Hello @builder,
You are probably missing this step:
Checkout dependencies - Appinventor Sources

Checkout dependencies
App Inventor uses Blockly, the web-based visual programming editor from Google, as a core part of its editor. Blockly core is made available to App Inventor as a git submodule. The first time after forking or cloning the repository, you will need to perform the following commands:
$ git submodule update --init
