npm link后，執(zhí)行命令，提示：no such file or directory

測(cè)試命令行工具，依照一些demo，但是完成后，執(zhí)行卻提示：no such file or directory，網(wǎng)上的一些例子都沒(méi)有這樣的提示

{
  "name": "node-commander",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "bin": {
      "hello": "hello.js"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

hello.js

#! /user/bin/env node

'use strict';
console.log('--- hello world ---');

執(zhí)行 npm link,應(yīng)該是沒(méi)有成功，為什么了？

npm WARN node-commander@1.0.0 No description
npm WARN node-commander@1.0.0 No repository field.
/usr/local/bin/hello -> /usr/local/lib/node_modules/node-commander/hello.js
/usr/local/lib/node_modules/node-commander -> /Users/xuzhiqiang/Desktop/code/node-commander

執(zhí)行：hello

zsh: /usr/local/bin/hello: bad interpreter: /user/bin/env: no such file or directory

請(qǐng)教大神們
