Trying to build Foxy in Windows 10. After installing everything, I get a bunch of errors when running colcon:

*C:\dev\ros2_foxy>colcon build --merge-install*
[7.597s] **colcon.colcon_core.package_identification** ERROR ROS package 'share\action_tutorials_py' with build type 'ament_python' has no 'setup.py' file
[7.611s] **colcon.colcon_core.package_identification** ERROR ROS package 'share\ament_clang_format' with build type 'ament_python' has no 'setup.py' file
...

and many more

Actually the errors where happening with packages in the folder ros2_foxy\share where setup.py was not copied. But these packages are also in other folders under src, generating another error, so I removed the ones in the share folder. I do not know how they arrived to the share folder or if there is any reason to have them there, but, without share folder, colcon builds.

I had this same issue. I had downloaded the source from the website and unzipped it to C:\dev\ros2_foxy. But I should have started with a clean directory and run the following:

md \dev\ros2_foxy\src
cd \dev\ros2_foxy
curl -sk https://raw.githubusercontent.com/ros2/ros2/foxy/ros2.repos -o ros2.repos
vcs import src < ros2.repos
colcon build --merge-install
