问题描述
安装ros（旋律版）后，我一步一步地执行了以下步骤。
$ mkdir -p catkin_ws/src
$ cd catkin_ws/src
$ catkin_init_workspace
$ cd ..
$ catkin_make
然后出现这样的错误
CMake Error at CMakeLists.txt:1:
Parse error. Expected a command name,got unquoted argument with text
"/opt/ros/melodic/share/catkin/cmake/toplevel.cmake".
-- Configuring incomplete,errors occurred!

Makefile:320: recipe for target 'cmake_check_build_system' Failed
make: *** [cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" Failed
我发现'home / catkin_ws / src'文件夹中的CMakeLists.txt文件显然存在，但仅包含此消息。
/opt/ros/melodic/share/catkin/cmake/toplevel.cmake
我该如何解决这个问题？
解决方法
看起来您正在尝试编译已编译的项目。因此，请删除“home/catkin_ws/src”中的 CMakeLists.txt 文件，或者出于安全考虑将其移动到另一个文件夹，然后在终端上运行 catkin_make 命令。
