I believe your problem is due to using python2.5. Is it possible to update to python2.6? Using the version of python provided by the EPEL repository is most likely to work. </p> http://www.datastax.com/support-forums/topic/opscenter-install-error-1#post-621 Tue, 08 Nov 2011 05:19:02 +0000 Anonymous 621@http://www.datastax.com/support-forums/ <p>Hi,</p> <p>I am trying to install OpsCenter on RedHat 64byte Linux and it is giving me following error. </p> <p>Below is my environment.</p> <p>1018 &gt;java -version<br /> java version "1.6.0_21"<br /> Java(TM) SE Runtime Environment (build 1.6.0_21-b06)<br /> Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)<br /> /root/datastax/opscenter-1.3<br /> 1019 &gt;iostat -V<br /> sysstat version 7.0.2<br /> (C) Sebastien Godard<br /> /root/datastax/opscenter-1.3<br /> 1020 &gt;which openssl<br /> /opt/CollabNet_Subversion/bin/openssl<br /> /root/datastax/opscenter-1.3<br /> 1021 &gt;python -V<br /> Python 2.5.6<br /> /root/datastax/opscenter-1.3<br /> 1022 &gt;</p> <p>1017 &gt;opscenter &amp;<br /> [2] 9802<br /> /root/datastax/opscenter-1.3<br /> 1018 &gt;Traceback (most recent call last):<br /> File "./bin/twistd", line 18, in &lt;module&gt;<br /> from twisted.scripts.twistd import run<br /> File "/root/datastax/opscenter-1.3/lib/py-redhat/2.6/amd64/twisted/scripts/twistd.py", line 11, in &lt;module&gt;<br /> from twisted.application import app<br /> File "/root/datastax/opscenter-1.3/lib/py-redhat/2.6/amd64/twisted/application/app.py", line 7, in &lt;module&gt;<br /> from twisted.python import runtime, log, usage, failure, util, logfile<br /> File "/root/datastax/opscenter-1.3/lib/py-redhat/2.6/amd64/twisted/python/log.py", line 17, in &lt;module&gt;<br /> from zope.interface import Interface<br /> File "/root/datastax/opscenter-1.3/lib/py-redhat/2.6/amd64/zope/interface/__init__.py", line 58, in &lt;module&gt;<br /> _wire()<br /> File "/root/datastax/opscenter-1.3/lib/py-redhat/2.6/amd64/zope/interface/interface.py", line 805, in _wire<br /> classImplements(Attribute, IAttribute)<br /> File "/root/datastax/opscenter-1.3/lib/py-redhat/2.6/amd64/zope/interface/declarations.py", line 447, in classImplements<br /> spec = implementedBy(cls)<br /> TypeError: zope.interface.declarations.Implements is not a type</p> <p>Pl. suggest how to fix this. </p> <p>Thanks,<br /> Chandresh </p>
