Error when Upgrading to V13

ERPNext
1

Hi,

I’m trying to upgrade my ERPNext from V12 to V13.

When running below command:
bench switch-to-branch version-12 frappe erpnext --upgrade

I got this error:

Installing node dependencies for erpnext
$ yarn install
yarn install v1.22.10
[1/4] Resolving packages…

$ yarn run snyk-protect
yarn run v1.22.10

SyntaxError: invalid syntax

After that, whenever I run bench, it end up with error:

Traceback (most recent call last):
File “/usr/local/bin/bench”, line 11, in
sys.exit(cli())
File “/usr/local/lib/python2.7/dist-packages/bench/cli.py”, line 48, in cli
if sys.argv[1] in get_frappe_commands() + [“–site”, “–verbose”, “–force”, “–profile”]:
TypeError: unsupported operand type(s) for +: ‘NoneType’ and ‘list’

Any help is appreciated.

Use 13 instead of 12

bench switch-to-branch version-13 frappe erpnext --upgrade
3

Sorry, it was a typo. But yes, I’m using version-13. And those errors are the one I got.

Has bench update --patch been tried?

Now whenever I execute “bench”, it always response with an error

Upgrade your bench then check.

sudo -H pip3 install --upgrade pip
bench migrate-env python3

I’ve tried that. Same problem. Seems like I can’t run bench at all.
