linux - 安装 npm、nodejs - 使用 laravel gulp

Question

我正在使用 Linux。我正在尝试使用 Laravel 5.2 使用 gulp。我已经像这样安装了 nodejs:

sudo apt-get install nodejs

我还安装了 npm:

sudo apt-get install npm

我有他们两个的最新版本。但它不会在我的项目的根目录中创建文件夹 node_modules 。我已将它们链接起来 - 我已尝试检查:

sudo ln -s/usr/bin/nodejs/usr/bin/node
ln: 未能创建符号链接(symbolic link)‘/usr/bin/node’:文件存在


我的 packaage.json 文件是:

{
  "private": true,
  "scripts": {
    "prod": "gulp --production",
    "dev": "gulp watch"
  },
  "devDependencies": {
    "gulp": "^3.9.1",
    "laravel-elixir": "^5.0.0",
    "bootstrap-sass": "^3.0.0"
  }
}

Gulpfile.js 是:

var elixir = require('laravel-elixir');

/*
 |--------------------------------------------------------------------------
 | Elixir Asset Management
 |--------------------------------------------------------------------------
 |
 | Elixir provides a clean, fluent API for defining some basic Gulp tasks
 | for your Laravel application. By default, we are compiling the Sass
 | file for our application, as well as publishing vendor resources.
 |
 */

elixir(function(mix) {
    mix.sass('app.scss');
});

我的/resources/assets/css/app.scss 文件是:

 @import "node_modules/bootstrap-sass/assets/stylesheets/bootstrap";

.container {
	color: purple;
}
h1 {
	color:green;
}
body {
	background-color: red;
	font-size:10px;
}

在我的编辑器中有错误:无法解析导入 sass/scss 文件。因为我没有文件夹 node_modules。

如何让它发挥作用？我没做对什么？当我运行 gulp 时

谢谢!

听起来您没有在项目目录中运行 npm install。这样做会在项目目录中创建 Node 模块目录。

就像 mattferderer 在评论中建议的那样，只是不要执行 sudo 因为它会安装具有 sudo 权限的包，我认为你不会想要那样。 ;)

Laravel 会更喜欢本地版本的 gulp(如果你还安装了全局版本)。只是让您知道 bin 将隐藏在 $your_project_path/node_modules/.bin/gulp 中。再次确保您从存在 gulpfile.js 的项目目录运行它。

如果它仍然无法工作，我建议删除并清除 nodejs 并按照官方网站的说明重新安装它(有时简单的 sudo apt-get install nodejs npm 并且链接不会工作):https://nodejs.org/en/download/package-manager/
