Spyderlib installation on RHEL 6, troubles with QtWebkit

[Ghislain Vaillant]

Hey guys,

Tried to install spyderlib v2.0.12 on my SL6.1 64 bits system, as the
requirements (PyQt, python-sphinx, pylint, pyflakes) can be fulfilled
with extra packages from EPEL. Building and installing from the
setup.py script in the source directory went fine. However spyderlib
does not start, giving the following error message in the CLI:

Traceback (most recent call last):
File "/usr/bin/spyder", line 2, in <module>
from spyderlib import spyder
File "/usr/lib/python2.6/site-packages/spyderlib/spyder.py", line 60,
in <module>
from spyderlib.plugins.inspector import ObjectInspector
File "/usr/lib/python2.6/site-packages/spyderlib/plugins/
inspector.py", line 29, in <module>
from spyderlib.widgets.browser import WebView
File "/usr/lib/python2.6/site-packages/spyderlib/widgets/browser.py",
line 11, in <module>
from spyderlib.qt.QtWebKit import QWebView, QWebPage
File "/usr/lib/python2.6/site-packages/spyderlib/qt/QtWebKit.py",
line 10, in <module>
from PyQt4.QtWebKit import *
ImportError: No module named QtWebKit

which suggests a missing python binding for QtWebkit although I
installed it and its devel package from EPEL (qtwebkit-2.1.1-1 and
qtwebkit-devel-2.1.1-1).

Any ideas ? Has anybody been successful in getting Spyder to work on
an EL6 config ?

Cheers,
Ghis

Hi,

This sounds like the PyQt package you have installed was not built
with QtWebKit Python bindings.
You should check with the package maintainer.

HTH,
Pierre

You are right. Apparently, support for QtWebkit was dropped and
bindings for
Python went missing since then.

http://pkgs.org/centos-6-rhel-6/centos-rhel-i386/PyQt4-4.6.2-8.el6.i6...

Suggestions for getting Spyderlib to work for EL6 are warmly welcome.
Any successful report ?

Thank you very much for your help.

On Fedora 16 qtwebkit package is still there.

[Ghislain Vaillant]

Indeed, and Spyder is also directly available in the Fedora 16 repo.
EL6 is based on Fedora 12 though. QtWebkit can be installed via the
EPEL 3rd party repo, which I did, but apparently the Python bindings
are broken somehow. I also tried the installation of Eric4, available
in EPEL, without success, as it imports QtWebkit python bindings as
well.

[anatoly techtonik]

If you can install QtWebkit with development files, you can build PySide from scratch. Perhaps https://github.com/PySide/BuildScripts can help you.

[Ghislain Vaillant]

Thanks Anatoly. Apparently RHEL 6 is mentioned in the
dependencies.fedora.sh. I'll try this out, get back here and update my
status.

[Ghislain Vaillant]

Just a quick update on my attempt to install the latest Spyder on EL6. I tried to build PySide from scratch following Anatoly's advice.

1) Cloned this: https://github.com/PySide/BuildScripts

2) Followed the readme instructions, that is to install all the required dependencies using the "dependencies_fedora.sh" script, do the git init & update on all submodules and finally run "build_and_install.sh"

3) On the project's CMake, I get the following output and error at the end:

Any idea how to solve this. Shall I rather post a bug report on Pyside's bugzilla ?

[anatoly techtonik]

PySide is moving to become QT Project, so I don't even know what is the best place to post:

Update on my attempt to get Spyder working on EL6.

EPEL has released an RPM in its stable repo containing the missing
bindings for QtWebkit. Now Spyder launches correctly and seems to be
working as expected.

Many thanks for everyone who contributed to this topic.

Hi everyone.

It doesn't work for me. It launches correctly, but then I can't open nor save a file:

I'm running a fully up-to-date Centos 6.2,

Any ideas?

Thanks in advance.

P.S.: By the way, just before I noticed about the existence the webkit bindings on EPEL, I'd found a workaround installing the PyQt4-4.6.2-7 from ScientificLinux, another Red Hat based distro.
