在公司电脑上一步一步配置好的gulp正常运行没问题，然后我考U盘上带回来我自己的电脑，用
npm install
命令重新安装，总是报错，而且公司电脑配置好一个项目后再配置另外一个项目也会报错，等于同样的环境同样的操作就成功了一个项目，别的项目安装gulp-sass经常报错，非常诡异，求解，代码如下：

虽然提示所有包安装成功了，但是一执行gulp就会报如下错误：
E:\web\b2b>gulp
E:\web\b2b\node_modules\.npminstall\node-sass\3.4.2\node-sass\lib\extensions.j

Error: The `libsass` binding was not found in E:\web\b2b\node_modules\.npminst
all\node-sass\3.4.2\node-sass\vendor\win32-x64-46\binding.node
This usually happens because your node version has changed.
Run `npm rebuild node-sass` to build the binding for your current node version

我的package.json:
{
"name": "b2b",
"version": "1.0.0",
"description": "B2B",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"

"devDependencies": {
"gulp": "",

"gulp-clean-css": "",

"gulp-autoprefixer": "",
"browser-sync": "",
}
}错误提示里有建议你怎么做：
Run `npm rebuild node-sass` to build the binding for your current node version也就是在命令行里输入：
npm rebuild node-sass你公司电脑上的node.js版本比你家里的低，卸掉你家里的node.js,安装一个低版本的。
