npm run build not working: missing script: build

[vcjob]

How to reproduce the problem
Follow the install guide from github README.

Install from source
I want to remember you that this is the hardest setup way. You have to install Python/Node.js and type many commands.
Install Python
Install Node.js
Get the source code of doccano: git clone https://github.com/chakki-works/doccano.git
Move to doccano directory: cd doccano
Create environment for doccano: virtualenv venv
Activate environment: source venv/bin/activate
Install required packages: pip install -r requirements.txt
Move server directory: cd app/server
Build frontend library: npm install
Build frontend source code: npm run build
Back to server directory: cd ../
Initialize doccano: python manage.py migrate
Create user: python manage.py createsuperuser
Run doccano: python manage.py runserver
Stop doccano: Ctrl+C
Re-Launch doccano: python manage.py runserver (Confirm you are at app/server directory and environment is active).

Here is where I've got into trouble:
Move server directory: cd app/server
Build frontend library: npm install
Build frontend source code: npm run build

So, I do npm install and get:
npm WARN doccano No repository field.
npm WARN doccano No license field.

After I do npm run build:
npm ERR! missing script: build

And here's what the log has:

As the installation guide mentions the frontend, I went in doccano/frontend and did npm install; npm run build there, and it went well. Anyway, when I try to open the main doccano server page, I get the following:

Thank you for the help!

Installation instruction was based on before ver 1.0. We fixed it and please execute npm build at frontend directory.

Thank you. I did that, it didnt fix it though. Webpack-stats.json is still missing.
Anyway, I managed to use docker, so it's fine.
