Problem executing colcon build with Ros2 Foxy windows

Question

I am getting the following tracebacks when I try to colcon build my workspace (I am using Ros2 Foxy in windows):

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

  CMakeLists.txt:31 (rosidl_generate_interfaces)

Does anyone know how to solve it?

Answer 1

I notice this:

WinError 193

It looks your python runtime version is not match Numpy (CPU arch different?). Maybe you had installed Anacoda and it overrides the default python path.

You could try to check your python path.
