Hello,

Hey Piero,

this is a problem of an interaction between pip and your NFS mount. Some explanation of what happens can be found here:

Stuff I can think of right now you could try to resolve this:

  1. Use conda to install obspy - it installs things in a very different fashion that might not show this behavior.

  2. Talk to your admin.

  3. Install to a non-NFS mount on your server. There should be some local hard disc you can use.

Cheers!

Hey Lion,

I give you my solution in case someone will have the same problem.

The issue is compiling lxml. I added a dev package to let lxml to compile and now it does install using the virtualenv.

Thanks
Piero
