isort failed on travis but works nice on my machine. Any ideas?

isort failed on travis but works nice on my machine. Any ideas?

Two ideas:

1. Make sure that the version of isort matches.
2. Make sure that you're installing exactly the same packages, as isort will report different things on where an import should be if the package is not installed.

[jacquerie]

It's probably 2., given that it's complaining about invenio_db, and you don't install it in the all extra (but you install it by choosing which DB backend to use, e.g. $ pip install -e .[all,sqlite3].)

[jma]

You are right: isort version matches, thus it is 2! But invenio-db is installed... I created a virtualenv from scratch and follows the travis steps and solved isort errors. I hope it will works!

[jma]

Seems ok.

[jma]

Any news?

I just noticed a question of which I happened to know the answer to, @david-caro is probably the person who should be looking at this.

[david-caro]

Looks good to me :), thanks for the PR!

[david-caro]

@jma Do you need this feature? I can do a release if that helps.

[jma]

@david-caro Yes, it is require for RERO DOC. Thanks for the merge.
