TSLint在TypeScript中的意外行为
TSLint在TypeScript中的意外行为
提问于 2020-01-27 14:35:37
我正在使用角形来构建一个项目，最近从VS代码切换到WebStorm，并且很难理解这一点。下面是一些我运行的测试，以确保一切正常。
我将test()函数的返回类型定义为string，但返回boolean，而不是抛出错误。然而，当我随机地写入一个未声明的变量时，它会抛出错误，它说期望赋值应该是未声明的变量。在它下面，我只调用测试函数，就像所以test()，只是看看它在调用函数时是否抛出了正确的错误；没有骰子。
以下是代码：
function test(): string {
return true;
}
bob;
bob = 1;
test();
这是我的TS.CONFIG：
{
"compileOnSave": false,
"compilerOptions": {
"baseUrl": "./",

],
"lib": [
"es2018",
"dom"
]
},
"angularCompilerOptions": {
"fullTemplateTypeCheck": true,
"strictInjectionParameters": true
}
}以下是TS.LINT：

}编辑：
TypeScript在这里根本不工作。我定义了一个参数，并将参数类型设置为string，然后传递给它一个整数，没有得到任何错误：

您需要保存该文件，以便它重新编译并抛出正确的错误。
