Answer 1

I don't know the process involved with packaging but I figure since Jinja2 is written in Python, the process would be the same as packaging any other application in Python.

Here are a few links that may be useful to you:

• The Hitchhiker's Guide to Python (great resource): Packaging Explained
• Alternatives to Packaging: freeze your application
• Python Packaging User Guide (probably the most useful to you)

I hope this helps.

Answer 2

Maybe an issue is in PYTHONPATH . According to Python documantation https://docs.python.org/2.7/tutorial/modules.html#the-module-search-path it searches for modules in :

• the directory containing the input script (or the current directory).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• the installation-dependent default.

You can add some code to your application - printing sys.path variable to make sure your applcation's path is also there.

import sys
from jinja2 import Environment, PackageLoader # no prob, jinja2 correctly installed using pip
print sys.path # printing your sys.path
env = Environment(loader=PackageLoader('mypkg', 'template')) # causes server error

If it's not You can add by

sys.path.append(path_to_your_application) 

Answer 3

I've discovered a WORKAROUND, here. In this usage, the template is not part of a module or package; it is loaded directly from the file system. File system:

./index.py
./template.html

index.py:

#!/usr/bin/python
import jinja2

templateLoader = jinja2.FileSystemLoader( searchpath="." )
templateEnv = jinja2.Environment( loader=templateLoader )
TEMPLATE_FILE = "template.html"
template = templateEnv.get_template( TEMPLATE_FILE )
outputText = template.render( ) # this is where to put args to the template renderer

print ("Content-type: text/html\r\n\r\n")
print(outputText)
