Installing Python packages from local file system

Question

Is it possible to install packages using pip from the local filesystem?

I have run python setup.py sdist for my package, which has created the appropriate tar.gz file. This file is stored on my system at /srv/pkg/mypackage/mypackage-0.1.0.tar.gz.

Now in a virtual environment I would like to install packages either coming from pypi or from the specific local location /srv/pkg.

Is this possible?

PS I know that I can specify pip install /srv/pkg/mypackage/mypackage-0.1.0.tar.gz. That will work, but I am talking about using the /srv/pkg location as another place for pip to search if I typed pip install mypackage.

Answer 1

This is very simple. The command you need is:

pip install -e <DIRECTORY>

Note that the directory must have a setup.py file in it

Answer 2

What about::

pip install --help
...
  -e, --editable <path/url>   Install a project in editable mode (i.e. setuptools
                              "develop mode") from a local project path or a VCS url.

eg, pip install -e /srv/pkg

where /srv/pkg is the top-level directory where 'setup.py' can be found.

I am pretty sure that what you are looking for is called --find-links option.

Though you might need to generate a dummy index.html for your local package index which lists the links to all packages. This tool helps:

I am installing pyfuzzybut is is not in PyPI; it returns the message: No matching distribution found for pyfuzzy.

I tried the accepted answer

pip install  --no-index --find-links=file:///Users/victor/Downloads/pyfuzzy-0.1.0 pyfuzzy

But it does not work either and returns the following error:

Ignoring indexes: https://pypi.python.org/simple Collecting pyfuzzy Could not find a version that satisfies the requirement pyfuzzy (from versions: ) No matching distribution found for pyfuzzy

At last , I have found a simple good way there: https://pip.pypa.io/en/latest/reference/pip_install.html

Install a particular source archive file.
$ pip install ./downloads/SomePackage-1.0.4.tar.gz
$ pip install http://my.package.repo/SomePackage-1.0.4.zip

So the following command worked for me:

pip install ../pyfuzzy-0.1.0.tar.gz.

Hope it can help you.

Having requirements in requirements.txt and egg_dir as a directory

you can build your local cache:

$ pip download -r requirements.txt -d eggs_dir

then, using that "cache" is simple like:

$ pip install -r requirements.txt --find-links=eggs_dir

Answer 6

An option --find-links does the job and it works from requirements.txt file!

You can put package archives in some folder and take the latest one without changing the requirements file, for example requirements:

.
└───requirements.txt
└───requirements
    ├───foo_bar-0.1.5-py2.py3-none-any.whl
    ├───foo_bar-0.1.6-py2.py3-none-any.whl
    ├───wiz_bang-0.7-py2.py3-none-any.whl
    ├───wiz_bang-0.8-py2.py3-none-any.whl
    ├───base.txt
    ├───local.txt
    └───production.txt

Now in requirements/base.txt put:

--find-links=requirements
foo_bar
wiz_bang>=0.8

A neat way to update proprietary packages, just drop new one in the folder

In this way you can install packages from local folder AND pypi with the same single call: pip install -r requirements/production.txt

PS. See my cookiecutter-djangopackage fork to see how to split requirements and use folder based requirements organization.
