I know it's an easy way of doing it but i didn't find it neither here nor on google. So i was curious if there is a way to install multiple packages using pip. Something like: 

pip install progra1 , progra2 ,progra3 ,progra4 .

or:

pip install (command to read some txt containing the name of the modules)

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

    "space-delimited list" does not seem to work for me if there are dependencies between the packages, eg: `sudo -H pip install setuptools trezor` causes this error: "Could not import setuptools which is required to install from a source distribution. Please install setuptools.". Instead, I need to run as 2 separate commands. – Jonathan Cross Nov 09 '17 at 14:15
  • Does this `pip install wsgiref boto` install the libraries with their dependencies as well? – mockash Feb 27 '20 at 09:23

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

  • Do you have to specify the version #? In other words, if you just put `Django` on one line, would it automatically install the latest version? – Jon Grah Sep 15 '19 at 05:07

    You don't have to specify a version number, and generally don't need to, though which version exactly `pip` then installs is sometimes hard to predict, especially if you have configured `pip` with multiple source indices and/or configuration options which constrain which packages can be installed. A common need is to specify a minimum version requirement, like `pip >= 9.0` – tripleee Sep 28 '19 at 12:29

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.

  • Must I specify the version or can I just have `Django` on its own line and expect to get the latest version? Thanks. – PatrickT Feb 11 '22 at 18:25

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

On the command line if you have a few packages to install, You may just do

pip install <package_1> <package_2>

Complementing the other answers, you can use the option --no-cache-dir to disable caching in pip. My virtual machine was crashing when installing many packages at once with pip install -r requirements.txt. What solved for me was:

pip install --no-cache-dir -r requirements.txt

You can simply place multiple name together separated by a white space like

C:\Users\Dell>pip install markdown django-filter

#c:\Users\Dell is path in my pc this can be anything on yours

this installed markdown and django-filter on my device. enter image description here
