Zyte Support Center

Hi,

I've been following https://support.scrapinghub.com/support/solutions/articles/22000200400-deploying-python-dependencies-for-your-projects-in-scrapy-cloud as a guide to include my dependencies in the requirements.txt file, but I'm having some issues.

I'm trying to use urllib.parse to analyse and clean up some URLs. First, I added the module urllib3 to my requirements.txt file as follows:

urllib3==1.22

When I try to deploy the project to Scrapinghub, I see the following error: 

ImportError: No module named parse
{"message": "shub-image-info exit code: 1", "details": null, "error": "image_info_error"}

{"message": "Internal error", "status": "error"}
Deploy log location: /var/folders/sy/5lq7m7v523v7wqkgymgbs8sm0000gn/T/shub_deploy_f9uckshv.log
Error: Deploy failed: b'{"message": "Internal error", "status": "error"}'

Then, I tried to generate the requirements.txt using pip freeze > requirements.txt, just to be sure that I was doing everything the right way. Now I get the following error while trying to deploy the project to Scrapinghub:

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-t95gfR/project/

{"message": "The command '/bin/sh -c sudo -u nobody -E PYTHONUSERBASE=$PYTHONUSERBASE     pip install --user --no-cache-dir -r /app/requirements.txt' returned a non-zero code: 1", "details": {"message": "The command '/bin/sh -c sudo -u nobody -E PYTHONUSERBASE=$PYTHONUSERBASE     pip install --user --no-cache-dir -r /app/requirements.txt' returned a non-zero code: 1", "code": 1}, "error": "requirements_error"}

{"message": "Requirements error", "status": "error"}
Deploy log location: /var/folders/sy/5lq7m7v523v7wqkgymgbs8sm0000gn/T/shub_deploy_z25sl9b6.log
Error: Deploy failed: b'{"message": "Requirements error", "status": "error"}'

May be this is a stupid question, but... what should I put on my requirements.txt to import urllib.parse? :_)

Thanks!!

Thanks for your reply :).

Here are the contents of my requirements.txt, generated using pip freeze: 

apiclient==1.0.3
attrs==16.3.0
certifi==2017.7.27.1
cffi==1.9.1
chardet==3.0.4
click==6.7
constantly==15.1.0
cryptography==1.6
cssselect==1.0.0
docker-py==1.10.6
docker-pycreds==0.2.1
fake-useragent==0.1.7
google-api-python-client==1.6.1
httplib2==0.9.2

idna==2.6

project==1.0
pycparser==2.17
PyDispatcher==2.0.5
pyOpenSSL==16.2.0
python-dateutil==2.6.0
pytz==2016.10
PyYAML==3.12

simplejson==3.10.0
six==1.10.0
tqdm==4.15.0
treq==17.3.1
Twisted==16.6.0
uritemplate==3.0.0
urllib3==1.22

 And these are the contents from my scrapinghub.yum file:

project: 270487
requirements:
  file: ./requirements.txt

The parse module is included in urllib, so I guess it is enough to add it to the requirements.txt.

Thanks!!

Any ideas about this? :)

Thanks!

Nop, sorry @thriveni, it wasn't that. I have removed project from requiremens.txt, but I still see the same error with urllib.parse when deploying to Scrapinghub:

ImportError: No module named parse
{"message": "shub-image-info exit code: 1", "details": null, "error": "image_info_error"}

I've just found the problem, and it is kind of stupid and a newbie one... I was having issues with the Python version :_).

Just changed my imports to:

try:
    from urllib.parse import urlparse, parse_qs, urlencode
except ImportError:
    from urlparse import urlparse, parse_qs
    from urllib import urlencode

Issue solved. Sorry for all the inconveniences, thanks for the help!!
