Error with AppEngineConfigException when trying to start app inventor

bcapuzzo · January 30, 2024, 4:17pm

I am trying to build and run app inventor on my local machine using the README instructions here. I set up vagrant and successfully built app inventor with 'ant', but when I try to start app inventor, I get the following error. Does anyone recognize this error or might know a solution? Thanks!

vagrant@ubuntu-bionic:/vagrant/appinventor$ start_appinventor

The vagrant system uses an old build of the App Engine SDK that is no longer compatible with the version needed by App Inventor for Google Cloud. Generally, I recommend against folks using the vagrant build if they are planning to do any serious work with the App Inventor sources since the you pay a significant performance penalty compiling the sources within the VM.

Wondering what is the recommended way to install and run a local version of App inventor for 10-20 students ?

May be the problem with Vagrant could be mentioned in app inventor source-github
