但是在浏览器中我什么也没看到，在控制台中显示此错误：
Failed to load resource: the server responded with a status of 404 (Not Found)
http://localhost:8200/build/ionlab/ionlab.z0nyl9ye.js
package =“ @ ionic / lab”：“ ^ 1.0.6”
如果我使用“离子服务”，一切都会很好。
也许我可以更改离子实验室的端口。
我在Ionic 4.0.5上使用Ionic Lab。
谢谢！
答案 0 :(得分：1)
要解决问题，请转到文件夹
Path_to_your_project\node_modules\@ionic\lab\www\build\ionlab
并将文件ionlab.925lkwi9.js重命名为ionlab.z0nyl9ye.js。
现在应该可以了。
