Question

当我在node.js命令行或GitHub power shell中运行离子服务时，我遇到了这个错误。

There is an error in your gulpfile:
Error: `libsass` bindings not found. Try reinstalling `node-sass`?
    at getBinding (D:\GitHub\stockMarketApp\node_modules\gulp-sass\node_modules\node-sass\lib\index.js:22:11)
    at Object.<anonymous> (D:\GitHub\stockMarketApp\node_modules\gulp-sass\node_modules\node-sass\lib\index.js:188:23)

注意我可能错过了节点sass和gulp，而且有些windows用户需要visual studio，我按照这个链接How to compile or convert sass / scss to css with node-sass (no Ruby)? 使用此命令npm install --msvs_version=2013 gulp node-sass gulp-sass

现在，我遇到了这个错误。

D:\GitHub\stockMarketApp [master ≡ +245 ~0 -5054 !]>  ionic serve
Uh oh! Looks like you're missing a module in your gulpfile:
Cannot find module 'vinyl'

Do you need to run `npm install`?

我起诉的所有版本如下：

D:\GitHub\stockMarketApp [master ≡ +245 ~0 -5054 !]>  npm -v
3.9.0
D:\GitHub\stockMarketApp [master ≡ +245 ~0 -5054 !]>  node -v

Answer 1

检查gulp-sass中是否有最新的package.json版本;它是Ionic所需的node-sass +的依赖，例如

"dependencies": {
    "gulp-sass": "^2.3.2"
  },

卸载gulp-sass

$ npm uninstall --save-dev gulp-sass

重新安装gulp-sass

$ npm install --save-dev gulp-sass@2

有很多与node-sass安装有关的问题您可能必须重建node-sass：$ npm rebuild node-sass

Answer 2

这个解决方案对我有用：

Uninstall gulp-sass                
 $ npm uninstall --save-dev gulp-sass
Reinstall gulp-sass
 $ npm install --save-dev gulp-sass@2

 $ npm install bower
 $ionic serve --lab

在Ionic 2中运行Ionic服务时出错
