When you illustrated how twisted was properly set up, you did it with "python", but your start script runs pvpython. I wonder if maybe your system python twisted is conflicting (or overriding) with the one provided by pvpython? That's just a guess based on a quick read.<div><br></div><div>Hope this helps,</div><div>Scott</div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Fri, Mar 10, 2017 at 12:37 PM, Rodnei Couto <span dir="ltr"><<a href="mailto:rodneicouto@gmail.com" target="_blank">rodneicouto@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr"><div class="m_6750000860660712169m_4259096290913525122gmail-markdown-here-wrapper"><p style="margin:0px 0px 1.2em"><span style="font-size:12.8px">I set up my environment as indicated in </span><a href="http://kitware.github.io/paraviewweb/docs/ubuntu_14_04.html" style="font-size:12.8px" target="_blank">http://kitware.github.io/pa<wbr>raviewweb/docs/ubuntu_14_04.ht<wbr>ml</a></p><p style="margin:0px 0px 1.2em">My operational system is Ubuntu 64 14_04 LTS.</p><p style="margin:0px 0px 1.2em">When I try to run my start.sh, I get an error: </p>
