HTML templating using Jinja2 No module named your app

jinja2, python

Solution

I don't know much about Environments and Loaders, but this is what I use:

jinja_environment = jinja2.Environment(
    loader=jinja2.FileSystemLoader('%s/templates/' % os.path.dirname(__file__))
)

Problem

I am trying to create a html template in python using Jinja2. I have a templates folder with my 'template.html' but I don't know how to deal with environments or package loaders. I installed Jinja2. These my simple codes ``` from jinja2 import Environment, PackageLoader env = Environment(loader=PackageLoader('ap', 'templates')) template = env.get_template('template.html') print template.render(title='hello') ``` I get this error: ``` File "a.py", line 3, in <module> env = Environment(loader=PackageLoader('ap', 'templates')) File "/usr/local/lib/python2.7/dist-packages/Jinja2-2.7-py2.7.egg/jinja2/loaders.py", line 214, in __init__ provider = get_provider(package_name) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 213, in get_provider __import__(moduleOrReq) ImportError: No module named ap ``` This my folders ``` ap/ __init__.py a.py templates/ template.html ``` Where am I wrong ? Why I get this error "No module named your application"
