ImportError: No module named 'MySQLdb' 使用 Flask 时出现问题

Question

我正在尝试使用 Flask 和 phpmyadmin 构建 CRUD web 服务器。 当我在 pycharm 终端中使用以下命令时出现问题

> from app import db
> db.create_all()

 Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Tariq\PycharmProjects\IPAM\venv\lib\site-packages\flask_sqlalchemy\__init__.py", line 1039, in create_all

我的 app.py 如下

from flask import Flask, render_template, request, redirect, url_for, flash
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.secret_key = "Secret Key"

# SqlAlchemy Database Configuration With Mysql
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:''@localhost/crud'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False

db = SQLAlchemy(app)


# Creating model table for our CRUD database
class Data(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(100))
    email = db.Column(db.String(100))
    phone = db.Column(db.String(100))

    def __init__(self, name, email, phone):
        self.name = name
        self.email = email
        self.phone = phone


# This is the index route where we are going to
# query on all our employee data
@app.route('/')
def Index():
    all_data = Data.query.all()

    return render_template("index.html", employees=all_data)


# this route is for inserting data to mysql database via html forms
@app.route('/insert', methods=['POST'])
def insert():
    if request.method == 'POST':
        name = request.form['name']
        email = request.form['email']
        phone = request.form['phone']

        my_data = Data(name, email, phone)
        db.session.add(my_data)
        db.session.commit()

        flash("Employee Inserted Successfully")

        return redirect(url_for('Index'))


# this is our update route where we are going to update our employee
@app.route('/update', methods=['GET', 'POST'])
def update():
    if request.method == 'POST':
        my_data = Data.query.get(request.form.get('id'))

        my_data.name = request.form['name']
        my_data.email = request.form['email']
        my_data.phone = request.form['phone']

        db.session.commit()
        flash("Employee Updated Successfully")

        return redirect(url_for('Index'))


# This route is for deleting our employee
@app.route('/delete/<id>/', methods=['GET', 'POST'])
def delete(id):
    my_data = Data.query.get(id)
    db.session.delete(my_data)
    db.session.commit()
    flash("Employee Deleted Successfully")

    return redirect(url_for('Index'))


if __name__ == "__main__":
    app.run(debug=True)

任何建议我如何解决它.. 我已经安装了 pymysql (pip install pymysql) 然后 (SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://.....' ) 仍然得到同样的错误

亲切的问候
