无法从anaconda启动ipython笔记本

Question

I have installed anaconda into my home directory and added the path to PATH os variable

and installed ipython notebook in anaconda with command

conda install ipython-notebook

it works fine

after that I opened terminal and typed in

ipython notebook

it reported

Could not start notebook. Please install ipython-notebook

Have I done something wrong on the installation?

The output of

conda list | grep ipython

is

ipython                   2.3.1                    py27_0  
ipython-notebook          2.3.1                    py27_0  
ipython-qtconsole         2.2.0                    py27_0

Answer 1

Could be a couple of things:

conda installs ipython into the active conda environment. If bash had seen a previous invocation of ipython it might have that location hashed.

Run hash -r to clear the shell hashed lookups after installing anything that places a new executable in your path. Things like:

• ipython
• pip
• binstar
• ...

Answer 2

I know this post is old but still just want to put my answer here so that it may be useful for somebody who has the same question.

Ipython notebook has become jupyter notebook with the latest installation of Anaconda (v3.x).

So going forward, the command "ipython notebook" executed either in the terminal or in the powershell will open Jupyter notebook only
