提问by ApathyBear
I am trying to use this npm modulewith browserify.
我正在尝试将此npm 模块与 browserify一起使用。
When I run $ browserify build/widget.js -o bundle.js, I recieve the following error:
当我运行时$ browserify build/widget.js -o bundle.js，我收到以下错误：

Note: the file build/widget.jsis not JSX, it has been built using the JSX compiler.
注意：该文件build/widget.js不是 JSX，它是使用JSX 编译器构建的。
Why would I be receiving unexpected token?
为什么我会收到意外的令牌？
Edit based on snozza's answer:
根据 snozza 的回答进行编辑：
I have installed npm install reactify --save.
我已经安装了npm install reactify --save.
Then I ran % browserify -t reactify build/widget.jsWhich gave the -bash: fg: %: no such job
然后我跑了% browserify -t reactify build/widget.js哪个给了-bash: fg: %: no such job
Then I tried browserify -t reactify build/widget.js, which gave:
然后我尝试了browserify -t reactify build/widget.js，它给出了：

Here is a snippet of my build/widget.jsas requested:
这是我build/widget.js的要求的片段：
var React =require('react');
var Spinner = require('react-spin')
var Loading = React.createClass({displayName: "Loading",
render: function() {
var spinCfg ={
lines: 5 // The number of lines to draw
, length: 5 // The length of each line
, width: 42 // The line thickness
, radius: 21 // The radius of the inner circle
, scale: 1 // Scales overall size of the spinner
, corners: 1 // Corner roundness (0..1)
, color: '#000' // #rgb or #rrggbb or array of colors
, opacity: 0.25 // Opacity of the lines
, rotate: 0 // The rotation offset
, direction: 1 // 1: clockwise, -1: counterclockwise
, speed: 1 // Rounds per second
, trail: 60 // Afterglow percentage
, fps: 20 // Frames per second when using setTimeout() as a fallback for CSS
, zIndex: 2e9 // The z-index (defaults to 2000000000)
, className: 'spinner' // The CSS class to assign to the spinner
, top: '50%' // Top position relative to parent
, left: '50%' // Left position relative to parent
, shadow: false // Whether to render a shadow
, hwaccel: false // Whether to use hardware acceleration
, position: 'absolute' // Element positioning
};
return React.createElement(Spinner, {config: spinCfg})
}
})
//...etc...
Any ideas?
有任何想法吗？

Looking through the main.js file of react-spin https://github.com/thomasboyt/react-spin/blob/master/src/main.js, it does indeed contain JSX syntax, namely:
查看 react-spin https://github.com/thomasboyt/react-spin/blob/master/src/main.js的 main.js 文件，确实包含 JSX 语法，即：
return (
<span ref="container" />
);
That is leading to the parse error when browserify is parsing that file. You could use a transformer such as https://www.npmjs.com/package/reactifyin conjunction with browserify to transform the JSX into vanilla JS.
当 browserify 解析该文件时，这会导致解析错误。您可以将转换器（例如https://www.npmjs.com/package/reactify）与 browserify 结合使用，将 JSX 转换为 vanilla JS。
EDIT: Reactify example
编辑：反应示例
As it is a required node_module that also needs to be transformed, you will need to add the browserify/reactify transform option to the package.json of react-spin. Go to the react-spinfolder and copy this into the package json, beneath "main":
由于它是必需的 node_module 也需要转换，因此您需要将 browserify/reactify 转换选项添加到 .json 的 package.json 中react-spin。转到react-spin文件夹并将其复制到包 json 中，在下面"main"：
"browserify": {"transform": ["reactify"]},
Then try run the browserify command once again
然后再次尝试运行 browserify 命令
