I found similliar issues:

Thanks for help.

Ubuntu 16.04.4 LTS
npm 3.10.10
yarn v1.5.1

It may help to say what the OS is and what versions of node and npm and yarn.

Thanks, i updated post.

On a Bionic instance here ,

ERPNext: v12.14.0
Frappe v12.12.0
npm 7.0.14
yarn 1.22.5
nodejs v15.3.0

I don’t know if upgrading will help, but worth a try?

Wow Thanks. Upgrading nodejs was solution:

I used commands:

sudo apt-get install -y nodejs
sudo apt install -y nodejs yarn

I though that nodejs is upgraded after running command:
bench setup requirements

Thank you very much
