Hi Lukáš,
Frustrating, I haven't solve the problem.
Formerly， I installed the avocado and avocado_vt, and then use them.
I hadn't met any problem.
Now，I want to run it from source code on an new PC(fedora20), without
installing.
I think It's more flexible for development.
I deploy it as following,
1.Clone both avocado and avocado_vt to the same directory.
[root@localhost avocado-devel]# ls
avocado avocado-vt
2.Run 'pip install -r requirements' for both of them.
I'm sure the requirements have been updated to the latest version.
But there're some warning,
[root@localhost avocado]# pip install -r requirements.txt

3. Run 'make link' on avocado directory.
4. And then, I want to confirm whether avocado can load the avocado_vt
plugin,
so I run 'scripts/avocado plugins' on avocado-devel/avocado directory.
the following error appeared.
#scripts/avocado plugins
<---------------cut---------->
Failed to load plugin from module "avocado_vt.plugins.vt_list":
IOError(2, 'No such file or directory')
Failed to load plugin from module "avocado_vt.plugins.vt": IOError(2,
'No such file or directory')
<---------------cut---------->
*It should be noted that the plugin "vt_bootstrap" has been load
successfully.
*In fact, vt_list/vt/vt_bootstrap, all of them are placed at the same
directory.
I traced it and found it occurred at class EntryPoint.resolve(),
which is declared
at /usr/lib/python2.7/site-packages/pkg_resources/__init__.py
The call of __import__ failed for both vt_list plugin and vt plugin.
I added trace log, and then run 'scripts/avocado plugins' again.
def resolve(self):
"""
Resolve the entry point from its module and attrs.
"""
print "trace import.... ", self.module_name
module = __import__(self.module_name, fromlist=['__name__'],
level=0)
try:
return functools.reduce(getattr, self.attrs, module)
except AttributeError as exc:
raise ImportError(str(exc))
The output :
trace import.... avocado_vt.plugins.vt_list
vt-list = avocado_vt.plugins.vt_list:VTLister
trace import.... avocado_vt.plugins.vt
vt = avocado_vt.plugins.vt:VTRun
[(EntryPoint.parse('vt-list = avocado_vt.plugins.vt_list:VTLister'),
IOError(2, 'No such file or directory')),
(EntryPoint.parse('vt = avocado_vt.plugins.vt:VTRun'), IOError(2, 'No
such file or directory'))]

do you have another hints to me ?
