Error: TypeScript emitted no output for

ERROR in ./src/index.tsx
Module build failed (from ./node_modules/ts-loader/index.js):
Error: TypeScript emitted no output for C:\Users\tenrzzhang\Desktop\ten\reactapp\src\index.tsx.

解决：

修改tsconfig.json文件：

"noEmit": false  // 不生成输出文件

改为false，则执行build时不会报错
