Python & Flask 错误使用 Flask-MySQL | 未找到模块错误：没有名为“flask_mysqldb”的模块

Question

In my system, I installed the flask_mysqldb , however when I run the app.py file it shows an error like nomodule named flask_mysqldb .

I tried another way of downloading mysqlclient and installed it, but the same error occurs.

Error

The error is  line 2, in <module>
    from flask_mysqldb import MySQL
ModuleNotFoundError: No module named 'flask_mysqldb'

I would appreciate a solution, thanks.

Answer 1

After some research I can suggest you to do the following:

from flask import Flask, render_template, json, request
from flaskext.mysql import MySQL

mysql = MySQL()
mysql.init_app(app)

Another way to connect and define your credentials to MYSQL would be:

from flaskext.mysql import MySQL
mysql = MySQL()
mysql.init_app(app)

Finally:

from flask import Flask, render_template
from flaskext.mysql import MySQL

mysql = MySQL()
app = Flask(__name__)
mysql.init_app(app)

@app.route('/')
def index():

    return render_template('index.html')


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