Hey @etaylork, is this an old app? I noticed that you are not using workspaces, which were introduced more than 1 year ago for new projects.

When not using workspaces in an app project, the CLI is forced to install dependencies for each extension independently, which in this case is failing by not finding git.

Three possible solutions:

• Easiest one: Run app build with the flag --skip-dependencies-installation
• Root cause: the error seems to indicate that you don't have git in your system, can this be the issue?
• Migrate your app to use workspaces. This might depend on your app, here is the doc for yarn workspaces. This migration would involve creating package.json files for your extensions either manually or regenerating them via app generate extension.
