Module <module> not found

What it means

The build imports a module that is not a dependency.

The error happened while installing dependencies or building the project. The new version was not started, the current one keeps running.

Typical causes

• The install or build command exited with an error
• Out of memory or disk space
• The language or package manager version is not the one the project expects
