Question

我在React Next上使用openlayers库。通过npm添加openlayers库。但是，当我导入“从'ol / Map'中导入地图”库时，出现以下错误。

import PluggableMap from './PluggableMap.js';
       ^^^^^^^^^^^^

在next.config.js和.babelrc文件中我什么也没做。如何解决该错误？

注意：Openlayers与经典的React一起工作。

似乎ol在服务器端不起作用，因为它需要窗口之类的东西，因此您需要这样做

componentDidMount() {
   const map = require("ol/Map").default;
}

React Next的Openlayers编译错误
