Bolt can't run elm lang and ruby on rails

[dhelbegor]

Describe the bug

Currently I`m trying to create apps using elm lang and ruby on rails but Bolt always fails to install them. there is a way to install it manually or do we need to implement a feature to solve this issue?

In terms of programming languages what limitations do we have?

for rails the error bellow:
~/project ❯ rails server jsh: command not found: rails

and this one is for elm lang
~/project ❯ elm make Main.elm --output=elm.js jsh: command not found: elm

Steps to reproduce

type: create a simple todo app using elm lang.

1 - the prompt will create the code

2 - the bolt will try to run it but will fail

Expected behavior

run the application built in the target language, elm or rails directly in bolt.

Hi @dhelbegor,
unfortunately the webcontainers only support NodeJS based applications so far. As they come from stackblitz, we cannot change anything on this.
There were some more discussions about this and also changing to another solution in the community:
