Can you try with “What to do if I have Python-related problems during the build of custom messages?" question in https://robostack.github.io/FAQ.html ? |

Feel free to reopen if it’s still an issue |

Thanks for the quick update, but still encountering the same error. |
Are you encountering the same error of the original post or the new error you are reporting? |
|
@traversaro I'm encountering the same error |
|
You are installing packages from robostack-humble, can you follow the instructions on the website and use the robostack-staging channel? |
|
@traversaro I have used this https://robostack.github.io/GettingStarted.html as ref for installing. |
Those instructions refer to robostack-staging channel, that is not the one reported in mamba list. |
|
I’m quite certain that the description in the FAQ fixes this - please follow the instructions carefully. |
