Dear Wang, thanks for your reply,

I believe Ubuntu is delivering patch 6 (based on what I see from ROS2 website).

I’ll try this 0.10.3 and i’ll give you feedback. I understand that ROS2 has a release every 6 months, but again, people try to stick to the long EOL release (unfortunately I named LTS), to manage migration and support of products. I hope you can help with this issue as Dashing will be supported longer then successor and your project could be interesting for exposing ROS data over the web.

Let me know if I might help someone to reduce bugfix time although I am nothing good at javascript eheheg

Thanks for @wayneparrott https://github.com/wayneparrott’s explanation and I want to share my thoughts about this problem.

• Which version should I use?

Usually, each release of rclnodejs targets on a (patch) release of ROS2. There are 7 releases of Dashing totally, including 1 main release and 6 patch release (the latest version is patch release 6 https://github.com/ros2/ros2/releases/tag/release-dashing-20200319). Meanwhile, we have 4 releases of rclnodejs accordingly, please see below: ROS 2.0 release NPM version Dashing Diademata Patch Release 4 https://github.com/ros2/ros2/releases/tag/release-dashing-20191018 0.10.3 https://github.com/RobotWebTools/rclnodejs/releases/tag/0.10.3 Dashing Diademata Patch Release 3 https://github.com/ros2/ros2/releases/tag/release-dashing-20190910 0.10.2 https://github.com/RobotWebTools/rclnodejs/releases/tag/0.10.2 Dashing Diademata Patch Release 2 https://github.com/ros2/ros2/releases/tag/release-dashing-20190806 0.10.1 https://github.com/RobotWebTools/rclnodejs/releases/tag/0.10.1 Dashing Diademata Patch Release 1 https://github.com/ros2/ros2/releases/tag/release-dashing-20190614 0.10.0 https://www.npmjs.com/package/rclnodejs/v/0.10.0

We cannot ensure that rclnodejs runs correctly on patch relase 5&6, maybe you could run npm i rclnodejs@0.10.3 to have a try on these two releases:

But if you installed Dashing by Debian packages https://index.ros.org/doc/ros2/Installation/Dashing/Linux-Install-Debians/, you may not be aware of the exact release (I reckon it is patch release 6).

• About ROS2 LTS distro

Personally speaking, I don’t think there is a kind of LTS distro until now, you could check out all the releases here https://index.ros.org/doc/ros2/Releases/#releases, although EOL of Dashing is May 2021. The community publishes a new release every 6 months followed by several patch releases. That will be changed after Foxy https://index.ros.org/doc/ros2/Releases/Release-Foxy-Fitzroy/.

Currently, the develop branch of rclnodejs tracks to master of ROS2, so we can keep it compatible as soon as a stable release of ROS2 is published. As @wayneparrott https://github.com/wayneparrott said, you are encouraged to install Eloquent at the current stage, unless you have strong reasons to stay on a specific ROS2 release.

This is the error. Tnx for letting me hope 😃
