安装“Cairocffi”失败

Question

我正在使用 python3，我正在尝试在 Ubuntu 上安装“cairocffi”。 为此，我已成功安装：

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

但是当我尝试使用pip install cairocffi 安装“cairocffi”时，我得到了：

      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
 161, in cffi_modules
        add_cffi_module(dist, cffi_module)
      File "/usr/local/lib/python3.2/dist-packages/cffi/setuptools_ext.py", line
 48, in add_cffi_module
        execfile(build_file_name, mod_vars)
      File "/usr/local/lib/python3.2/dist-packages/cffi/setuptools_ext.py", line
 24, in execfile
        exec(code, glob, glob)
      File "cairocffi/ffi_build.py", line 30, in <module>
        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

我今天也遇到了这个问题。您正在学习 Real Python 课程吗？

无论如何，为了解决这个问题，我安装了python 3版本的python-dev：

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

希望这会有所帮助！
