Hi @taufanbudiman, thanks for your answer 
I think that i activate the virtual_env correctly and work as edxapp:
To install figures the first thing i do in the command line is this:
sudo su edxapp -s /bin/bash
cd /edx/app/edxapp
. edxapp_env
. venvs/edxapp/bin/activate
Then git clone the repo:
git clone -b build-0.3.9 GitHub - appsembler/figures: Reporting and data retrieval app for Open edX
And access the frontend folder:
cd frontend
I then type yarn or yarn build and that when i get the errors.
