Hi @seghier ,

It looks like your OpenStudio CLI is hitting some encoding error. Do any of the suggestions here help?

Do you get the same error when you run the command in the following format?

Hi @chris
In Ruby folder installation i fix the error with encoding but it look that openstudio use another ruby folder where the problem still exist, i search and read the topic you share but no solution yet

Thank you for posting the solution to this, @seghier . I am sure that you have helped a lot of people who might experience this issue and may find this post. I’ll see if I can add a better error message to the plugin when this encoding error arises.

FYI, I just added a better error message for this case:

Hopefully, this increases the chances of people changing their language settings when they encounter this issue.

Thank you , this will of course help people.
Another thing after some tests i found that ruby 32bits and ruby 3.0 64bits don’t work with Openstudio.
The version 2.7.4.1 64bits work better, but maybe other people don’t have a problem with this.

I try to update lbt-recipes, i set python from ladybug folder as interpreter but i got this error

pip install -U lbt-recipes
Fatal error in launcher: Unable to create process using '"c:\users\mingo\appdata\local\programs\python\python37\python.exe" 
"C:\Users\user\ladybug_tools\python\Scripts\pip.exe" install -U lbt-recipes': The system cannot find the file specified.

In my laptop there is no user called mingo

Hi @seghier ,
I don’t know how exactly you were able to get that error but you should just be able to use the LB Versioner to update your installation to the latest development version. That component will automatically call pip under the hood to update all of your core libraries (including lbt-recipes).
