If I want to use the pip command to download a package (and its dependencies), but keep all of the zipped files that get downloaded (say, django-socialregistration.tar.gz) – is there a way to do that?

I’ve tried various command-line options, but it always seems to unpack and delete the zipfile – or it gets the zipfile, but only for the original package, not the dependencies.

pip install --download is deprecated. Starting from version 8.0.0 you should use pip download command:

 pip download <package-name>

The --download-cache option should do what you want:

pip install --download-cache="/pth/to/downloaded/files" package

However, when I tested this, the main package downloaded, saved and installed ok, but the the dependencies were saved with their full url path as the name – a bit annoying, but all the tar.gz files were there.

The --download option downloads the main package and its dependencies and does not install any of them. (Note that prior to version 1.1 the --download option did not download dependencies.)

pip install package --download="/pth/to/downloaded/files"

The pip documentation outlines using --download for fast & local installs.

I always do this to download the packages:

pip install --download /path/to/download/to_packagename

OR

pip install --download=/path/to/packages/downloaded -r requirements.txt

And when I want to install all of those libraries I just downloaded, I do this:

pip install --no-index --find-links="/path/to/downloaded/dependencies" packagename

OR

pip install --no-index --find-links="/path/to/downloaded/packages" -r requirements.txt

Update

Also, to get all the packages installed on one system, you can export them all to requirement.txt that will be used to intall them on another system, we do this:

pip freeze > requirement.txt

Then, the requirement.txt can be used as above for download, or do this to install them from requirement.txt:

pip install -r requirement.txt

REFERENCE: pip installer

In version 7.1.2 pip downloads the wheel of a package (if available) with the following:

pip install package -d /path/to/downloaded/file

The following downloads a source distribution:

pip install package -d /path/to/downloaded/file --no-binary :all:

These download the dependencies as well, if pip is aware of them (e.g., if pip show package lists them).

Update

As noted by Anton Khodak, pip download command is preferred since version 8. In the above examples this means that /path/to/downloaded/file needs to be given with option -d, so replacing install with download works.

Use pip download <package1 package2 package n> to download all the packages including dependencies

Use pip install --no-index --find-links . <package1 package2 package n> to install all the packages including dependencies. It gets all the files from CWD. It will not download anything

pip wheel is another option you should consider:

pip wheel mypackage -w .\outputdir

It will download packages and their dependencies to a directory (current working directory by default), but it performs the additional step of converting any source packages to wheels.

It conveniently supports requirements files:

pip wheel -r requirements.txt -w .\outputdir

Add the --no-deps argument if you only want the specifically requested packages:

pip wheel mypackage -w .\outputdir --no-deps

I would prefer (RHEL) – pip download package==version --no-deps --no-binary=:all:

installing python packages offline

For windows users:

To download into a file open your cmd and folow this:

cd <*the file-path where you want to save it*>

pip download <*package name*>

the package and the dependencies will be downloaded in the current working directory.

To install from the current working directory:

set your folder where you downloaded as the cwd then follow these:

pip install <*the package name which is downloded as .whl*> --no-index --find-links <*the file locaation where the files are downloaded*>

this will search for dependencies in that location.
