Ipython (0.13) interpreter won't start

[Jonno]

I just cloned Spyder source today after installing IPython 0.13 on a fresh Win7 install.

After doing a "python bootstrap.py -- --reset" then trying to open an IPython kernel I get:

[IPKernelApp] To connect another client to this kernel, use:

[IPKernelApp] --existing kernel-2528.json

Anyone have any ideas on this?

I am running spyder from source under ubuntu, with Ipython 0.13, and I don't have any problems. Does Ipython work correctly on its own?

From the error message, it sounds like a problem with the way that Ipython is monkey-patched by spyder.

[Jonno]

Hmm,

Well Ipython starts just fine on it's own but it seems the problem exists whenever Spyder or Pythonxy try to start it.

The following 2 methods (installed via pythonxy 2.7.2.3) both fail if that helps.

"C:\Program Files (x86)\pythonxy\console\Console.exe" -t "IPython (mlab)"

"C:\Program Files (x86)\pythonxy\console\Console.exe" -t "IPython (Qt)"

Figured it out.

I had installed Spyder via Pythonxy at first. Then renamed the spyderlib dir, pulled the Spyder source and was running from bootstrap.py without ever having run python setup.py install. Once I ran that I was able to run spyder either from bootstrap or from the built method and the IPython kernel works both ways.
