How to Install a Python Package With a .Whl File

How do I install a Python package with a .whl file?

I just used the following which was quite simple. First open a console then cd to where you've downloaded your file like some-package.whl and use

pip install some-package.whl

Note: if pip.exe is not recognized, you may find it in the "Scripts" directory from where python has been installed. If pip is not installed, this page can help:

Note: for clarification

If you copy the *.whl file to your local drive (ex. C:\some-dir\some-file.whl) use the following command line parameters --

pip install C:/some-dir/some-file.whl

Wheel file installation

You normally use a tool like pip to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.

For this to work, you do need to install the wheel package:

pip install wheel

You can then tell pip to install the project (and it'll download the wheel if available), or the wheel file directly:

pip install project_name  # discover, download and install
pip install wheel_file.whl  # directly install the wheel

The wheel module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:

python -m wheel install wheel_file.whl

Also see the wheel project documentation.

How to install multiple .whl files in the right order

This directory full of wheel distribution files that you created is sometimes called a wheelhouse. They are often used to make repeatable and/or offline installations.

A common way to install from a wheelhouse is:

python -m pip install --no-index --no-deps path/to/wheelhouse/*.whl

If all the wheels for all dependencies and their dependencies are in the wheelhouse, then the installation order does not matter and there is no need to connect to any remote package index (for dependency resolution, etc.). That is why we can use the --no-deps and --no-index flags.

Reference:

"Installation Bundles" section of pip's documentation

Aside:

Only now I fully appreciate the genius of pip and how it figures out the dependency tree on its own and manages to install every package in the right order.

pip's dependency resolver is resolvelib. There is a simple example on its source code repository showing how to use it to solve for wheels on PyPI.

Pip Installing .whl files from requirements.txt Python

You can just refer to local file in requirement file this way:

./TA_Lib-0.4.24-cp37-cp37m-win_amd64.whl

How to install python packages from whl files

I found the solution here. My pip version was old. I upgraded it with:

python -m pip install --upgrade pip

Everything works fine now.
