Question

I have installed lxml yet.

It works fine in IDLE.

But when I start an basic app described below with dev_appserver.py ,server returns error “No module named lxml”.

import webapp2,lxml

class MainPage(webapp2.RequestHandler):
    def get(self):
        self.response.out.write("test")
app = webapp2.WSGIApplication([("/(.*)", MainPage)],debug=True)

How can I resolve this??

Thanks!!

Assumingly you’re using Python 2.7 runtime. This runtime provides a fine way for configuring libraries.

Please add libraries section in your app.yaml as follows:

libraries:
- name: lxml
  version: latest
