升级到angular-6.x会出现“Uncaught ReferenceError：global is not defined”。 [英] Upgrading to angular-6.x gives "Uncaught ReferenceError: global is not defined"

问题描述

我将我的项目从angular-5.x升级到angular-6.x并且它开始给出以下错误，甚至创建虚拟全局变量也不起作用，如此处给出 Angular 6 Auth0 - 全局未定义

错误如下：

 未捕获的ReferenceError：未定义全局
 at Object ../ node_modules / has-binary2 / index.js （index.js：10）
 at __webpack_require__（bootstrap：81）
 at Object ../ node_modules / socket.io-parser / index.js（index.js：8）
 at __webpack_require__（bootstrap：81）
 at Object ../ node_modules / socket.io-client / lib / index.js（index.js：7）
 at __webpack_require__（bootstrap：81）
 at Object ../ src / app / app4pc / apiConnection / services / ApiConnectionServer.ts（auth.interceptor.ts：8）
 at __webpack_require__（bootstrap：81）
 at Object ../ src / app /app4pc/apiConnection/toServer.module.ts （ApiConnectionServer.ts:11）
 at __webpack_require__（bootstrap：81）
  

解决此问题后我收到以下错误：

 未捕获的ReferenceError：进程未定义
 at Object ../ node_modules / process-nextick -args / index.js（index.js：3）
 at __webpack_require__（bootstrap：81）
 at Object ../ node_modules / readable-stream / lib / _stream_readable.js（_stream_readable.js：26 ）

 at __webpack_require__（bootstrap：81）
 at Object ../ src / app /util/services/call.services.ts（notification.service.ts:12）
 at __webpack_require__（bootstrap：81）
  

并一直持续。

解决方案

在起始页面中添加以下代码，例如index.html

  var global = global ||窗口; 
 var Buffer = Buffer || []; 
 var process = process || {
 env：{DEBUG：undefined}，
 version：[] 
}; 
  

例如。如下：

 <！doctype html> 
< html lang =en> 
< head> 
< meta charset =utf-8> 
< title>客户< / title> 
< base href =/> 
< meta name =viewportcontent =width = device-width，initial-scale = 1> 
< link rel =icontype =image / x-iconhref =favicon.ico> 
< script> 
 var global = global ||窗口; 
 var Buffer = Buffer || []; 
 var process = process || {
 env：{DEBUG：undefined}，
 version：[] 
}; 
< / script> 
< / head> 
< body> 
< app-root> 
< div class =loader>< / div> 
< / app-root> 
< / body> 
< / html> 
  

以上将适用于混合应用程序（在节点环境中）以及浏览器中

• var global = global || window; // for Uncaught ReferenceError：global is not defined




• var Buffer = Buffer || []; //未捕获的ReferenceError：未定义缓冲区




• var process = process || {
env：{DEBUG：undefined}
} //对于Uncaught ReferenceError：进程未定义




• var process = process || {
env：{DEBUG：undefined}，
version：[]
}; // Uncaught TypeError：无法读取未定义的属性'slice'

I upgraded my project from angular-5.x to angular-6.x and it started giving the following error and even creation of dummy global variable does not work as given here Angular 6 Auth0 - global not defined

The error is as follows:

Uncaught ReferenceError: global is not defined
    at Object../node_modules/has-binary2/index.js (index.js:10)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/socket.io-parser/index.js (index.js:8)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/socket.io-client/lib/index.js (index.js:7)
    at __webpack_require__ (bootstrap:81)
    at Object../src/app/app4pc/apiConnection/services/ApiConnectionServer.ts (auth.interceptor.ts:8)
    at __webpack_require__ (bootstrap:81)
    at Object../src/app/app4pc/apiConnection/toServer.module.ts (ApiConnectionServer.ts:11)
    at __webpack_require__ (bootstrap:81)

after resolving this I get following error:

Uncaught ReferenceError: process is not defined
    at Object../node_modules/process-nextick-args/index.js (index.js:3)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/readable-stream/lib/_stream_readable.js (_stream_readable.js:26)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/readable-stream/readable-browser.js (readable-browser.js:1)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/simple-peer/index.js (index.js:7)
    at __webpack_require__ (bootstrap:81)
    at Object../src/app/util/services/call.services.ts (notification.service.ts:12)
    at __webpack_require__ (bootstrap:81)    

And continues on and on.

解决方案

Add following code in your starting page e.g. index.html

var global = global || window;
    var Buffer = Buffer || [];
    var process = process || {
      env: { DEBUG: undefined },
      version: []
    };

e.g. follows:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Client</title>
  <base href="/">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
  <script>
    var global = global || window;
    var Buffer = Buffer || [];
    var process = process || {
      env: { DEBUG: undefined },
      version: []
    };
  </script>
</head>
<body>
  <app-root>
    <div class="loader"></div>
  </app-root>
</body>
</html>

Above will work on hybrid app(in node environment) as well as in browser

• var global = global || window; // for Uncaught ReferenceError: global is not defined

• var Buffer = Buffer || []; // for Uncaught ReferenceError: Buffer is not defined

• var process = process || { env: { DEBUG: undefined } } // for Uncaught ReferenceError: process is not defined

• var process = process || { env: { DEBUG: undefined }, version: [] }; // Uncaught TypeError: Cannot read property 'slice' of undefined
