Question

由于paramiko 2.0将其依赖性从pycrypto更改为加密，因此通过pip安装最新的Ansible失败。密码学依赖于cffi，这需要libffi-dev。有谁知道如何解决这一问题？（Ubuntu Trusty 14.04）

 angular
    .module('myMod')
    .factory('MyService');
MyService.$inject = ['$rootScope', 'atmosphereService', 'atmosphere'];

function MyService ($rootScope, atmosphere) {
    return {
        subscribe: subscribe,
        getMessage: getMessage
    };

    function subscribe (r) {
        var responseParameterDelegateFunctions = ['onOpen', 'onClientTimeout', 'onReopen', 'onMessage', 'onClose', 'onError'];
        var delegateFunctions = responseParameterDelegateFunctions;
        var result = {};

        delegateFunctions.push('onTransportFailure');
        delegateFunctions.push('onReconnect');

        angular.forEach(r, function (value, property) {
            if (typeof value === 'function' && delegateFunctions.indexOf(property) >= 0) {
                if (responseParameterDelegateFunctions.indexOf(property) >= 0)
                    **result[property] = function (response) {**
                        $rootScope.$apply(function () {
                            r[property](response);
                        });
                    };
                else if (property === 'onTransportFailure')
                    result.onTransportFailure = function (errorMsg, request) {
                        $rootScope.$apply(function () {
                            r.onTransportFailure(errorMsg, request);
                        });
                    };
                else if (property === 'onReconnect')
                    result.onReconnect = function (request, response) {
                        $rootScope.$apply(function () {
                            r.onReconnect(request, response);
                        });
                    };
            } else
                result[property] = r[property];
        });

        function getMessage () {
            var vm = this;
            var request = {
                url: '/chat',
                contentType: 'application/json',
                transport: 'websocket',
                reconnectInterval: 5000,
                enableXDR: true,
                timeout: 60000
            };

            request.onMessage(response); {
                vm.$apply (function () {
                    vm.model.message = atmosphere.util.parseJSON(response.responseBody);
                });
            }
        }
        return atmosphere.subscribe(result);
    }

}

})(window.angular);

要从pip安装cryptography >= 1.1，您需要安装libffi的开发人员包，因为它将包含缺少的头文件。由于您标记了Ubuntu，我假设您使用的是apt包管理器。

apt-get install libffi-dev

您还需要与ssl开发套件相同的发行版和gcc cryptography >= 1.1。如果您在系统环境中运行此操作，则几乎肯定已经安装了gcc，但如果缺少apt-get install libssl-dev，则可能还需要libffi-devel。

Fedora / RHEL等效项为openssl-devel和dnf，可以与yum或var app = require('express')(); var http = require('http').Server(app); var io = require('socket.io')(http); app.get('/', function(req, res){ res.sendFile(__dirname + '/index.html'); }); io.on('connection', function(socket){ console.log('a user connected'); socket.on('disconnect', function(){ console.log('user disconnected'); }); }); io.on('connection', function(socket){ socket.on('chat message', function(msg, usn){ io.emit('chat message', msg); io.emit('chat message', usn); }); }); http.listen(3000, function(){ console.log('listening on *:3000'); });一起安装，具体取决于您的操作系统和版本。

找到一个解决方案是安装每个的特定版本：

pip install paramiko==1.17.0 ansible==2.0.0.2

由于paramiko 2.0依赖项更改，Ansible 2.x安装失败
