WeasyPrint 0.42 depends on:
- CPython ≥ 3.4
- cairo ≥ 1.15.0 
- Pango ≥ 1.29.3
- CFFI ≥ 0.6
- html5lib ≥ 0.999999999
- cairocffi ≥ 0.5
- tinycss2 ≥ 0.5
- cssselect2 ≥ 0.1
- CairoSVG ≥ 1.0.20
- Pyphen ≥ 0.8
- pdfrw ≥ 0.4
- Optional: GDK-PixBuf ≥ 2.25.0 
Python, cairo, Pango and GDK-PixBuf need to be installed separately. See platform-specific instructions for Linux, OS X and Windows below.
virtualenv ./venv . ./venv/bin/activate pip install WeasyPrint
Now let’s try it:
weasyprint --help weasyprint http://weasyprint.org ./weasyprint-website.pdf
You should see warnings about unsupported CSS 3 stuff; this is expected. In the PDF you should see the WeasyPrint logo on the first page.
You can also play with WeasyPrint Navigator. Start it with
python -m weasyprint.navigator
|||cairo ≥ 1.15 is best but older versions may work too. The test suite passes on cairo 1.12 and 1.14, and passes with some tests marked as “expected failures” on 1.8 and 1.10 due to behavior changes or bugs in cairo. With cairo 1.14, WeasyPrint sometimes creates PDF files that may not be correctly interpreted by GhostScript or CUPS.|
|||Without it, PNG and SVG are the only supported image formats. JPEG, GIF and others are not available.|
Pango, GdkPixbuf, and cairo can not be installed
with pip and need to be installed from your platform’s packages.
CFFI can, but you’d still need their own dependencies.
This section lists system packages for CFFI when available,
the dependencies otherwise.
CFFI needs libffi with development files. On Debian, the package is called
If your favorite system is not listed here but you know the package names, tell us so we can add it here.
Debian / Ubuntu¶
Debian 9.0 Stretch or newer, Ubuntu 16.04 Xenial or newer:
sudo apt-get install build-essential python3-dev python3-pip python3-cffi libcairo2 libpango-1.0-0 libpangocairo-1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info
WeasyPrint is packaged for Fedora, but you can install it with pip after installing the following packages:
sudo yum install redhat-rpm-config python-devel python-pip python-cffi libffi-devel cairo pango gdk-pixbuf2
WeasyPrint is available in the AUR, but you can install it with pip after installing the following packages:
sudo pacman -S python-pip cairo pango gdk-pixbuf2 libffi pkg-config
WeasyPrint is automatically installed and tested on virtual macOS machines. The official installation method relies on Homebrew:
brew install python3 cairo pango gdk-pixbuf libffi
Don’t forget to use the pip3 command to install WeasyPrint, as pip may be using the version of Python installed with macOS.
You can also try with Macports, but please notice that this solution is not tested and thus not recommended (also known as “you’re on your own and may end up crying blood with sad dolphins for eternity”):
sudo port install py-pip cairo pango gdk-pixbuf2 libffi
Dear Windows user, please follow these steps carefully.
Really carefully. Don’t cheat.
