我遇到了与您相同的问题，并且解决了. 您可以按照以下步骤操作:
I faced the issue same as you and I resolved. You can follow these steps:
- 将此文件添加到根目录
patch.js
const fs = require('fs');
const f = 'node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js';
fs.readFile(f, 'utf8', function (err,data) {
if (err) {
return console.log(err);
}
var result = data.replace(/node: false/g, 'node: {crypto: true, stream: true}');
fs.writeFile(f, result, 'utf8', function (err) {
if (err) return console.log(err);
});
});
- 将此命令添加到 package.json 文件
package.json
{...
"scripts": {
"postinstall": "node patch.js",
...
}
}
