在运行fishbot仿真时按照鱼哥的文件加载，报以下错误，无法加载模型。

试过换源更新，没有作用。
换源时出现警告

求解决

@追逐我的明天在用launch文件运行gazebo时报错，找不到rclpy._rclpy_pybind11 中说：

/opt/ros/humble/lib/gazebo_ros/spawn_entity.py -entity fishbot -file /home/gh/d2lros2/fishbot_ws/install/fishbot_description/share/fishbot_description/urdf/fishbot_gazebo.urdf --ros-args

手动加载模型到gazebo可以吗

追逐我的明天

@小鱼可以，只有用launch文件不行

看看这个路径有没有文件

追逐我的明天

@小鱼没有这个名字，改了个名还是不行

小鱼

@追逐我的明天所以有这个文件吗，你的该setup.py 进行 install文件哈

追逐我的明天

@小鱼没有我把src下模型文件改成了这个名字

小鱼

@追逐我的明天要确保报错的那个文件存在

追逐我的明天

@小鱼现在文件存在但仍然报错替代文字

来解决这个错误吧，你有用conda吗

追逐我的明天

@小鱼用了这个文件我按目录是找不到的

追逐我的明天

@小鱼 conda deactivate退出conda环境就解决了笑死
