试过删除build没用，anaconda卸载后编译成功，再开机文件就乱了，然后建了一模一样的工作空间，编译又不通过。实在不知道怎么改了

@1194100657 在 3.7.3.1 自定义接口实践编译报错中说：

anaconda卸载后编译成功，再开机文件就乱

目录有没有存在中文之类的，构建目录位置是否正确

@灵思皇后

@小鱼目录没有中文，文件位置，编译的文件夹也没错。之前的代码编译都没有问题。

@1194100657 在 3.7.3.1 自定义接口实践编译报错中说：

exist relative to the CMAKE_CURRENT_SOURCE_DIR
'/home/ljy/roscode/chap3/example_ros2_interfaces'

看这个错误，你试试把目录带 install
build 都删掉，一层层的看看，

@灵思皇后

@小鱼报错全文是这样的

@灵思皇后

@小鱼全删过不好使

@灵思皇后

@小鱼

/opt/ros/humble/share/rosidl_cmake/cmake/rosidl_generate_interfaces.cmake:93 是这样的

小鱼

@1194100657 有修改过bashrc吗，重新打开一个中断试试

目录结构错了，Moveobot.srv应该在srv下，你的这里是同级目录了，自然找不到报错。
