AssertionError [ERR_ASSERTION]: chunk of umi not found.

这个错误通常是在使用 Node.js 的内置模块 assert 断言时发生的。它表示断言失败，并且断言的表达式的值不为真。

在你的情况下，错误信息 "chunk of umi not found" 可能是由于在读取文件时未找到指定的数据块引起的。你可以检查一下你的代码，看看是哪个操作导致了这个错误。另外，也可以尝试使用调试工具来帮助你定位问题。

AssertionError [ERR_ASSERTION]: Invalid callback object specified.

This error occurs when a function that expects a callback is called with an invalid callback object. A callback is a function that is passed as an argument to another function and is executed when the main function completes its operation.

To resolve this error, you should check that the callback function is defined and has the correct syntax. You should also verify that the function that is calling the callback is passing the correct arguments.

Example:

function fetchData(callback) {
  if (typeof callback === 'function') {
    callback(null, data);
  } else {
    throw new AssertionError('Invalid callback object specified.');
  }
}

// Correct syntax for callback function
function myCallbackFunction(error, data) {
  if (error) {
    console.log(error);
  } else {
    console.log(data);
  }
}

// Call the fetchData function with a valid callback object
fetchData(myCallbackFunction);

// Call the fetchData function with an invalid callback object
fetchData('not a function');

In the above example, the `fetchData` function expects a callback function to be passed as an argument. If the callback is not a function, an `AssertionError` is thrown with the message "Invalid callback object specified."

error - Can not resolve dependence : 'classnames', please install it error - AssertionError [ERR_ASSERTION]: dependence not found: classnames

这错误提示是因为在你所运行的代码中，缺少一个名为 "classnames" 的依赖项。你可以通过以下命令来安装该依赖项：

npm install classnames

或者如果你使用的是 yarn，可以运行以下命令：

yarn add classnames

安装完成后，你就可以在你的代码中使用 "classnames" 依赖项了。
