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 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
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.
