Both v10 upgrade to v11 and new v12 (develop) install running endless at building fresh packages step step


before this error, I run my erpnext on my ubuntu 16.04 without any problem.

anyone who can help?


I see the same when I want to upgrade to v12 just now following these steps

  1. bench update
  2. bench switch-to-branch version-12 erpnext frappe --upgrade
  3. bench update --patch
  4. bench setup requirements
  5. bench --site mysite.local migrate
  6. bench restart

on step #4 (setup requirements the process hangs on the building fresh packages stage every time I have tried to do this

yarn install v1.12.3
