typescript报错指向js而不是ts

Question

Cannot read property 'a' of undefined

TypeError: Cannot read property 'a' of undefined
    at Routes.index (/home/huo/zmwork/yuedun_ts/build/routes/index.js:13:44)
    ……

tsconfig.json配置：

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "noImplicitAny": false,
        "noImplicitReturns": true,
        "noFallthroughCasesInSwitch": true,
        "experimentalDecorators": true,
        "noEmitOnError": true,
        "removeComments": true,
        "allowUnreachableCode": true,
        "noImplicitUseStrict": true,
        "diagnostics":false,
        "pretty": true,
        "sourceRoot": "./",
        "rootDir": "./",
        "outDir": "./build",
        "mapRoot": "./build",
        "sourceMap": true
    },
    "include": [
        "./**/*.ts"
    ]
}

生成的map文件：

{"version":3,"file":"index.js","sourceRoot":"/home/huo/zmwork/yuedun_ts/","sources":["routes/index.ts"],"names":[],"mappings":";;;;;;

该配置的都配置了，可以断点调试，但是报错文件却是js文件
