老师你好，

我已经完成全部课程并且发布到了npm。我现在想自己继续添加新的component，但是storybook遇到了syntax问题。下面是我的component的截图：

我尝试过以下方法：

1. 把泛形和props删除，storybook就可以运行了
2. 不删除泛形和props，storybook无法运行，但是我放到index.tsx里跑localhost是可以的

storybook给的错误提示是:

ERROR in ./src/components/Switch/switch.tsx
Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: /Users/yunwenzheng/repo/cereal-ui/src/components/Switch/switch.tsx: Unexpected token, expected "(" (30:10)
