Javascript &引用；TypeError:对象不是函数；

我不知道这是从哪里来的，安装了CO的4.0版和Node的0.11.14版。在3.1上运行的非常简单的代码（刚刚注意到以前版本的co是不同的）

给我这个输出：

/home/tbrown/.nvm/current/bin/node --debug-brk=23342 --nolazy
--harmony routes-to-apache-reverse-proxy.js Debugger listening on port 23342 THIS IS LOGGED /home/Documents/projects/server/routes/routes-to-apache-reverse-proxy.js:8 co(main)()

确定CO从3->4更改-这看起来是等效的

"use strict"
const co = require('co')

const main = function*() {
    console.log('THIS IS LOGGED')
}

co(main).
    catch(function(e){
        console.error(e)
    })

co(main)()

"use strict"
const co = require('co')

const main = function*() {
    console.log('THIS IS LOGGED')
}

co(main).
    catch(function(e){
        console.error(e)
    })
