How to install multiple python packages at once using pip

For installing multiple packages on the command line, just pass them as a space-delimited list, e.g.:

pip install wsgiref boto

For installing from a text file, then, from pip install --help:

-r FILENAME, –requirement=FILENAME

Install all the packages listed in the given requirements file. This option can be used multiple times.

Take a look at the pip documentation regarding requirements files for their general layout and syntax – note that you can generate one based on current environment / site-packages with pip freeze if you want a quick example – e.g. (based on having installed wsgiref and boto in a clean virtualenv):

$ pip freeze
boto==2.3.0
wsgiref==0.1.2
