Unable to determine Cesium base URL automatically (Typescript)

问题

I am trying to setup cesium and resium for react typescript and got stuck on the very initial steps. I am currently referencing steps from the following resium website, from here I have installed the packages and attempted to setup webpack based on the following steps. Based on the steps i installed the following package

npm install copy-webpack-plugin html-webpack-plugin html-webpack-include-assets-plugin
npm install cesium resium

The following example was also presented so i attempted to mimic the settings as much as possible creating and tweaking the following files in my root directory

webpack.config.js
package.json (Adding of scripts)

Once done I changed the following setting CESIUM_BASE_URL: JSON.stringify("/cesium") in webpack.config.js to point to my python server(https://localhost:5000) for the necessary tiles.

With this I expected the error to at least go away or maybe even stating another error such as "Asset XXX not found". But the error stating DeveloperError: Unable to determine Cesium base URL automatically, try defining a global variable called CESIUM_BASE_URL still persists.

I have also tried setting a variable for CESIUM_BASE_URL in env.local but it still doesn't work. Any pointers or guidance to any missing steps will be greatly appreciated.

回答1:

Add this script before others (or just before cesium) to your index.html

    ...
    </body>
    <script>
      window.CESIUM_BASE_URL = 'https://localhost:5000/';
    <script>
    <script>
    ...
