如何安装cairocffi到pip？如何pip安装cairocffi？

cairocffi是基于CFFI的嵌入式替代品Pycairohttps://github.com/SimonSapin/cairocffi。

我试图在Ubuntu 14.04安装：

[email protected]:~$ cat /etc/*-release 
DISTRIB_ID=Ubuntu 
DISTRIB_RELEASE=14.04 
DISTRIB_CODENAME=trusty 
DISTRIB_DESCRIPTION="Ubuntu 14.04.2 LTS"

我试着用标准PIP命令安装，但我得到这个：

$ sudo pip install cairocffi

我手动检查许可，我意识到没有写访问权限。 这是为什么？为什么sudo不能覆盖权限呢？

由于@MattDMo的建议，我已经试过apt-get install libffi但它仍然没有解决：

[email protected]:~$ sudo apt-get install libffi libffi-dev 
Reading package lists... Done 
Building dependency tree  
Reading state information... Done 
E: Unable to locate package libffi

但包管理器上没有任何libffi，所以我试过libffi-dev：

[email protected]:~$ sudo apt-get install libffi-dev

正如我所说的，你需要使用你的Linux发行包管理器（'yum'，'apt-get'，无论）来安装系统包'libffi'和'libffi-dev'。对不起，如果不是很清楚。 – MattDMo

此外，下次您有关于答案的问题或疑问时，您是否可以在答案下面发表评论，而不仅仅是编辑问题，即使它只是指向编辑？我只看到这个，因为我不小心将标签打开。评论会向作者发送通知，以及您可能会提及的任何人。 – MattDMo

这是正确的错误消息：

No package 'libffi' found

您需要安装libffi和libffi-dev通过您的发行包管理器（yum，apt-get，无论）在安装pip之前都会起作用。他们的名字可能会从平台到平台很小。

@alvas你使用什么发行版和版本？ – MattDMo

这是Ubuntu 14.04 – alvas

在Ubuntu上，软件包是['libffi6']（http://packages.ubuntu.com/trusty/libffi6）和[''libffi-dev']]（http://packages.ubuntu.com/trusty/libffi-dev的）。运行'sudo apt-get install libffi6 libffi-dev'应该可以正常工作... – MattDMo

对我而言，在Windows 10上使用python 3.5.3rc1，pip install cairocffi失败。做pip install cffi足以让它成功。
