Guys,
help me please to fix my problem.
Environment:
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
please check following thread How to install 3rd party libraries or sdks into the application - #2 by makarand_b.
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 
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):

@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:
from colorama import init <--- this causes import error
but this works:
colorama = frappe.get_module("colorama") colorama.init()
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
