在离子2中运行离子服务时出现错误。

When I ran ionic serve in node.js command line or GitHub power shell, I encounter this error.

当我在node运行ionic服务时。js命令行或GitHub powershell，我遇到了这个错误。

There is an error in your gulpfile:
Error: `libsass` bindings not found. Try reinstalling `node-sass`?

Noted I could miss out node sass and gulp, and some windows user need visual studio, I follow this link How to compile or convert sass / scss to css with node-sass (no Ruby)? Using this command npm install --msvs_version=2013 gulp node-sass gulp-sass

注意，我可能会错过节点sass和gulp，而且有些windows用户需要visual studio，我遵循这个链接如何使用node-sass(没有Ruby)将sass / scss编译或转换为css ?使用此命令npm安装——msvs_version=2013 gulp节点-sass gulp

Now, I encounter this error.

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`?

2 个解决方案

#1

Check that you have the latest gulp-sass version in package.json; It's a dependency of node-sass + required by Ionic, e.g.

检查您在package.json中有最新的gulp-sass版本。它是node-sass +的一个依赖关系，如Ionic所要求的。

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

Uninstall gulp-sass

卸载gulp-sass

$ npm uninstall --save-dev gulp-sass

Reinstall gulp-sass

重新安装gulp-sass

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

There are a large number of issues pertaining to node-sass installation.
You may have to rebuild node-sass: $ npm rebuild node-sass

与节点sass安装相关的问题有很多。您可能需要重新构建节点:$ npm重新构建节点
