Question

我正在尝试为ROS软件包中的示例教程编译构建文件。以下显示在终端机中，

Errors     << catkin_tools_prebuild:cmake /home/comet/mybot_ws/logs/catkin_tools_prebuild/build.cmake.009.log
CMake Error at /opt/ros/kinetic/share/catkin/cmake/safe_execute_process.cmake:11 (message):

  /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:20 (include)
  CMakeLists.txt:4 (find_package)

似乎它正在尝试访问anaconda3文件夹中的python编译器，但最近将其卸载了。有什么想法可以修改文件，使其指向/ usr / bin python吗？任何想法表示赞赏。非常感谢你！

Answer 1

最近才解决它，我在catkin clean之前执行了catkin build。

Answer 2

所以您的环境受到污染的可能性有两种

通过指向您的蟒蛇位置，您的PATH变量仍然受到污染。请参阅this question以获取参考并删除anaconda条目。不要忘记打开新终端以应用更改
在获取anaconda环境的同时，您已经创建了本地catkin工作区。因此，您只需要删除当前工作区中的build和devel，然后从头开始重建所有内容即可。

一个接一个地处理两个步骤应该可以解决问题。

catkin版本无法编译
