Hi Ivan,

 

Looks like you missed a command (or maybe a copy/paste gone bad). You are missing the ". bin/activate". The full set of commands needed is:

 

cd /opt/esmond

source /opt/rh/python27/enable

/opt/rh/python27/root/usr/bin/virtualenv --prompt="(esmond)" .

. bin/activate

python esmond/manage.py add_ps_metadata_post_user rrze197

 

Hope that helps,

Andy

Dear group,

 

In an attempt to setup the centralized MA on a pS TK 3.4, I stumbled on the following error:

 

Welcome to the perfSONAR Toolkit v3.4

 

You may create accounts to manage this host through the web interface by running the following as root:

 

  /opt/perfsonar_ps/toolkit/scripts/nptoolkit-configure.py

 

The web interface should be available at:

 

https://psps-test2-mgmt.rrze.uni-erlangen.de/toolkit

[root@ps-ps-2 ~]# cd /opt/esmond

[root@ps-ps-2 esmond]# source /opt/rh/python27/enable

[root@ps-ps-2 esmond]# /opt/rh/python27/root/usr/bin/virtualenv --prompt="(esmond)" bin/active

[root@ps-ps-2 esmond]#

[root@ps-ps-2 esmond]#

[root@ps-ps-2 esmond]# python esmond/manage.py add_ps_metadata_post_user rrze197

Traceback (most recent call last):

  File "esmond/manage.py", line 2, in <module>

    from django.core.management import execute_manager

ImportError: No module named django.core.management

 

 

After I dug a bit realizing the problem is the python environment, I tried this….but again with no luck on resolution:

 

 

[root@ps-ps-2 esmond]# yum install Django14.noarch

[root@ps-ps-2 esmond]# python esmond/manage.py add_ps_metadata_post_user rrze197

Traceback (most recent call last):

  File "esmond/manage.py", line 2, in <module>

    from django.core.management import execute_manager

ImportError: No module named django.core.management

 

 

 

Then I found those steps:

 

$ sudo apt-get install python-setuptools python-dev build-essential

$ sudo easy_install -U pip

$ sudo pip install virtualenv virtualenvwrapper

$ mkdir ~/.virtualenvs

$ sudo cat >> ~/.bashrc << EOF

# virtualenvwrapper setup

export WORKON_HOME=~/.virtualenvs

export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages --python=python2.7'

source /usr/local/bin/virtualenvwrapper.sh

EOF

$ source ~/.bashrc

$ mkvirtualenv test

$ pip install django

 

The problem is that I have none to very little knowledge on python and I am not sure how relevant is this solution.

 

Best regards,

Ivan
