I found the solution here on the qt forums. My problem originated with setting the environment variables to get anaconda working. QTPLUGINPATH=c:Anaconda3Libraryplugins But by setting this it breaks everything else. So for now I've just gotten rid of the path variable. To check if you have the env variable set. Press windows key + R. @jrmmuller said in 'could not find or load the Qt platform plugin 'windows' in '. If you could help me with the steps. Open cmd and type echo%QTPLUGINPATH% if it's not empty then delete it (just google: delete environmental variable windows #, where # is your windows version). Open cmd and type echo%PATH% and press enter. You'll see a list separated by; of folder paths.

I have installed ROS2 Eloquent from the pre-built binary package on Windows 10 v1809. Easy- webprint ex mac download windows 10. I followed the guide https://index.ros.org/doc/ros2/Instal..

The Talker/Listener example works, however when using:

the program yields 2 warnings:

Trying out the tutorial https://index.ros.org/doc/ros2/Tutori.. and using the turtlesim command:

Found a thread with the same problem, but this solution seems to fix the problem when installing from source and hence installing QT, which is not needed for the binary install? https://answers.ros.org/question/3392..

Finally, trying the 'rqt' command from the same tutorial yields:

I have extra checked the PATH variables from the guide and also added 'C:Python37Libsite-packagesPyQt5Qtpluginsplatforms', but no success.

Any solution to this? Do I need to install QT even though it's not in the guide? Thankful for answers./M

I had to install QT to get it to work for me.

Thanks billy, I was able to run turtlesim by doing that. However, when trying to run the commands where visuals are needed, I think the original problem remains. For example rqt, rqt_graph, rqt_console. Any succes with those?

Oh yes. Same issue for me. Installing QT fixed issue with the turtlebot simulation, but I get same errors trying to run RQT.

Hi marreb and billy, I'm having the same problems. Were you able to find a solution to this?

I fixed RQT_graph somewhat by:

Install windows package from: https://graphviz.gitlab.io/_pages/Dow..
Install python graphviz package
Add C:Program Files (x86)Graphviz2.38bin to User path 4 Add C:Program Files (x86)Graphviz2.38bindot.exe to System Path

However, rqt_graph works poorly and crashes uncontrollably. But you get to visualize your nodes/topics for a limited time =)

Hi guys, have you ever solved this issue about the RosPluginProvider in RQT?

Hi @songyuc, I switched installation method to http://wiki.ros.org/Installation/Windows.

Some fixes to that install can be seen here: https://answers.ros.org/question/3478..

However, you can run rqt with with binary install if you do the fixes in earlier comments, ignore the RosPluginProvider errors.

Hi @marreb, I think this issue may be relevant to the Graphviz, and I installed the Graphviz based on your previous solution. Then the errors about the Graphviz disappear.
