错误正在显示这---〉'session.user'是可能的'undefined'.但是我可以访问值session.user.name但是为什么这错误我不能到execute npm run build now
Header.tsx

const { data: session } = useSession()

          ...

          <div 
              onClick={() => {!session? signIn(): signOut()}}
              className='items-center justify-center px-2 text- 
              white cursor-pointer hover:ring-1 hover:ring-white '>
               <p className='font-normal '>{!session ?   "sign in" 
               : `Hello ${session.user.name}`}</p>
                                 ^^^^^
               <h3 className='-mt-1 font-bold'>Account & Lists</h3>
            </div>

[下一页].js

import NextAuth from "next-auth"
import GoogleProvider from 'next-auth/providers/google'

export const authOptions = {
  providers: [
    // OAuth authentication providers...
    GoogleProvider({
      clientId: process.env.GOOGLE_ID,
      clientSecret: process.env.GOOGLE_SECRET,
      secret: process.env.NEXTAUTH_SECRET,
    })
  ]
}

export default NextAuth(authOptions)

next.js

{会话&&会话.用户？Hello ${session.user.name}：“登录”}
我解决了这个问题，这里我只需要检查session和session.user是否也为true
