Ecmascript 6 添加expect库时出错(https://github.com/mjackson/expect)在JSBin.com上,ecmascript-6,jsbin,Ecmascript 6,Jsbin,在Jsbin.com控制台中尝试添加Expect库时，它返回undefined var mylib = { text: 'My Category', scripts: [ { text: 'My library', url: 'https://github.com/mjackson/expect/blob/master/modules/index.js' } ] }; libraries.add(mylib); 为什么不在头部添加脚本标记呢。在jsbin.com中试试这个

在Jsbin.com控制台中尝试添加Expect库时，它返回undefined

var mylib = {
  text: 'My Category',
  scripts: [
    { text: 'My library', url: 'https://github.com/mjackson/expect/blob/master/modules/index.js' }
  ]
};
libraries.add(mylib);
为什么不在头部添加脚本标记呢。在jsbin.com中试试这个

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JS Bin</title>
  <script src="https://unpkg.com/expect@%3C21/umd/expect.min.js"></script>
</head>

  <script>
    console.log("expect", expect.createSpy)
  </script>

</html> 


JS-Bin
log（“expect”，expect.createSpy）
您可以使用此独立模块：

<script src="https://wzrd.in/standalone/expect@22.4.3"></script>
将它放在HTML文件的
头
标记中
