Bench --site <site> install-app erpnext failure

I have been trying to get erpnext installed on an AWS Ubuntu (18.04) instance.

This is a clean install onto a freshly updated Ubuntu with no other software installed. After the error message below I include my “script” that I am following for the install.

Here is the error I get after making a new site in bench and attempting to add the erpnext module:

Here is the Explore View. Lots of missing items here.

Seems your frappe and erpnext instances might be on separate (and incompatible) branches. Maybe there needs to be a validation for this.

If I do a simple

git clone
pip install -e ./bench
bench init frappe-bench

Which branch am I on? Master or Develop? Is there a bench command which will tell me?

cd frappe-bench
bench get-app erpnext

Which branch is erpnext on?
How do I force them to be on master (currently v11)?

If you go to apps/frappe and apps/erpnext, the command git status will tell you what branch you’re currently on.

OK - so the default is “upstream/develop”.

And I apparently have uncommitted files.$ git status
On branch develop
Your branch is up to date with 'upstream/develop'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)


nothing added to commit but untracked files present (use "git add" to track)

I’m not sure this is going well.

Hmm…the uncommitted files are odd. You could try git diff to see what has been changed.

Regardless, if you don’t have a site setup yet (and thus not much to risk), it should be easy enough to switch over to master and then force a clean refresh.

bench switch-to-branch master frappe erpnext
bench update --force

I think I’ll go back a few steps to avoid pulling the develop branch in the first place.

bench automatically tracks master, develop, and staging for both frappe and erpnext, so you’re pulling all three no matter which version you install. The only thing the switch-to-branch command does is change which snapshot is active in your file system.

If you’re doing the manual install (and it looks like you are), you’ll start with the develop branch by default, and if you want master you just switch branches. The “easy install” script, on the other hand, gives you an option to choose between the two.
