【问题描述】:
使用 aurelia-cli - SystemJS bundler 选项创建了一个新项目。
从 npm 安装了 htmlparser2 模块,该模块具有 buffer.js 作为依赖项。
尝试导入 htmlparser2 时出现以下错误:
bluebird.core.js:3434 Error: global is not defined
Evaluating http://localhost:9000/buffer/index
在检查 vendor-bundle -> 这是产生错误的行:
Buffer.TYPED_ARRAY_SUPPORT = global.TYPED_ARRAY_SUPPORT !== undefined
? global.TYPED_ARRAY_SUPPORT
: typedArraySupport()
用angualar-cli找到了similar issue,解决方法是手动打开节点全局
Node global is turned off. It works fine if I manually turn it on again.
问题是如何使用 aurelia-cli 做到这一点?有什么建议吗?

/**
* If `Buffer.TYPED_ARRAY_SUPPORT`:
* === true Use Uint8Array implementation (fastest)
* === false Use Object implementation (most compatible, even IE6)
*
* Browsers that support typed arrays are IE 10+, Firefox 4+, Chrome 7+, Safari 5.1+,
* Opera 11.6+, iOS 4.2+.
*
* Due to various browser bugs, sometimes the Object implementation will be used even
* when the browser supports typed arrays.
*
* Note:
*
* - Firefox 4-29 lacks support for adding new properties to `Uint8Array` instances,
* See: https://bugzilla.mozilla.org/show_bug.cgi?id=695438.
*
* - Chrome 9-10 is missing the `TypedArray.prototype.subarray` function.
*
* - IE10 has a broken `TypedArray.prototype.subarray` function which returns arrays of
* incorrect length in some situations.
* We detect these buggy browsers and set `Buffer.TYPED_ARRAY_SUPPORT` to `false` so they
* get the Object implementation, which is slower but behaves correctly.
