typescript - TypeScript 接口没有按预期工作，当提供的类型错误时它不会抛出任何“警告”

Question

TypeScript 界面无法按预期使用“*.vue”文件。当提供的类型不好时，它不会抛出任何“警告”。示例表单 vue.js 文件：

<script lang="ts">

interface Test {
   w: string;
   h: number;
}

// This part of code doesn't work. 
// It doesn't show any message about 
// type incompatibility 
//(propert h must have "number" type).

let myVar: Test = {
    w: "10",
    h: "26",
};

//At the same time this code works correctly in '.ts' files.

</script>

如何解决？
