Unable to pip install packages in Anaconda

Question

Just downloaded and installed anaconda 3.6.2 on Mac OSX Mavericks and I need to install a package seaborn which is not pre-installed with anaconda.

$ conda install seaborn
Fetching package metadata: ..
Error: No packages found in current osx-64 channels matching: seaborn

You can search for this package on Binstar with

    binstar search -t conda seaborn

You may need to install the Binstar command line client with

    conda install binstar

Next I tried to use pip to install the package

$ which pip
/Users/username/anaconda/bin/pip

$ pip install seaborn
Could not find an activated virtualenv (required).

Tried activating root Anaconda env again, but still does not work

$ source activate root
discarding /Users/username/anaconda/bin from PATH
prepending /Users/username/anaconda/bin to PATH

$ pip install seaborn
Could not find an activated virtualenv (required).

Next I tried activating a virualenv and pip install works.

workon testEnv
pip install seaborn

Now I launched iPython notebook from Anaconda's launcher. But the seaborn package does not seem to be found!

Was the seaborn package really installed?

In ~/bashprofile, I have:

# virutalenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
source /Users/username/.virtualenvs/datasci/bin/virtualenvwrapper.sh

# added by Anaconda 2.0.1 installer
export PATH="/Users/username/anaconda/bin:$PATH"

---

Update

Removed the 2 virtualenvwrapper lines, reloaded .bash_profile, but pip install still gives the error Could not find an activated virtualenv (required). Activating another conda environment source activate testenv does not help.

$ source activate ~/.bash_profile
$ pip install seaborn
Could not find an activated virtualenv (required).

$ source activate testenv
discarding /Users/username/anaconda/bin from PATH
prepending /Users/username/anaconda/envs/testenv/bin to PATH
$ pip install seaborn
Could not find an activated virtualenv (required).

Answer 1

You need to install the anaconda version of pip. Just run:

conda install pip

This will install pip inside of the activated conda environment
