pygments dependency injection

[anatoly techtonik]

Hi guys,

I've noticed that Spyder now doesn't run without pygments. Is that intentional? Can we make the dependency optional?

Spyder 2.3.3

IPython 3

without pygments, spyder causes python to crash on windows,

hard for user to know what the issue is since there is no feedback,

and crash windows have strong negative association.

Spyder dialog says to use `spyder --reset`,

but that doesn't work since it's not the issue

please either

* make pygments required during installation

or

* handle ImportError gracefully

  - fall back to python interpreter console

  - issue message

Thanks!

Hi,

How did you install Spyder? What is the error that you're seeing?

The error would be helpful to provide a better handling mechanism for Pygments.

Cheers,
Carlos

Carlos:

I am getting this error too. Here's the details:

Running Python 2.7.10 - 32-bit on Windows 7 Professional

I manually installed spyder by first installing the dependencies, as per the install webpage. No issues with installing those.

I then installed Spyder and clicked on the icon. It crashed as shown in the previous poster's description. Here's the error from the crash log:

Traceback (most recent call last):
  File "C:\Python27\lib\site-packages\spyderlib\spyder.py", line 2336, in main
    mainwindow = run_spyder(app, options, args)
  File "C:\Python27\lib\site-packages\spyderlib\spyder.py", line 2220, in run_spyder
    main.setup()
  File "C:\Python27\lib\site-packages\spyderlib\spyder.py", line 766, in setup
    from spyderlib.plugins.inspector import ObjectInspector

    from spyderlib.widgets.ipython import IPythonControlWidget

    from IPython.frontend.qt.console.pygments_highlighter import RegexLexer
ImportError: No module named pygments_highlighter

I have successfully loaded Spyder before, but now that I'm using 32-bit, it seems to be an issue.

Since this seems to be an IPython problem, what version of IPython are
you running?

FYI, IPython is in constant large scale flux at the moment so it is not
surprising that there are issues. It has gotten to the point I am
seriously looking at other options. Seems money is 'the root of all evils':)

Hi,

If you installed Spyder *this morning*, you need to run

    pip install qtconsole

to install the Jupyter (previously IPython) component that Spyder depends on

Just running

    pip install ipython

installs now the terminal (i.e. cmd.exe) version of IPython.


You can read more about what happened to the IPython project (and the transition to Jupyter) here:

Cheers,
Carlos

Thanks Carlos. I ended up just using the Anaconda distribution - it also had problems starting up, but it puts a nice little icon  "Reset Spyder" in the start menu...did the trick!

The whole IPython vs Jupyter ect is very confusing...thanks for the link!

Agreed. The link was interesting, but the information in it was clear as
mud. Basically, as I see it, the project blew up the IPython namespace
without a clear way forward. Personally I think if you use IPython for
Python, nothing should change and you should not have to care about
Jupyter.
