问题
I'm using Mapbox, and I'm trying to convert a Geojson to a zipped shapefile using shp-write. But when I follow the example given on the GitHub page, I'm getting a "ReferenceError: require is not defined" error on this line:
var shpwrite = require('shp-write');
This is a jsfiddle in which you can test this. I'm relatively new to JavaScript, and haven't had to use the 'require()' function before.
回答1:
The jsfiddle you provided includes several external resources, among which a shpwrite delivered by unpkg that you may be missing.
Usually require doesn't exist in your browser. You would need to execute it with Node.js or use a module bundler like Webpack, but Unpkg takes care of it for you.
So adding:
<script src="https://unpkg.com/shp-write@latest/shpwrite.js"></script>
on your page should make it work.
