webpack alias一般用来配置路径别名，使我们可以少写路径代码：
chainWebpack: config => {
config.resolve.alias
.set(‘@‘, resolve(‘src‘))
.set(‘#‘, resolve(‘src/views/page1‘))
.set(‘&‘, resolve(‘src/views/page2‘));
},
具体操作如下：
src目录bug，注意里面引用其他的文件都需要写成绝对路径webpack aliasconst path = require(‘path‘);
module.exports = {
chainWebpack: config => {
config.resolve.alias
.set(‘./patchers‘, path.resolve(__dirname, ‘src/assets/patchers.js‘))
}
};
