How to install multiple python packages at once using pip

Question

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) 

Answer 1

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

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 - eg (based on having installed wsgiref and boto in a clean virtualenv):

$ pip freeze
boto==2.3.0
wsgiref==0.1.2

Answer 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

Answer 3

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.

Answer 4

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

Answer 5

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

Answer 6

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.

Answer 7

给出与安装单个模块时使用的命令相同的命令，仅通过空格分隔格式传递它

Answer 8

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

pip install <package_1> <package_2>
