无法通过本地服务器 运行 Vega-Lite 可视化示例
Unable to run Vega-Lite visualization example through local server
我正在学习 Vega-Lite。
当我尝试运行一个简单的条形图示例时。浏览器控制台抛出错误:
我是运行宁this example
我正在使用 webstorm IDE;它创建了一个本地服务器,我通过它向浏览器提供网页。我也用 python http 服务器进行了测试。结果是一样的。
错误:
Failed to load resource: the server responded with a status of 404 ()
vega-embed@4:1 The input spec uses Vega-Lite v4, but the current version of Vega-Lite is vnot available.

解决方案:
更新脚本源解决了问题:
<script src="https://cdn.jsdelivr.net/npm/vega@5"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-lite@3"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-embed@4"></script>
编辑: 这是一个非常快速的变通方法,但不是一个合适的解决方案。 @tmori3y2 已经编写了正确的解决方案,并且文档也在 vega-lite 存储库上更新。
升级依赖项,不是 vega-embed@4 for vega-lite@4.0.0-beta.2
<script src="https://cdn.jsdelivr.net/npm/vega@5.6.0"></script>
<script src="https://cdn.jsdelivr.net/npm/vega-lite@4.0.0-beta.2"></script>
