Build web app in Ubuntu

[LSarribouette]

Hi all,

I am new to SDEverywhere and I am having trouble initialising everything. For now, the 'sir' example doesn't run properly.

I cloned the repository. I copied-pasted the sir folder outside of the repo.

I ran the command npm create @sdeverywhere@latest in the new folder and kept default answers.

After successful setup, I ran the command npm run dev and I got the error: Error: More than one string with key=graph_001_title.

Would you have an idea on how to fix this error?

Full error:

> project@1.0.0 dev
> sde dev

Hi @LSarribouette, thanks for submitting your question and including these helpful details. I moved the issue to a discussion board item in the Q&A section for now.

I believe the issue you are encountering is related to an open issue/improvement (#335). The issue in your case is that the sir example comes with a complete config folder (that already contains pre-populated graph and slider config files). So if you keep all the default responses to the questions asked by the "create" script, one of those will add a new graph (with ID "1") to the existing graphs.csv file, and another will add a new slider (with ID "1") to the existing inputs.csv file. The values in the "id" column in those csv files need to be unique, which is why you're seeing that error message.

As noted in #335, the "create" script shouldn't be asking those particular questions or adding to the existing graph/inputs config in the case where there's a pre-existing config folder. I would very much like to fix this when I have the time.

Until that is fixed, you can open the graphs.csv and inputs.csv files in your project and simply delete the lines that were added by the "create" script and leave the existing rows in place (or edit them to your liking). Or if you want to start over, you can go through the same "Quick Start" instructions as before, but skip (answer "no") to those two questions.

Let me know if this resolves your issue, or if you have further questions.

I'll also note that we have some (bare-bones/placeholder, sadly) instructions on the wiki that I hope to improve, because I know that getting started with the config files in SDEverywhere can be daunting to a newcomer. Feedback or contributions to the documentation are very much welcome.

Hi @chrispcampbell, thank you so much for your quick answer! It works perfectly now. Thank you also for putting my question in the right place, I wasn't sure where to put it.
