【ComfyUI】【Nunchaku】【diffusers报错解决】秋叶整合包安装 Nunchaku 报错的解决方法最近在折腾 AI 绘图时，我尝试在秋叶的 ComfyUI 整合包中安装 `ComfyUI-nunchaku` 插件（版本 0.3.3），结果启动后直接报错，提示无法从 `accelerate.utils.memory` 中导入 `clear_device_cache`，让我一度怀疑插件是否兼容。查阅了一堆 issue 和源码之后，总算找到了原因和解决方法。阅读详情

我现在刚开始学jacob，有些方法只是知道大概做什么用的，并不知道确切是怎么实现的，所以现在遇到问题很难搞定，虽然也有调试，但是调试没有发现问题，实际是不知道从哪里去分析程序出错的原因，就像楼上说的出错的原因是映射的问题，但是是什么映射？怎么映射的？现在项目很赶，但是我现在卡在这地方了，很郁闷~~

com.jacob.com.ComFailException: Can't map name to dispid: SaveAs

居然是映射的问题,楼主怎么找不出的,楼主应该多加调试,调试可以解决大部分问题.

谢谢楼上的哈，我改了一下程序，换了一下jacob的jar为1.15版本(jdk 1.5,tomcat 6.0)，卸掉office2007只用2003，现在上面的问题排除了，但是又出现了新的问题，我认真的检查了一下程序确实麽看出来哪里错，我把源码贴出来请大家帮我看看，谢谢先！

}

问题就出在这个方法：
public void saveAs(String outputFile)
{
Dispatch.call(doc, "SaveAs", outputFile);

}
异常信息：
com.jacob.com.ComFailException: Can't map name to dispid: SaveAs
