用Ros2 Foxy窗口执行colcon生成问题

Question

当我试图构建我的工作区时(我在windows中使用Ros2 Foxy )，我得到了以下跟踪：

    --- stderr: dynamixel_sdk_custom_interfaces
Traceback (most recent call last):
  File "<string>", line 1, in <module>

  CMakeLists.txt:31 (rosidl_generate_interfaces)

有人知道怎么解决吗？

我注意到这一点：

WinError 193

它看起来您的python运行时版本与Numpy不匹配(CPU arch不同吗？)也许您已经安装了Anacoda，并且它重写了默认的python路径。

您可以尝试检查您的python路径。
