As my attempts to migrate to python3 (See Switching from python2 to python3 ) continue;

Trying to install spyder with pip3 i arrived at a functioning workspace (although with no nautilus access to it, only via terminal).
Updating the system and then restarting rendered it (for some unknown reason) no longer accessible; typing spyder in terminal results in:

Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/qtpy/__init__.py", line 119, in <module>
    from PySide import __version__ as PYSIDE_VERSION  # analysis:ignore
ImportError: No module named 'PySide'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/bin/spyder", line 11, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.5/dist-packages/spyder/app/start.py", line 103, in main
    from spyder.app import mainwindow
  File "/usr/local/lib/python3.5/dist-packages/spyder/app/mainwindow.py", line 49, in <module>
    requirements.check_qt()
  File "/usr/local/lib/python3.5/dist-packages/spyder/requirements.py", line 39, in check_qt
    import qtpy
  File "/usr/local/lib/python3.5/dist-packages/qtpy/__init__.py", line 125, in <module>
    raise PythonQtError('No Qt bindings could be found')

Then, after bringing my system to spyder-free state, tried to install spyder3 with apt-get:

sudo apt-get install spyder3

which resulted in a new spyder (version 2.*) that runs python 3.

The problem is updating it to version 3.*.
pip does not recognize any 'spyder3' and so i tried

pip3 install -U spyder

resulting in, although updated, another spyder application on my computer; that is i can

which spyder3; which spyder

and get 2 different locations with spyder3 being v2.* and spyder being v3.*.

If only the "right" spyder would appear in nautilus - I could live with this oddity, but it opens up the "not updated spyder".

So to summarize things up:

  • Option A gives me a non-working spyder (and no access via nautilus).
  • Option B gives me 2 working spyder located in different places, 1 is version 2.* and accessible via nautilus, the other is version 3.* and inaccssible via nautilus.

What am i doing wrong?...

When installing spyder with pip3; PyQt4 packages was needed:

sudo apt-get install python3-pyqt4

Having installed that gave me the much wanted spyder IDE, working in version 3 and python3.5.

When launching spyder with terminal I get:

void DBusMenuExporterPrivate::addAction(QAction*, int): Already tracking action "Project explorer" under id 124

But a post in github (with a much relevant difficulty) reassured me: https://github.com/spyder-ide/spyder/issues/3521
