pip - How to install packages in different version of python? -


i have macbook pro came pre-installed python 2.7. later installed python3 , ipython notebook. installed pip install packages, , able install packages , run program python 3. however, project need run code in python 2.7, , not sure how install in python 2.7 folder.

i tried using pip installing packages 2.7, kept giving error saying package exists. when check version of python using --version, see 2 pythons installed. however, when check pip , pip3, both seem in th same folder.

any tips on how install packages in python 2.7, without making changes 3.3? using python3 , ipython notebooks project.

viveks-mbp:~ vivekyadav$ pip /library/frameworks/python.framework/versions/3.3/bin/pip viveks-mbp:~ vivekyadav$ pip3 /library/frameworks/python.framework/versions/3.3/bin/pip3

viveks-mbp:~ vivekyadav$ python /usr/bin/python viveks-mbp:~ vivekyadav$ python3 /library/frameworks/python.framework/versions/3.3/bin/python3

you can use virtualenv create kind of sandbox.

$ virtualenv <work-directory> $ source <work-directory>/bin/activate

the last command initiate virtual environment, totally isolated system. every pip command install package inside directory.

but have run application inside virtual environment too.
