webapp2 Import Error

[Scott Lewis]

Hi,

I'm new to web development, and particularly python development, so
please forgive any obvious mistakes that I've made. Any help would be
greatly appreciated.

I'm trying to use webapp-improved (http://code.google.com/p/webapp-
improved/) on my local Windows Vista system. The results I'm getting
are:

Traceback (most recent call last):
File "C:\Program Files (x86)\Google\google_appengine\google\appengine
\tools\dev_appserver.py", line 3211, in _HandleRequest
self._Dispatch(dispatcher, self.rfile, outfile, env_dict)
File "C:\Program Files (x86)\Google\google_appengine\google\appengine
\tools\dev_appserver.py", line 3154, in _Dispatch

exec module_code in script_module.__dict__
File "C:\Users\slewis\Desktop\helloworld\helloworld.py", line 1, in
<module>
import webapp2 as webapp
ImportError: No module named webapp2

My python file looks like:

import webapp2 as webapp

class HelloWorldHandler(webapp.RequestHandler):
def get(self):
self.response.out.write('Hello, World!')

app = webapp.WSGIApplication([
(r'/', HelloWorldHandler),
], debug=True)

def main():
app.run()

if __name__ == '__main__':
main()

I started development using python 2.7 and got this issue, then from
reading on this group that 2.5 was preferable, I switched to that, but
nothing has changed. I was able to run the google app engine tutorial
without errors, so I believe something is wrong with how I installed
webapp2. (I uncompressed it in a separate directory, then navigated
there in the command line and executed 'python setup.py install' and
there were no errors on the install.)

Again, any help would be greatly appreciated! Thank you.

Hi Scot,
Did you python setup install from the map where you unpacked webapp2?
ImportError: No module named webapp2, seems python can't find webapp2

Or you add webapp2 into the EXTRA_PATHS variable in the dev_appserver.py file.
