#解决办法
在执行first-network例子的上一层目录下面要有一个bin文件夹，里面放着需要的可执行文件。
操作：首先看一下，该目录下面是否有一个脚本：bootstrap-1.0.0.sh，有即执行即可。
没有的话： 你需要在fabric-samples目录下面执行如下命令，将所需要的二进制文件下载下来：
$ curl -sSL https://goo.gl/eYdRbX | bash
执行完以后会在fabric-samples目录下面创建一个bin目录，下面放着所需要的所有的二进制工具
注意：由于网络原因，以上的curl很可能执行失败，其实这个脚本文件其实在fabric中就已经存在了：
位置：gopath/src/github.com/hyperledger/fabric/scripts下面，直接将该脚本文件copy到fabric sample中就可以了
