Datapusher: 500 Server Error

[Thekings2468]

Hello, so it's my first time using CKAN and I followed the CKAN doc (package installation) to install it on a VPS over SSH (Ubuntu 14.04 LTS). I did all the steps but when I was to use datapusher in the CKAN site it gave me an error
Upload error: An Error occurred while sending the job: 500 Server Error: Internal Server Error for url: http://127.0.0.1:8800/job
I search for a solution but I can't find anyone with the same problem as mine. DataStore API worked so I think the problem resides in Datapusher itself.
Another thing is that curl 0.0.0.0:8800 gives me this error aswell (500 Internal Error in html).

I have followed the steps here as the error is the same, but it didn't work (even by restarting apache2 and nginx).

@Thekings2468, how did you solve this problem?

@Thekings2468, @krzpam,

Hi, I'm Francesco Venuto, I work for Corvallis SPA at Caltagirone, Italy.
During one of the many installations of CKAN I had the same problem.
The error:

---

Target WSGI script '/etc/ckan/datapusher.wsgi' can not be loaded as Python module.
Exception occurred processing WSGI script '/etc/ckan/datapusher.wsgi'.
Traceback (most recent call last):
File "/etc/ckan/datapusher.wsgi", line 8, in
import ckanserviceprovider.web as web
File "/usr/lib/ckan/datapusher/lib/python2.7/site-packages/ckanserviceprovider/web.py", line 13, in <mod $
import flask.ext.login as flogin
ImportError: No module named ext.login

---

You have to check if the modules Flask and Flask_login are installed and if necessary install them:

pip uninstall flask (if is installed in other version)
pip install flask == 0.12

pip install flask-login

then you have to check the file /ckanserviceprovider/web.py (possible path):
/usr/lib/ckan/datapusher/lib/python2.7/site-packages/ckanserviceprovider/web.py

and replace: import flask.ext.login as flogin

with: import flask_login as flogin

because flask.ext.login is obsolete

finally restart datastore and ckan

sudo a2ensite datapusher
sudo service apache2 restart

I hope you have been helpful
Greetings and best wishes

It works! Thank you :)

[Thekings2468]

I got through the steps @francescoVenuto suggested while googling, but you have to enter datapusher's own virtualenv and execute the pip commands for it to work.

Thank you very much Franchesco!! I have been crazy wontted a solution.

Hi I running CKAN 2.8.2 and flask 0.12.4 and am getting the same error. Any ideas of what else could cause the issue.

[davidread]

@JudyMor have you considered switching to ckanext-xloader? datapusher is not being maintained afaict.
