模块解析失败：意外字符“#”

Question

我正在 Cloud9 上构建一个 React 项目，当我在终端中输入“npm start”时，我收到如下错误消息：

./node_modules/fetch-blob/index.js 47:2
Module parse failed: Unexpected character '#' (47:2)
File was processed with these loaders:
 * ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
| const _Blob = class Blob {
|   /** @type {Array.<(Blob|Uint8Array)>} */
>   #parts = [];
|   #type = '';
|   #size = 0;

这与“节点获取”有关吗？直到我安装了“node-fetch”并使用它后，我才遇到该错误。
