jinja2.exceptions.TemplateNotFound

[Felipe Perry]

Hello, I've come this -and a large traceback-, with all dependencies installed ...

 thank you very much

jinja2.exceptions.TemplateNotFound
TemplateNotFound: layout.html

[Friedrich Lindenberg]

Hi Felipe, 

sorry for the extreme lag in getting back to you. The problem may be a result of a bug in the version of grano-ui that is currently available on PyPI (i.e. via ‘pip’). Perhaps as a workaround you could try to install `grano-ui` via git, i.e. do: 

git clone https://github.com/granoproject/grano-ui.git 

cd grano-ui

python setup.py develop 

That should solve the problem. If it doesn’t, please let me know! 

- Friedrich

Oh, the documentation (and what I have sent you) is missing another step: downloading bower dependencies (i.e. the JavaScript bits). If you can, just run this in your grano-ui directory:

sudo npm install -g bower
bower install

This will download JS and CSS dependencies for the frontend.

I’ll add it to the documents ASAP!
