Question

I'm working with python3, and i'm trying to install " cairocffi " on Ubuntu. To do this, i've successfully installed:

1. python-dev
2. libffi-dev
3. cffi

But when i've trying to install "cairocffi" with pip install cairocffi ,I got:

      File "/usr/local/lib/python3.2/dist-packages/setuptools/dist.py", line 272
, in __init__
        _Distribution.__init__(self,attrs)
      File "/usr/lib/python3.2/distutils/dist.py", line 261, in __init__
        self.finalize_options()
      File "/usr/local/lib/python3.2/dist-packages/setuptools/dist.py", line 327
, in finalize_options
        ep.load()(self, ep.name, value)
      File "/usr/local/lib/python3.2/dist-packages/cffi/setuptools_ext.py", line

      File "/usr/local/lib/python3.2/dist-packages/cffi/setuptools_ext.py", line

        ffi.cdef(constants._CAIRO_HEADERS)
    AttributeError: 'module' object has no attribute '_CAIRO_HEADERS'

    Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-y0b_ir/cairocffi

Answer 1

通过安装特定版本的cairocffi（版本= 0.6）解决了我的问题

pip install cairocffi==0.6

Answer 2

I ran into this today as well. Are you working through the Real Python course?

Anyway, to fix the problem, I installed the python 3 version of python-dev:

sudo apt-get install python3-dev
sudo apt-get install libffi-dev
sudo pip3 install cffi
sudo pip3 install cairocffi

Hope this helps!

安装libffi-dev包可以解决这个问题，只需运行sudo apt install libffi-dev
