[IPython-dev] Installation docs out of date

[Ryan Nelson]

Yeah. The docs (http://ipython.org/install.html) should probably mention
this if they are going to reference conda specifically. However, it is a
conda-specific issue, so it might be more appropriate to point users to the
continuum documentation instead. Especially, given that the IPython docs
suggest installing the full Anaconda package (which has notebook) and do
not mention Miniconda, which it looks like you are using. You can search
the conda package repository pretty easily:
http://conda.pydata.org/docs/examples/search.html
But I agree that this it is not well documented.

I have miniconda on a Linux distro, and fresh environments don't install
pip. This caused some problems for me at first because it was using the
system pip, which was no good. Do you have another Python install on your
computer? You could do a `conda install pip` and make sure you have the
Continuum version.

Just out of curiosity, why would use want to use pip at all? It might be
safer to install things using conda exclusively. You might run into
problems with pip when you are trying to install modules that require
compiled components such as Qt4/5. For example, the command `conda install
ipython ipython-notebook ipython-qtconsole` will install ipython and all
the dependencies, including a precompiled version of the Qt libraries. I
don't think a `pip install pyqt4` will do that. (?)  See here for more:
http://stackoverflow.com/questions/20994716/what-is-the-difference-between-pip-and-conda
However, the answer here is a little misleading because the conda-installed
pip will install packages that are conda-aware. That is, I've installed
packages with the conda version of pip, and `conda list` will show these
packages as being installed.
