Trac crashes after installing plugin

[anonymous]

After installing plugin for single environment and enabling it through admin page, I restart the server and see the following error on any page (and nothing else):

Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/Trac-0.11dev_r6144-py2.5.egg/trac/web/api.py", line 342, in send_error

I forgot to say that I also tried to run

trac-admin /path/to/projenv upgrade

(of course, replacing path), but it hasn't done anything:

Database is up to date, no upgrade necessary.

I'm using Trac 0.11dev-r6144.

Thank you for help.

I get almost the same: (using xmlrpc plugin)

Traceback (most recent call last):

File "build/bdist.linux-i686/egg/tracrpc/web_ui.py", line 76, in get_templates_dirs

from pkg_resources import resource_filename

Any guidance are deeply appreciated

Same thing here. On Trac 0.11 I get:

Traceback (most recent call last):
  File "C:\Python25\Lib\site-packages\trac\web\api.py", line 339, in send_error
    'text/html')
  File "C:\Python25\Lib\site-packages\trac\web\chrome.py", line 651, in render_template
    template = self.load_template(filename, method=method)
  File "C:\Python25\Lib\site-packages\trac\web\chrome.py", line 627, in load_template
    self.templates = TemplateLoader(self.get_all_templates_dirs(),
  File "C:\Python25\Lib\site-packages\trac\web\chrome.py", line 390, in get_all_templates_dirs
    dirs += provider.get_templates_dirs()
  File "build\bdist.win32\egg\worklog\webui.py", line 165, in get_templates_dirs
    from pkg_resources import resource_filename
SystemError: Parent module 'worklog' not loaded

To recover I only need to remove the ini lines: worklog.webadminui.worklogadminpage = enabled worklog.webui.worklogpage = enabled

Exactly the same problem here...

Thx

Sorry, my prev post is so badly irrelevant...

I'm pretty sure this is not specific to the XmlRpcPlugin. See ​this sample code for why this error occurs.

However, I'm also not sure what the real problem is.

The same Problem for me. When i activate the part tracrpc.web_ui, the trac environment crashes with :

Traceback (most recent call last):

File "c:\python25\lib\site-packages\Trac-0.11b1-py2.5.egg\trac\web\api.py", line 339, in send_error

'text/html')

File "c:\python25\lib\site-packages\Trac-0.11b1-py2.5.egg\trac\web\chrome.py", line 651, in render_template

template = self.load_template(filename, method=method)

File "c:\python25\lib\site-packages\Trac-0.11b1-py2.5.egg\trac\web\chrome.py", line 627, in load_template

self.templates = TemplateLoader(self.get_all_templates_dirs(),

File "c:\python25\lib\site-packages\Trac-0.11b1-py2.5.egg\trac\web\chrome.py", line 390, in get_all_templates_dirs

File "build\bdist.win32\egg\tracrpc\web_ui.py", line 76, in get_templates_dirs

from pkg_resources import resource_filename

SystemError: Parent module 'tracrpc' not loaded

when is set tracrpc.web_ui to disabled, the project environment is running again.

Problem fixed in #2922

Res again:

build TracXMLRPC-0.1-py2.5.egg (xmlrpcplugin\1.0)
build TracXMLRPC-1.0.0-py2.5.egg (xmlrpcplugin\trunk)
copy both into plugins

restart service

you can resolve this also by easy_install (xmlrpcplugin\1.0) and (xmlrpcplugin\trunk)
