How to use Python's pip to download and keep the zipped files for a package?

Question

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.

Solution 1

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

 pip download <package-name>

Solution 2

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.

Solution 3

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

Solution 4

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

Solution 5

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.

Nice, that did indeed work - although I tagged a --no-install option on. And you're right about the funky filenames, but at least the files are there.

[Mohammad Niknam]

last time I checked , --download option download the package with dependencies.

[Mark Gemmill]

@Danial - yes, as of version 1.1, --download now downloads dependancies.

[John C]

As of version 1.5 (possibly earlier), pip has a --no-deps option, to prevent downloading dependencies.

[ostler.c]

--download-cache is deprecated. use pip install --download <dir> <pkg>

[Sнаđошƒаӽ]

pip install --download in now deprecated, and will be removed from pip 10. pip.pypa.io/en/latest/reference/pip_download/#overview. Use pip download somepackage.

[rrauenza]

Specifically, the new equivalent is pip download -d <dir> { -r requirements.txt | <packagename> }

[knocte]

@rrauenza what is the requirements.txt for?

[knocte]

and how to install the downloaded packages later?

[KJ50]

This is the most up-to-date answer. Thanks

[Anton Khodak]

@knocte pip install path-to-downloaded-package

[knocte]

tried that some days ago and I think it still tried to retrieve deps from the internet instead of using the downloaded ones; IIRC, I had to use sudo pip install <path-to-downloaded-package> --no-index --find-links `pwd`

Note that pip download also supports -r requirements.txt so you can easily download them all from an internet-connected machine then copy to an offline machine and install how the above commenters mentioned

[cwhisperer]

I have to develop in windows and deploy on RH7 with no internet connection at all. So I download the source packages with --no-binary :all: . However this fails when Collecting django-pyodbc-azure==2.0.4.1 as this package has no source. Is there a way to download the source or if this does not exist, to download the weehl?

[Admin]

I think the option changed to --cache-dir not --download-cache can someone verify

[Vic]

or pip download -d <target dir> <package> to download to a specific directory. All dependencies are also downloaded.

[John C]

Moved the checkmark from here, as the other answer is more up-to-date, sorry. Time marches on.

[Prometheus]

if you dont specify the platform, it will download the files for the current OS. Therefore this will not work if you install the downloaded files on other OS

[stackprotector]

Can you specify a version of the package without using -r requirements.txt?
