Gulp没有将scss转换为css

Question

在Visual Studio中,Gulp未运行以将我的scss文件转换为css.

我得到的错误是:

cmd.exe/c gulp --tasks-simple C:\ Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject \node_modules \node-sass\lib\binding.js:15 throw new Error(errors.missingBinary ()); ^错误:缺少绑定C:\ Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject \node_modules \node-sass\vendor\win32-x64-47\binding.node Node Sass找不到绑定当前环境:带有Node.js 5.x的Windows 64位找到以下环境的绑定: - 带有Node.js 7.x的Windows 64位这通常是因为您的环境自运行以来已更改npm install.运行npm rebuild node-sass以构建当前环境的绑定.

我确实npm rebuild node-sass在我的项目文件夹的根目录中运行但仍然遇到了同样的错误.这是我跑完后得到的npm rebuild node-sass:

二进制文件位于C:\ Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject \node_modules \node-sass\vendor\win32-x64-51\binding.node测试二进制二进制文件很好node-sass@3.13. 1 C:\ Users\sam\Documents\Visual Studio 2017\Projects\MyProject\MyProject \node_modules \node-sass

我Gulpfile.js看起来像这样:

var gulp = require('gulp'),
    sass = require("gulp-sass");;

gulp.task('default', function () {
    // place code for your default task here
});

gulp.task("sass", function () {
    return gulp.src('wwwroot/scss/style.scss')
      .pipe(sass())
      .pipe(gulp.dest('wwwroot/css'));
});

知道如何解决这个问题吗？

更新:如果我node -v在命令行中运行,我得到v7.10.0.

此外,我发现这篇文章并按照说明进行操作,但问题仍然没有解决,我现在也在我的项目中看到了Bower的问题.这是文章:https: //ryanhayes.net/synchronize-node-js-install-version-with-visual-studio-2015/

这就是我在项目中看到的内容:

如果我在Visual Studio中单击"管理Bower软件包",它只是尝试并尝试但似乎无法找到已安装的软件包.

更新2:

这是`package.json':

Answer 1

cnpm install gulp-load-plugins --save-dev

然后修改gulpfile

var gulp = require('gulp'),
    sass = require("gulp-sass"),
    gulpLoadPlugins = require('gulp-load-plugins'),
    $ = gulpLoadPlugins();

gulp.task('default', function () {
    // place code for your default task here
});

gulp.task("sass", function () {
    return gulp.src('wwwroot/scss/style.scss')
      .pipe($.sass())
      .pipe(gulp.dest('wwwroot/css'));
});
