Javascript Firebase/auth导入源地图警告

我正在使用firebase library v7.15.5构建react应用程序，当我导入“firebase/auth”时，它工作正常，但会在终端中向我发出警告：

这是文件的代码，我在其中初始化firebase模块：

import app from 'firebase/app';
import 'firebase/database';
import 'firebase/auth';

const config = {
  apiKey: process.env.API_KEY,
  authDomain: process.env.AUTH_DOMAIN,
  databaseURL: process.env.DB_URL,
  storageBucket: process.env.STORAGE_BUCKET,
};

app.initializeApp(config);

const database = app.database();
const auth = app.auth();

export { database, auth };

尝试删除节点_模块并重新安装所有模块，但无法解决问题。也许我应该以不同的方式导入它，或者配置webpack或tsconfig？我不知道

感谢您的帮助。

通过从webpack.config中删除这些代码行解决了此问题

{
    enforce: "pre",
    test: /\.js$/,
    loader: "source-map-loader"
  },

如果您绝对需要源映射（我认为您并不是真的需要，因为您的解决方案是禁用它们），那么您可以添加一个for firebase（或者只是firebase/auth）。示例（自行构建）：

注意：只使用上面的排除规则之一

那么，你刚刚禁用了源地图加载器？@Werlious是的，我想可能有另一种方法可以解决这个问题，但它对我有效

{
    enforce: "pre",
    test: /\.js$/,
    loader: "source-map-loader",
    exclude: /node_modules\/@firebase/ //to exclude firebase from source-map
    exclude: /node_modules\/@firebase\/auth/ //to just exclude firebase auth from source-map
  },
