The worker for a Google Cloud Platform task cannot find the logging library

Question

I have created a simple task based on the Google Cloud Platform "update counter" push task example . All I want to do is log that it has been invoked to the Stackdriver logs.

from google.cloud import logging
logging_client = logging.Client()
log_name = 'service-log'
logger = logging_client.logger(log_name)

import webapp2

class UpdateCounterHandler(webapp2.RequestHandler):
    def post(self):
        amount = int(self.request.get('amount'))
        logger.log_text('Service startup task done.')


app = webapp2.WSGIApplication([
    ('/update_counter', UpdateCounterHandler)
], debug=True)

After deploying this and invoking it, there is an error. In the logs online it says:

from google.cloud import logging
ImportError: No module named cloud

This isn't a local version, but one that I've deployed. It's hard for me to believe that I have to actually install python libraries into the production runtime. (I can't even imagine that I can.)

Answer 1

As the root readme states:

Many samples require extra libraries to be installed. If there is a requirements.txt , you will need to install the dependencies with pip .

Try adding the library as explained here .

Answer 2

When using logging from the Python standard library in App Engine, the logs also end up in Stackdriver. So you could use import logging instead of from google.cloud import logging .

When you are specifically interested in using the google.cloud.logging library, then it needs to be installed to a project folder ./lib as referred by Tudormi: here
