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

pip install -r requirements.txt

and in the requirements.txt file you put your modules in a list, with one item per line.

• Django=1.3.1

• South>=0.7

• django-debug-toolbar

You can install packages listed in a text file called requirements file. For example, if you have a file called req.txt containing the following text:

Django==1.4
South==0.7.3

and you issue at the command line:

pip install -r req.txt

pip will install packages listed in the file at the specific revisions.

You can use the following steps:

Step 1: Create a requirements.txt with list of packages to be installed. If you want to copy packages in a particular environment, do this

pip freeze >> requirements.txt

else store package names in a file named requirements.txt

Step 2: Execute pip command with this file

pip install -r requirements.txt
