为什么我的 webpack 在编译 .sass 文件时会尝试加载 .js 文件? [英] Why is my webpack trying to load .js files when compiling a .sass file?

问题描述

我正在尝试使用 blueprintjs，所以我遵循了这一行的教程:

I'm trying to use blueprintjs so I followed the tutorial with this line:

main.sass

@import "~@blueprintjs/core";

但是我的 webpack-dev-server 给了我这个错误日志:

However my webpack-dev-server gives me this error log:

ERROR in ./node_modules/css-loader?{"minimize":false}!./node_modules/postcss-loader/lib?{"sourceMap":true}!./node_modules/resolve-url-loader!./node_modules/sass-loader/lib/loader.js?{"sourceMap":true}!./app/javascript/packs/main.sass
Module build failed:
 */
  ^
      Invalid CSS after " */": expected 1 selector or at-rule, was '"use strict";'
      in <redacted>/node_modules/@blueprintjs/core/dist/index.js (line 6, column 4)
webpack: Failed to compile.

所以我很困惑为什么它试图将 index.js 文件作为 sass 解析为 css！

So I'm confused why it's trying to parse an index.js file as sass into css!

看./config/webpack/loaders/sass.js，我没碰过:

const ExtractTextPlugin = require('extract-text-webpack-plugin')
const { env } = require('../configuration.js')

module.exports = {
  test: /\.(scss|sass|css)$/i,
  use: ExtractTextPlugin.extract({
    fallback: 'style-loader',
    use: [
      { loader: 'css-loader', options: { minimize: env.NODE_ENV === 'production' } },
      { loader: 'postcss-loader', options: { sourceMap: true } },
      'resolve-url-loader',
      { loader: 'sass-loader', options: { sourceMap: true } }
    ]
  })
}

我只看到它试图读取 sass、scss 和 css 文件.有什么我遗漏或应该检查的想法吗?

I only see it trying to read sass, scss and css files. Any ideas what I'm missing or should check?

推荐答案

您收到一个错误，因为在您的 main.sass 文件中您正在导入一个 JS 模块.~@blueprintjs/core 解析为 node_modules/@blueprintjs/core/dist/index.js，因此您在此过程中混合了 JS.

You are receiving an error because in you main.sass file you are importing a JS module. ~@blueprintjs/core resolves to node_modules/@blueprintjs/core/dist/index.js and thus you are getting JS mixed in the process.

您应该看到 blueprintjs/core/dist 文件夹包含哪些文件，并且只导入 sass/scss/css 文件以进行构建.

You should see what files the blueprintjs/core/dist folder contains and only import sass/scss/css files to make your build.
