npm安装依赖后报错

今天npm安装依赖后报错

 error  in ./node_modules/shpjs/lib/index.js

Module parse failed: Unexpected token (129:39)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

是因为无法识别 ?. 语法，导致报错Module parse failed: Unexpected token

解决：

在vue.config.js 里面加上 transpileDependencies: ['ol', "color-parse", 'ol/renderer/webgl', 'shpjs'],

哪个包报错就加上哪个包
