I set the python operating environment on OSX Yosemite (pyenv + pip)

echo 'if [ -d "${PYENV_ROOT}" ]; then' >> ~/.zshrc
echo '    export PATH=${PYENV_ROOT}/bin:$PATH' >> ~/.zshrc
echo '    eval "$(pyenv init -)"' >> ~/.zshrc
echo 'fi' >> ~/.zshrc
exec $SHELL -l```

 4) Install a specific version of python with pyenv

#### **`pyenv install 3.4.2`**

 6) Install pip with easy_install
```sudo easy_install pip```

 7) Confirm (in the directory where version was determined in step 5)
```which python```
/Users/Owner/.pyenv/shims/python

```python --version```
Python 3.4.2

```which easy_install```
/Users/Owner/.pyenv/shims/easy_install

```easy_install --version```
setuptools 2.1

```pip --version```
pip 1.5.6 from /Users/Owner/.pyenv/versions/3.4.2/lib/python3.4/site-packages (python 3.4)


 The following is difficult to understand
 1) When using pip, easy_install is used only when installing pip.
 It's like buying Windows and not using IE after first installing Chrome in IE.
 Because pip is a partial replacement for easy_install.

 2) When installing pip, permission is denied without sudo. To touch directories that root needs.
