Hi @Zia_Akbari ,

You can either find your version in remote branch:

$ git remote -r

or if you want to be more specific you can also find it in tags:

$ git tag -l

If you are checking out branch straight away, I guess its pretty simple to:

$ git checkout -b vYourVerion origin/vYourVersion
$ bench migrate

If you are fetching from the tag:

$ git checkout tags/<tag_name> -b <branch_name>

Hope this answers your question.

Let me know if this was not you were looking for.

Regards,

Parth

thanks @joshiparthin
I don’t have any tag when I run git tag -l there is nothing
but how do I use command checkout?
when I run git checkout -b v10.0.1 origin/v10.0.1 I get the bellow error

bench@mmerpdemo06:~/frappe-bench/apps/erpnext$ git checkout -b v10.0.1 origin/v10.0.1
fatal: 'origin/v10.0.1' is not a commit and a branch 'v10.0.1' cannot be created from it

did you try $git fetch before doing this ?

Try fetch and then see if it words. I could see the tags on my repo. I am not sure which IDE you are using, but my git plugin of my IDE also helps me to trace the tags.

Parth

Aren’t there going to be some conflicts in the resulting system?

You are attempting to install a lower version of the ERPNext App onto a more elevated version of the frappe bench.

It would seem to me that there might be some points of incompatibility between an old erpnext app and a very recent bench.

Is there a guaranteed backward compatibility in frappe framework? Will you always be able to install older apps that may have been based on older frappe framework (bench)?

Or… am I all wrong here?

Please advise.

@bkm, there’s a path, but it’s only forward looking.
Totally clean out the bench. You have to uninstall all the apps (including Frappe) and then a git pull with the a pattern like the one that Parth describes above, to which I’d add git fetch --unshallow is really useful. Otherwise this is the type of thing you want to be doing.

The success or failure depends on fetching and checking out exactly the version you want. Which is not really easy. And then you need to do it again for ERPNext.

Ahh… I did not realize one could uninstall frappe and still have anything left to work with.

This is something I need to experiment on and see if I can get a previous version to work.

Thanks for the extra clues! :+1:

When this happens, it is usually found that some python dependencies are missing or not installed properly by pip
it happens due to recent pip version upgrade is responsible for broken packages.

Find right pip version to install older versions of Frappe/ERPNext dependencies anything before v8 works good with pip version <= 9.0.1

some other findings:

This is an issue open at bench repo, causing pip upgrading to version 18 while init or install resulting in error while dealing with older versions of Frappe/ERPNext using Bench.
