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，它开始出现以下错误，甚至创建虚拟全局变量也无法像这里给出的那样工作 Angular 6 Auth0 - 全局未定义
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
错误如下:
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 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:
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)

然后继续下去.
推荐答案
在起始页中添加以下代码，例如index.html
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: []
};
示例:
<!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>
以上将适用于混合应用程序(在 Node 环境中)以及浏览器
Above will work on hybrid app (in Node environment) as well as in browser
对于未捕获的引用错误:全局未定义":
for "Uncaught ReferenceError: global is not defined":
var global = global || window;
对于未捕获的引用错误:缓冲区未定义":
for "Uncaught ReferenceError: Buffer is not defined":
var Buffer = Buffer || [];
对于未捕获的引用错误:进程未定义":
for "Uncaught ReferenceError: process is not defined":
var process = process || {
env: { DEBUG: undefined }
}
对于未捕获的类型错误:无法读取未定义的属性‘切片’":
for "Uncaught TypeError: Cannot read property 'slice' of undefined":
var process = process || {
env: { DEBUG: undefined },
version: []
};
