-12-02 11:08:34,919: Error running WSGI application
2019-12-02 11:08:34,920: ModuleNotFoundError: No module named 'flask_mail'

但是，当我导入flask_mail时，我的代码中没有得到错误标签，或者当我尝试进行pip安装时，它似乎已经安装了：

已解决。我显然使用的是3.6，而不是3.7。因此pip3.6 install --user Flask-Mail解决了这个问题。

flask_mail似乎是在pythonanywhere中导入的，但是在运行时会得到错误代码：无模块命名
