No module named 'MySQLdb'，但无法pip安装（并且这不是pip的问题）

当我尝试使用我的Flask应用程序进行POST数据时，出现了错误。\n这是我的SQLAlchemy类，有3个字段和相应的模式类：\n

class Plant(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(100))
    dur = db.Column(db.Integer)
    def __init__(self, name, dur):
        self.name = name
        self.dur = dur
class PlantSchema(ma.SQLAlchemySchema):
    class Meta:
        model = Plant

\n这是在app.py中的POST请求，以便将植物模型添加到我的数据库中：\n

plant_schema = PlantSchema()
@app.route('/plants', methods=['POST'])
def add_plant():
    name = request.json.get('name', '')
    dur = request.json.get('dur', '')
    plant = Plant(name=name, dur=dur)
    db.session.add(plant)
    db.session.commit()
    return plant_schema.jsonify(plant)

\n不幸的是，当我在Postman中进行POST请求时，我得到了以下错误：\n

    ...

\n当我尝试pip install mysqlclient（这是推荐的解决方法）时，我得到了以下错误：\n

\n如果问题不是由pip引起的，我不确定还有什么其他尝试的方法？
