ament-tools not found on Windows

[mfolsom3]

After following the ROS 2.0 install instructions, the examples ran fine.
However, I cannot build my own. Anytime I run ament, I get the below error.

pkg_resource:DistributionNotFound: Then ament-tools==0.0.0 distribution was not found and is required by the appliction

When I looked in the bin directory I did not see ament-tools

Can you please link to the installation instructions. That clarifies what steps you followed.

Please provide the exact command you ran as well as the full output. I sounds like you invoked ament which means that executable is available. There is no ament-tools executable in bin - it is named just ament.

What is the environment when you ran the command? Did you source the setup file before? Specifically what is the environment variable PYTHONPATH set to?

I followed this link
https://github.com/ros2/ros2/wiki/Windows-Install-Binary
Every thing worked as described.

Then I tried this tutorial (Develop your own package)
https://github.com/ros2/ros2/wiki/Ament-Tutorial

Below is the result of running the command:

c:\dev\ros2_VARRI_ws>ament build --cmake-args -DCMAKE_BUILD_TYPE=Debug

Did you source the setup file before? Specifically what is the environment variable PYTHONPATH set to?

[mfolsom3]

I did run setup.bat

There is no PYTHONPATH variable. However, my python directory is in my PATH variable

[dirk-thomas]

You need to call the setup.bat file to set the PYTHONPATH (or set it up manually, but there are other variables too). Without the Python code being on the PYTHONPATH it can't be found.

[mfolsom3]

OK I got this now. The setup.bat in the ros2 workspace everything runs fine. Just not in the overlay.
Thanks

If the problem is resolved for you can you please close the ticket.

If you still need help (not sure what "Just not in the overlay") please elaborate with more details. I assume you have tried to source the setup file of your overlay?
