Question

我的tsConfig.json如下：

{
    "compilerOptions": {
        "target":"es5",
        "module":"system",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "sourceMap": true,
        "moduleResolution": "node",
        "lib": [ "es2015", "dom" ]
    },
    "exclude": [
        "node_modules"
    ]
}

但是当我尝试运行时npm start它会抛出我的错误

TS5023：未知的编译器选项＆＃39; lib＆＃39;。

所以当我从tsConfig中删除lib时：

  {
        "compilerOptions": {
            "target":"es5",
            "module":"system",
            "emitDecoratorMetadata": true,
            "experimentalDecorators": true,
            "removeComments": false,
            "sourceMap": true,
            "moduleResolution": "node"
        },
        "exclude": [
            "node_modules"
        ]
    }

再次使用npm start

然后它开始抛出错误：

...

奇怪但配置：

{
    "compilerOptions": {
        "target":"es6",
        "module":"system",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "sourceMap": true,
        "moduleResolution": "node"
    },
    "exclude": [
        "node_modules"
    ]
}

对我来说超级好。

但是目标是es6;我无法为IE等旧版浏览器进行转换。

专家可以在这看看吗？可能是一个我不知道的小问题。

非常感谢任何帮助。
