ImportError: No module named xxx

[zzxwill]

Hi Praneet. In you file https://github.com/Juniper/contrail-heat/blob/master/contrail_heat/resources/vn_subnet.py, there is a line "from contrail_heat.resources import contrail". What I did is the same as you for the heat resource plugin, but I hit "ImportError: No module named def_heat_plugin.client" when I wrote "from def_heat_plugin.client import constants as const". Any suggestions? Thanks.

Hi, what is def_heat_plugin? is it a resource under /usr/lib/heat/ ?
if you want to import it , put your new resource file under /usr/lib/python2.7/dist-packages/
let me know if it works ...

Hi Praneet. def_heat_plugin is a heat resource type plugin. Yes, I copied the package to /usr/lib/heat/.

It works if I put the plugin under /usr/lib/python2.6/site-packages/. But it's not way I'd like it to work.

According to the directions of Openstack Official Heat/Plugins wiki https://wiki.openstack.org/wiki/Heat/Plugins, we only need "To install a plugin, copy the Python modules to one of the configured plugin directories. Note that heat-engine must be restarted after this in order to load the new plugins." But I hit the issue if I don't copy the plugin to site-packages. Here is the directory tree of my plugin. Only modules in resource/cms/ are subclass of Resources.

---def_heat_plugin
| README.txt
| init.py
|
+---client
| def_client.py
| constants.py
| meta_client.py
| socks.py
| init.py
|

| logging.conf

Hi Zheng,
This looks like more of a python issue. You have to make sure that the
path you are putting your heat plugin files , it can be imported by python.
The default import path is "/usr/lib/python2.6/site-packages/", you have
explicitly tell python what path you want to import.

Try something this ...

import sys

sys.path.append( )

import Bar
