Cannot import webui2..module : invalid syntax line 92

[plat00n]

Hello,

I'm trying to install Shinken-2.4.3 on a Centos 6 which cannot access to the web. My python version is : Python 2.6.6

To start : I can't upgrade the os and I can't install python 2.7 (constraints)

Webui2 can't be started, I have this error message :

ERROR: [broker-master] Could not import bare 'module.py' from /var/lib/shinken/modules/webui2 : invalid syntax (connectionpool.py, line 92

Here is what i have installed :

sudo pip install Shinken-2.4.3.tar.gz
sudo pip install bottle-0.12.8.tar.gz
sudo pip install pymongo-3.7.2.tar.gz
sudo pip install chardet-3.0.4.tar.gz
sudo pip install idna-2.7.tar.gz
sudo pip install urllib3-1.24.tar.gz
sudo pip install certifi-2018.10.15.tar.gz
sudo pip install requests-2.20.0.tar.gz
sudo pip install passlib-1.7.1.tar.gz
sudo pip install six-1.11.0.tar.gz
sudo pip install arrow-0.12.1.tar.gz
sudo pip install python-dateutil-2.6.1.tar.gz

Here is the requirement for webui2 :

for i in bottle pymongo requests arrow passlib; do pip list |grep ${i}; done
bottle (0.12.8)
pymongo (3.7.2)
requests (2.20.0)
arrow (0.12.1)
passlib (1.7.1)

Some information about the installation/configuration :

[shinken@localhost ~]$ shinken --version
shinken 2.4.3
[shinken@localhost ~]$ shinken inventory
simple-log

[shinken@localhost shinken]$ ls /var/lib/shinken/modules/

[shinken@localhost modules]$ cat /etc/shinken/brokers/broker-master.cfg |grep module
# Interesting modules that can be used:

Here is my /var/log/shinken/brokerd.log

Can someone please help me ? :) Thanks

I'm sorry but I don't think anyone will be able to provide you with support for Python 2.6. WebUI is not meant to run on it.

I'm trying to find a workaround, webui (not the v2) seems to work with it. Broker seems to display warnings (like No module named bottle ?!?!) but I can have access to the web interface.

How can I download the webui (v1) tar.gz ??? I will need it for a local install (a server without access to the net)

Thanks for the answers

This problem should be fixed with the most recent develop branch. The frontend module that caused this error with an old python version has been removed
