Ivy和CASL的构建问题

Question

我已经尝试安装CASL在我的项目中的角。不幸的是，当我试图启动应用程序时，我会收到以下错误消息：

ERROR in /Users/julien/Documents/repositories/frontend/node_modules/@casl/angular/__ivy_ngcc__/dist/es6/index.js

我正在使用最新版本的角"10.0.9“。如果我完全禁用源映射，那么消息就会消失，但在开发过程中它并不是一个真正的选项。

有什么想法吗？

Answer 1

这是@casl/a中的一个bug，源代码映射的生成是在@casl/角@4.1.5中固定的。

现在，它按预期工作。
