How to install a Python package from within IPython?
See the accepted answer from @Chronial which is the best way to do this in modern ipython or jupyter (as of 2018) is to use the %pip
magic:
%pip install my_package
The answer below from 2011 is now outdated: See the accepted answer for an easier way to do this in modern jupyter.
You can use the !
prefix like this:
!pip install packagename
The !
prefix is a short-hand for the %sc
command to run a shell command.
You can also use the !!
prefix which is a short-hand for the %sx
command to execute a shell command and capture its output (saved into the _
variable by default).
import pip
pip.main(['install', 'package_name'])
The above shell-based answers don't work unless pip
is in your $PATH (e.g. on Windows).

aculich's answer will not work in all circumstances, for example:
- If you installed ipython/jupyter in a venv and run it directly via the venv's
python
binary - If you have multiple python versions, like EntryLevelR.
The correct command is:
import sys
!{sys.executable} -m pip install requests
The best way to do this in modern ipython or jupyter is to use the %pip
magic:
%pip install my_package
