由于css中的svg，无法使用vue cli 3模板构建项目

Question

在移动到vue-cli 3时，我遇到了以下问题。我将插件的css导入到我的app.scss。

这一行：background-image: url(default-skin.svg);破坏了yarn build，后者抛出了这个错误：

Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
ReferenceError: navigator is not defined

这是我的vue.config.js：

const path = require('path')
const webpack = require('webpack')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const SpriteLoaderPlugin = require('svg-sprite-loader/plugin')

const ASSETS_DIR = 'static'

module.exports = {
  assetsDir: ASSETS_DIR,
  runtimeCompiler: true,
  chainWebpack: config => {
    config
      .plugin('provide-plugin')
        .use(webpack.ProvidePlugin, [{
          axios: "axios",
          $: "jquery",
          jQuery: "jquery",
          _: "lodash",
          mapGetters: ['vuex', 'mapGetters'],
          mapActions: ['vuex', 'mapActions']
        }])
        .end()
      .plugin('copy-plugin')
        .use(CopyWebpackPlugin, [
          [{
            from: path.resolve(__dirname, 'static'),
            to: ASSETS_DIR,
            ignore: ['.*']
          }]
        ])
        .end()
      .plugin('sprite-loader-plugin')
        .use(SpriteLoaderPlugin)

    config.module
      .rule('svg')
        .test(/\.svg$/)
        .use('file-loader')
          .loader('svg-sprite-loader')
  }
}

有解决办法吗？

Answer 1

我没有解决办法，也没有充分的解释，但有个解决办法.

这个问题似乎是由postcss-import在从证监会的<style>标记中导入CSS文件时引起的：

// App.vue
<style lang="scss">
  @import 'app.scss'; /* imports default.css -> default-skin.svg */
</style>

您可以通过将导入移至<script>标记(或移至main.js)来解决构建错误：

// App.vue
<script>
  import 'app.scss'; /* imports default.css -> default-skin.svg */
</script>

Answer 2

尝试删除节点模块文件夹，然后再运行纱线安装。

如果不起作用，试着：

global.navigator = {
  userAgent: 'node.js'
};

Answer 3

参考vue-pswipe，GuoQichen为svg使用此配置。

config.module
  .rule('svg')
  .use('file-loader')
  .clear()
  .loader('url-loader')
  .options({
    limit: 4 * 1024,
    name: 'img/[name].[hash:8].[ext]',
  })
