当我尝试 int integer = 1;
float floater =1.1111;
floater = integer;
时收到错误消息：
instanceof这是我的gemfile：
angular.module('so', []);
angular.module('so')
.factory('UserFac', function() {
function UserFac(first, last) {
//--------^-- give it the factory name
this.name = first + ' ' + last
//-^-- use the object created internally using this keyword
}
return UserFac;
})
.controller('UserCtrl', function(UserFac) {
var user = new UserFac('John', 'Doe');
console.log(user instanceof UserFac)
});
我的capfile
bundle exec cap production deploy --trace以及我的deploy.rb

在运行捆绑更新之后我刚才遇到了同样的错误，没有更新主要版本，除了Rake到11之外。从capistrano 3.2.1升级到3.4.0为我修复了它！
答案 1 :(得分：1)
我有同样的错误。
我的capistrano版本是3.1.0，rails版本是4.1.4。 但是我的同事没有这个问题。我尝试将红宝石版本，rvm版本更改为与同事的配置相同。它仍然无法正常工作。 因此，我尝试列出所有这些相关的宝石。我发现我的sshkit比他的高。
所以我将sshkit降级到1.7.1。
然后它起作用。
