javascript - 未捕获的类型错误 : Cannot read property 'BlobBuilder' of undefined

Question

我正在使用 Socket.IO 在 RethinkDB 和 React 之间来回传输信息。我不断得到

Uncaught TypeError: Cannot read property 'BlobBuilder' of undefined

whenever I try to run the file and, after some sleuthing, I was able to figure out that it came from my socket listener files. Here's one for an example:

// ./socket-listeners/inventory-listener.js
// imported into index.jsx

import io from 'socket.io-client';
const socket = io.connect('/');

const InventorySocketListener = (store) => {
    socket.on('item:insert', (item) => {
        store.dispatch({
            type: 'item:insert',
            item
        });
    });

    socket.on('item:update', (item) => {
        store.dispatch({
            type: 'item:update',
            item
        });
    });

    socket.on('item:delete', (item) => {
        store.dispatch({
            type: 'item:delete',
            item
        });
    });
};

export default InventorySocketListener;

如您所见，我在那里没有 BlobBuilder，而且我自己的搜索告诉我它已被弃用 (MDN)。我也确保更新了我的所有 npm 包。然而，在我的一生中，我无法弄清楚这到底是从哪里来的，也不知道如何解决它。想法？谢谢!

我对此进行了研究，结果发现问题最终出在“socket.io-client”的导入方式上。修复最终是import io from 'socket.io-client/dist/socket.io';。
