ros2 source install on windows

I am trying to install ros2 from source on windows and am having some trouble; I followed the instructions here and then ran the following to build from master

> cd \dev\ros2_master

> curl -sk -o ros2.repos

> vcs import src < ros2.repos

> colcon build --merge-install --packages-up-to rosbag2

Currently, I just want to build until rosbag2. However, running the build command throws the following Cmake warnings for a lot of packages

CMake Warning at C:/dev/ros2_master/install/share/ament_cmake_pytest/cmake/ament_add_pytest_test.cmake:77 (message): The Python module 'pytest' was not found, pytests can not be run (e.g. on Ubuntu/Debian install the package 'python3-pytest') Call Stack (most recent call first): CMakeLists.txt:256 (ament_add_pytest_test)

After build:

Summary: 128 packages finished [6min 17s] 1 package failed: rosbag2_storage_default_plugins 8 packages had stderr output: rclpy rmw_connext_cpp rmw_connext_shared_cpp rosidl_adapter rosidl_generator_py rosidl_parser rosidl_typesupport_connext_c rosidl_typesupport_connext_cpp 7 packages not processed

Not really sure why the pytest module cannot be found.

I then created another workspace with code from foxy and was able to build that successfully. Why might this be happening in master?

I just had this same issue. In my case I fixed it by doing python -m pip install pytest==6.0.0
