Error failed building wheel for pycairo

Still having problems here, now on a fresh setup of my own.

I’m trying to set up dependencies to build, fix, and check fonts with fontmake, gftools, and fontbakery, as documented at https://github.com/thundernixon/googlefonts-qa-template. However, I’m getting caught in the step of installing gftools, again on this error.

I noticed three lines in particular:

Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libffi', required by 'gobject-2.0', not found

So I went into a new terminal and typed:

▶ brew install libffi
Warning: libffi 3.2.1 is already installed and up-to-date
To reinstall 3.2.1, run `brew reinstall libffi`

Things still didn’t work, so I ran:

I followed the advice here and opened my ~/.bash_profile to add:

export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"

I then tried to install gftools again, and it failed again with a message about incorrect dependency versions. So, from the numbers it requested, I ran another pip install:

(venv) 
~/type-repos/opensans  master ✗                                                                                                                                
▶ pip install -U Pillow==5.4.1 idna==2.8 requests==2.21.0 urllib3==1.24.1

Then tried to install gftools once more. And now gftools seems to have installed correctly.

So, @bghryct, I’m not sure if you’ve worked on this again yet, but it seems that for me, the magic step was brew reinstall libffi. However, the main thing was reading through the error messages and trying to follow the suggestions. Not ideal, but hopefully this helps a bit.

Failed to build pycairo
ERROR: Could not build wheels for pycairo, which is required to install pyproject.toml-based projects

all the libraries are installed accept the pycairo library. It’s just showing this to install pyproject.toml error. Infact I have already done pip install pyproject.toml and it is installed then also it’s showing the same error.

Solution

apt-get install sox ffmpeg libcairo2 libcairo2-dev
apt-get install texlive-full
pip3 install manimlib  # or pip install manimlib

Then:

pip3 install manimce  # or pip install manimce

And everything works.

The problem
This question is cut from a long paragraph and the full text is as follows, it is a problem encountered using pip3 or pip-review upgrade

pygobject==3.34.0 is available (you have 3.26.1)
Defaulting to user installation because normal site-packages is not writeable

The solution
As for the package upgrade problem – V2EX, it is said that the PIP or pip3 upgrade will have problems, because the dependency of libgirepository1.0-dev is missing, install

sudo apt-get install libgirepository1.0-dev

And then one less than code>, cario less than /code>

sudo apt-get install python-cairo
sudo apt-get install libcairo2

You are using pip version 10.0.1, however version 18.1 is available.

Can anyone tell me why and how to fix it? Using python 2.7 btw.
