当我瞄准es5时，如何将承诺与TypeScript结合使用？

我不熟悉这个编译器

lib

选项是什么，如果我要更改它，它会有什么影响

---

我正试图瞄准较老的浏览器，我认为需要支持

es5

。我想这可以通过传输/聚合填充来实现？我的类型脚本配置是：

TS2585: 'Promise' only refers to a type, but is being used as a value here. Do you need to change your target library? Try changing the `lib` compiler option to es2015 or later.

将以下内容添加到编译器选项中：

{
    "compilerOptions": {
        "sourceMap": true,
        "target": "es5",
        "declaration": true,
        "removeComments": false,
        "module" : "commonjs",
        "moduleResolution": "node",
        "resolveJsonModule": true,
    },
    "include": [
        "src/*"
    ],

    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

lib

选项的描述更为详细

解释

target

和

lib

之间的差异

也就是说，如果您可以接受使用

es6

，那么我认为您可以将

target

设置为

“es6”

，而不是混用

lib

，您可能应该添加类似@types/es6 promise的内容

{
    "compilerOptions": {
        "sourceMap": true,
        "target": "es5",
        "declaration": true,
        "removeComments": false,
        "module" : "commonjs",
        "moduleResolution": "node",
        "resolveJsonModule": true,
    },
    "include": [
        "src/*"
    ],

    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

"lib": [
        "dom",
        "es5",
        "es2015.promise"
    ]
