错误5条

const storageRef = ref（storage，files/${req.file.originalname +““+ dateTime}）;” const metadata = { contentType：}; document. writeln;”
const snapshot = await uploadBytesResumable（storageRef，req.file.buffer，metadata）;”name：req.file.originalname， type：req.file.mimetype，`

我安装了一些包，如：

npm i @types/express
npm install dotenv
npm i @types/multer --save-dev
npm install typescript
但还是不起作用。。
