team, I able to get into the yang explorer gui but cannot login (please see screenshot below). image

OS: Ubuntu 16.04 fresh installation I followed the following steps in installing yang explorer: sudo pip install --upgrade setuptools sudo apt-get install python-virtualenv sudo apt-get install graphviz git clone https://github.com/CiscoDevNet/yang-explorer.git cd yang-explorer bash setup.sh cd /yang-explorer [sudo] ./start.sh &

Everytime I try to login, I get the following messages:

I am getting the same issue - any luck with troubleshooting it?

robertcsapo commented 6 years ago

Could you try running pip install -r requirements.txt ?

  Rolling back uninstall of lxml

lxml looks installed: 

sudo sudo pip install lxml
Requirement already satisfied: lxml in /usr/lib/python3/dist-packages

Doesn't seem to be lot of activity here. Is the project still active?

AJNOURI commented 6 years ago

Corrected the previous errors using:

apt-get install libxml2-dev libxslt1-dev python-dev
apt-get install python-lxml

But still cannot login:

Having exact issues as above on Ubuntu 16.04 -- any suggestions?

alexcherry83 commented 6 years ago

Same issue here, tried everything already, Ubuntu 16.04.4 LTS

ssaptarshi commented 6 years ago

Got a workaround for this. The Yang Explorer uses Python Virtual environment (poor man's Docker!) - through virtualenv module. This is created in the folder "v" inside the yang_explorer folder.

Somehow, graphviz is not installed on this virtualenv, when we run setup.sh. So even if one has the graphviz module installed on the system, it's not available to Yang explorer.

Here are the steps, assuming you have got the Yang explorer code in a zip archive -

  1. We need to start fresh - remove existing yang_explorer folder
  2. Recreate the yang explorer folder by unzipping the archive
  3. Run the setup script
  4. Manually activate the python virtualenv in folder v
  5. Install graphviz in the virtualenv using pip install graphviz
  6. Deactivate the virtualenv (for steps 4, 5 and 6 you may refer to https://help.dreamhost.com/hc/en-us/articles/215489338-Installing-and-using-virtualenv-with-Python-2 steps 6,7 and onward are applicable)
  7. Run the start.sh script - now the server should work as expected.

The setup.sh script needs a fix to ensure graphviz is not missed in the virtualenv setup.

chomezski commented 6 years ago

Actually I was going to say that I havent troubleshooted further - I ended up re-building the server and it worked. Assuming the above happened :) Thanks

Hi I am getting graphviz not installed error as well, and I tried to implement this workaround however when I ran setup.py , Iam getting manage.py not found error ,therefore, database does not start . I can see manage.py is there but setup.py does not get it. Did anyone ever have the same problem ?

_yang-explorer-master$ find . | grep manage.py ./v/lib/python2.7/site-packages/django/conf/project_template/manage.pyc ./v/lib/python2.7/site-packages/django/conf/projecttemplate/manage.py ./server/manage.py
