_sysconfigdata_nd.py missing in /usr/lib/python2.7/

[Mar-castelluccio]

The file is present on Debian.
This is causing virtualenv to fail, and probably other modules too.

$ dpkg -S _sysconfigdata_nd.py
libpython2.7-minimal:amd64: /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py

so it's there, and no, the (closed) Debian issues are not related. so what are you trying to report?

This is the build log, when I try to build Firefox:

Moving the file from /usr/lib/python2.7/plat-x86_64-linux-gnu to /usr/lib/python2.7 solved my problem.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel Holbert (dholbert)]

Marco's workaround in comment 4 here fixed the problem for me, too (though I used a symlink instead of moving the file).

Specifically, I ran these commands:
  cd /usr/lib/python2.7
  ln -s plat-x86_64-linux-gnu/_sysconfigdata_nd.py .
and I was able to build firefox after doing that.

[Dimitri John Ledkov (xnox)]

Python has been recently multiarched, virtualenv should be fixed to include multiarch python locations.
The comment #4 nor #7 are not "fixes" they just break co-installing python for multiple architectures.

[Mar-castelluccio (mar-castelluccio)]

No one said they are fixes. They are workarounds. However the problem was in the in-tree virtualenv in the Firefox source code.

[Dimitri John Ledkov (xnox)]

Cool, thanks for the update.

[Dražen Lučanin (kermit666)]

Yup, as Mar-castelluccio said - the problem could be in the currently packaged version of virtualenv. After upgrading to the latest version in the Cheese shop

    sudo pip install --upgrade virtualenv

the problem seems to be fixed.

[Karel Vervaeke (karel-vervaeke)]

sudo pip install --upgrade virtualenv did not seem to solve the problem in my case.
The workaround from comment #4 did.

[Roberto Longobardi (seccanj)]

With lubuntu 13.04, "sudo pip install --upgrade virtualenv" actually resolves the problem.

You will need to install pip, using "sudo apt-get install python-pip" first.

[arky (arky)]

Here is workaround for 13.04

cd /usr/lib/python2.7
sudo ln -s plat-x86_64-linux-gnu/_sysconfigdata_nd.py .

[Wim Feijen (wimfeijen)]

sudo pip install --upgrade virtualenv
works for me, on Ubuntu 13.10. Thanks!

[Julien Eid (jeid64)]

This is still a confirmed issue for us on 13.04 and 14.04. Debian has a fix merged already for multiple months and the workaround is not very good for those who need to package their applications and cannot update virtualenv using pip or mess with /usr/lib/python. Is it possible we can get the fix from Debian merged?
