我试着去做C:\Users\Admin\jekyll-gulp-sass-browser-sync-master\node_modules\gulp\node_modules\interpret\index.js这些改变:
var q = require('q');
至
var q = require('Q');
我跑了npm install -g但仍然没有.谁知道我为什么会这样?

我安装了 DOSBox 0.74、NASM(汇编程序)和 AFD(调试程序)。我安装驱动器并正确查看我的 .asm 文件。但是当我执行以下命令时:
nasm firstprogram.asm -o firstprogram.com
它给了我以下错误: This program cannot be run in dos mode
但是当我通过命令提示符 (cmd) 编译文件时,它编译正确,然后我必须去 DOSBox 运行 AFD 并调试 .com 文件。
知道为什么我会在 DOSBox 上收到此错误吗?
