下载教程7.导航示例代码后报错

[565517830]

下载代码后安装以来一直提示
克隆代码完成后，安装依赖一直提示：
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
fishbot_description: Cannot locate rosdep definition for [ament_python]
Continuing to install resolvable dependencies...
#All required rosdeps installed successfully

colcon build编译也报错，已经尝试重装过好几遍ros2环境，还未解决

@565517830 问题已解决，原因是因为把代码文件放在了含中文的路径下，换个不含中文路径的地方就可以了
