type object 'type' has no attribute '_TYPE_SUPPORT' This might be a ROS 1 message type but it should be a ROS 2 message type. Make sure to source your ROS 2 workspace after your ROS 1 workspace.

py编译时遇到的问题，请教一下该怎么解决没找到解决办法

import rclpy
from rclpy.node import Node
from std_msgs.msg import String


class Writenode(Node):
    def __init__(self,name):
        super().__init__(name)
        self.get_logger().info("大家好我是作家%s."%name)
        #发布者
        self.pub_thing = self.create_publisher(String,"yellow",10)
        # self.pub_thing.publish()发布函数
        #prama1: 周期 
        self.count = 0
        self.timer_period=5
        self.timer = self.create_timer(self.timers_period,self.time_cailback)

    def time_cailback(self):
        msg = String()
        msg.data="黄色小说嘿嘿，第%d"%self.count
        self.pub_thing.publish(msg)
        self.get_logger().info("内容为%s"%msg.data)
        self.count+=1

        

def main(args = None):
    rclpy.init(args = args)

    lu_node = Writenode("lu")
    
    rclpy.spin(lu_node)
    rclpy.shutdown()

报的错误

@2449154969 在 type object 'type' has no attribute '_TYPE_SUPPORT' This might be a ROS 1 message type but it should be a ROS 2 message type. Make sure to source your ROS 2 workspace after your ROS 1 workspace. 中说：

AttributeError: type object 'type' has no attribute '_TYPE_SUPPORT' This might be a ROS 1 message type but it should be a ROS 2 message type. Make sure to source your ROS 2 workspace after your ROS 1 workspace.

看提示是你ROS1的环境和ROS2的环境混了

@小鱼 source /opt/ros/foxy/setup.bash我现在环境只有这个emm把ros1的以经去掉了
