browserfs - 无法在 BrowserFS 中创建文件夹

问题描述

我正在尝试遵循本指南：https ://github.com/pyodide/pyodide/issues/613

问题是我收到一条错误消息：

(index):181 Uncaught (in promise) TypeError: FS.createFolder is not a function

事实上，如果我尝试在控制台中打印 FS，我可以看到它包含很多功能，但 createFolder 不是其中之一：

我该如何解决这个问题？我需要创建一个文件夹，以便以后将文件夹中的所有文件导入我的程序。

提前致谢。

解决方案

出于某种原因，createFolderemscripten 中不存在 。改为使用createPath完全相同的参数。
