Error trying to install matplotlib in Windows

Question

I'm trying to install matplotlib for Python 3.10 in Windows. Im using pip: pip install matplotlib I've already installed NumPy, Cython, Pillow and other libraries needed. But it shows this error:

error: Failed to download any of the following: ['http://www.qhull.org/download/qhull-2020-src-8.0.2.tgz'].  Please download one of these urls and extract it into 'build/' at the top-level of the source repository.

I've downloaded the said library and copied it in .cache/matplotlib/build but it doesnt work.

Any idea?

So as @FlyingTeller commented, there are no stable realeses of matplotlib so using --pre fixed the problem.
