<div>I'm using Tox with Jenkins to run several selenium tests. Everything is good but every now and then I get the follow error:</div><div><br></div><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">IOError: [Errno 2] No such file or directory: '/var/lib/jenkins/.tox/</span><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">jenkins/lib/python2.7/site-</span><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">packages/Distutils-1.0-py2.7.</span><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">egg-info'</span></div>

</font></div><div><font color="#222222" face="arial, sans-serif"><div>Installing collected packages: Distutils</div><div><br></div><div> Found existing installation: Distutils 1.0</div><div><br></div><div> Uninstalling Distutils:</div>

<div><br></div><div>So:</div><div>ToxA -> Finds the Distutils installation</div><div>ToxB -> Also finds it</div><div>ToxA -> Delete it</div><div>ToxB -> Try to delete (fails)</div><div><br></div><div>So my questions are: </div>
<div>- Why is Distutils being deleted? (noob when it comes to it)</div><div>- Is there a way to avoid this?</div><div>- How are you guys using Tox with Jenkins? I'm just calling tox -e jenkins path/to/test.py. Is there a better way?</div>
<div>- sbt and other building tools usually have locking mechanisms for these kind of things. Why doesn't Tox? (if it does, how do I turn it on?). </div><div><br></div><div>Thanks,</div></font><div>~Pedro</div>
