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

I’m having trouble installing a Python package on my Windows machine, and would like to install it with Christoph Gohlke’s Window binaries. (Which, to my experience, alleviated much of the fuss for many other package installations). However, only .whl files are available.

But how do I install .whl files?

Notes

  • I’ve found documents on wheel, but they don’t seem so staightforward in explaining how to install .whl files.
  • This question is a duplicate with this question, which wasn’t directly answered.

Answer #1:

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-dirsome-file.whl) use the following command line parameters —

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

Answer #2:

First, make sure you have updated pip to enable wheel support:

pip install --upgrade pip

Then, to install from wheel, give it the directory where the wheel is downloaded. For example, to install package_name.whl:

pip install --use-wheel --no-index --find-links=/where/its/downloaded package_name

Answer #3:

There are several file versions on the great Christoph Gohlke’s site.

Something I have found important when installing wheels from this site is to first run this from the Python console:

import pip
print(pip.pep425tags.get_supported())

so that you know which version you should install for your computer. Picking the wrong version may fail the installing of the package (especially if you don’t use the right CPython tag, for example, cp27).

Answer #4:

I am in the same boat as the OP.

Using a Windows command prompt, from directory:

C:Python34Scripts>
pip install wheel

seemed to work.

Changing directory to where the whl was located, it just tells me ‘pip is not recognized’. Going back to C:Python34Scripts>, then using the full command above to provide the ‘where/its/downloaded’ location, it says Requirement 'scikit_image-...-win32.whl' looks like a filename, but the filename does not exist.

So I dropped a copy of the .whl in Python34/Scripts, ran the exact same command over again (with the --find-links= still going to the other folder), and this time it worked.

Answer #5:

You have to run pip.exe from the command prompt on my computer.
I type C:/Python27/Scripts/pip2.exe install numpy

Answer #6:

On Windows you can’t just upgrade using pip install --upgrade pip, because the pip.exe is in use and there would be an error replacing it. Instead, you should upgrade pip like this:

easy_install --upgrade pip

Then check the pip version:

pip --version

If it shows 6.x series, there is wheel support.

Only then, you can install a wheel package like this:

pip install your-package.whl

Answer #7:

To be able to install wheel files with a simple doubleclick on them you can do one the following:

1) Run two commands in command line under administrator privileges:

assoc .whl=pythonwheel
ftype pythonwheel=cmd /c pip.exe install "%1" ^& pause

2) Alternatively, they can be copied into a wheel.bat file and executed with ‘Run as administrator’ checkbox in the properties.

PS pip.exe is assumed to be in the PATH.

Update:

(1) Those can be combined in one line:

assoc .whl=pythonwheel& ftype pythonwheel=cmd /c pip.exe install -U "%1" ^& pause

(2) Syntax for .bat files is slightly different:

assoc .whl=pythonwheel& ftype pythonwheel=cmd /c pip.exe install -U "%%1" ^& pause

Also its output can be made more verbose:

@assoc .whl=pythonwheel|| echo Run me with administrator rights! && pause && exit 1
@ftype pythonwheel=cmd /c pip.exe install -U "%%1" ^& pause || echo Installation error && pause && exit 1
@echo Installation successfull & pause

see my blog post for details.

Answer #8:

EDIT: THIS NO LONGER IS A PART OF PIP

To avoid having to download such files, you can try:

pip install --use-wheel pillow
