用示例分析Vue-cli3生成的Vue項目如何加載Mxgraph

vue create [項目名]

cnpm install mxgraph --save

cnpm install exports-loader --save

cnpm install script-loader --save

const path = require('path');

function resolve(dir) {
  return path.join(__dirname, dir);
}

      .end();
    config.resolve.alias

      .set('@assets', resolve('src/assets'));
    // 按這種格式.set('', resolve('')) 自己添加
