Sass编译器Phoenix框架

Question

我刚接触前端Phoenix框架，正在尝试实现Sass，但是“priv/static/css/app.css”不是使用“web/static/css/app.scss”编译的。我的app.css.map文件如下所示：

{"version":3,"sources":"web/static/css/app.scss","names":[],"mappings":"","file":"priv/static/css/app.css"}

我的brunch.config文件看起来像这样：

exports.config = {
  // See http://brunch.io/#documentation for docs.
  files: {
    scripts: {
      joinTo: "js/app.js"

      // To use a separate vendor.js bundle, specify two files path
      // https://github.com/brunch/brunch/blob/stable/docs/config.md#files
      // joinTo: {
      //  "js/app.js": /^(web\/static\/js)/,
      //  "js/vendor.js": /^(web\/static\/vendor)|(deps)/
      // }
      //
      // To change the order of concatenation of files, explicitly mention here
      // https://github.com/brunch/brunch/tree/master/docs#concatenation
      // order: {
      //   before: [
      //     "web/static/vendor/js/jquery-2.1.1.js",
      //     "web/static/vendor/js/bootstrap.min.js"
      //   ]
      // }
    },
    stylesheets: {
      joinTo: "css/app.css"
    },
    templates: {
      joinTo: "js/app.js"
    }
  },

  conventions: {
    // This option sets where we should place non-css and non-js assets in.
    // By default, we set this to "/web/static/assets". Files in this directory
    // will be copied to `paths.public`, which is "priv/static" by default.
    assets: /^(web\/static\/assets)/
  },

  // Phoenix paths configuration
  paths: {
    // Dependencies and current project directories to watch
    watched: [
      "web/static",
      "test/static"
    ],

    // Where to compile files to
    public: "priv/static"
  },

  // Configure your plugins
  plugins: {
    babel: {
      // Do not use ES6 compiler in vendor code
      ignore: [/web\/static\/vendor/]
    }
    sass: {
      options: {
        includePaths: ['web/static/vendor/bootstrap-sass/assets/stylesheets']
      }
    }
  },

  modules: {
    autoRequire: {
      "js/app.js": ["web/static/js/app"]
    }
  },

  npm: {
    enabled: true,
    // Whitelist the npm deps to be pulled in as front-end assets.
    // All other deps in package. will be excluded from the bundle.
    whitelist: ["phoenix", "phoenix_html"]
  }
};

当我运行node node_modules/brunch/bin/brunch build时，我也得到一个错误：

我是凤凰城的新手，如果我犯了一个愚蠢的错误，我很抱歉，任何建议都会很好，谢谢！

Answer 1

可能会检查您的文件/Users/dara.carolan/Sites/tomcat/node_modules/coffee-script/lib/coffee-script/register.js，它似乎是错误的:)

Answer 2

在Phoenix 1.4中， sass是使用、webpack、实现的，如here所解释的那样。

在您的npm中安装node-sass和sass-loader {test: /\.scss$/, use: [ MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader' ]}

• Rename

• project

• Update {test: /\.scss$/, use: [ MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader' ]}

• Rename app.js to import css from "../css/app.scss"

：{test: /\.scss$/, use: [ MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader' ]}

• Rename app.css to app.scss

• Update in app.jstoimport css from "../css/app.scss"
