Try ERPNext Buy Support Partners Foundation

Install requirements with bench problem (ImportError)

Guys,
help me please to fix my problem.

Environment:

  • bench 4.1.0
  • erpnext 7.0.53
  • frappe 7.0.39

I have added new library to requirements.txt

Why bench doesn’t not install my library during setup?

Not help me restart and some other stuff like:
bench restart
and
bench build
and
bench switch-to-master --upgrade
and
bench migrate
bench clear-cache
bench clear-website-cache

Always Import error

@Katerina_Romanchuk,

please check following thread How to install 3rd party libraries or sdks into the application.

Thanks, Makarand

Nothing helps me. This not resolve my problem:

try bench update --requirement
or
~frappe-bench/env/bin/pip install -r apps/your_app/requirements.txt


As example:

requirements.txt:

colorama


Setup everything on clean environment

bench get-app custom_application https://github.com/safo-bora/custom_application.git
bench --site erpnext.vm install-app custom_application
bench restart


And verify that my lib was installed:

frappe@erpnext:~/frappe-bench$ python
Python 2.7.6 (default, Jun 22 2015, 18:00:18)
[GCC 4.8.2] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
import colorama
Traceback (most recent call last):
File “”, line 1, in
ImportError: No module named colorama

ERROR :frowning:


I found interesting thing that it works in this way:

frappe@erpnext:~/frappe-bench$ bench shell
frappe@erpnext:~/frappe-bench/sites$ python
Python 2.7.6 (default, Jun 22 2015, 18:00:18)
[GCC 4.8.2] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.
import colorama
from colorama import init

OK! Works!


But why I see on my site error with import

how to fix this I don’t know:

Traceback (most recent call last):
File “/home/frappe/frappe-bench/apps/frappe/frappe/app.py”, line 55, in application

from colorama import init
ImportError: No module named colorama

@rmehta: may I ask you to help to investigate this issue on your end as well? This is going to be a real blocker on our end soon.

Thanks!

Hi Guys!

I was taking a look at this issue. Looks like frappe’s sandbox is broken for some third party modules. Here is are two example:

  1. Colorama module:
from colorama import init <--- this causes import error

but this works:

colorama = frappe.get_module("colorama")
colorama.init()
  1. with fedex module from: https://pypi.python.org/pypi/fedex/

Same issue:

from fedex.services.track_service import FedexTrackRequest <--- error module not found
from fedex.config import FedexConfig <--- error module not found

But this works:

fedex_track_service = frappe.get_module("fedex.services.track_service")
fedex_config = frappe.get_module("fedex.config")
FedexTrackRequest = fedex_track_service.FedexTrackRequest
FedexConfig = fedex_config.FedexConfig

Seems like the sandbox import path is broken to me on certain modules. I found similar reports for django’s sandbox and colorama.

Still not completely sure how to go about debugging this though.

To test the python console:

bench --site yoursite console

Bench python runs in a virtualenv, to use pip:

env/bin/pip install colorama
