React项目中Shadcn+Tailwind按钮组件不显示问题求助

跟随YouTube教程，使用shadcn + Tailwind + React构建项目，尝试渲染按钮组件时发现组件无法显示。

此前曾遇路径问题，通过以下步骤解决：

• 删除@文件夹
• 执行命令：npm install --save-dev vite-tsconfig-paths
• 在vite.config中配置路径插件：

// ...
import tsconfigPaths from 'vite-tsconfig-paths';

export default defineConfig({
  plugins: [tsconfigPaths()],
});

路径问题解决后，按钮组件仍无法显示。仅修改过上述配置代码及AuthLayout.tsx文件，相关代码如下：

AuthLayout.tsx #

import { Outlet , Navigate } from 'react-router-dom';

const AuthLayout = () => {
  const isAuthenticated = false; 
  return (
    <>
     {isAuthenticated ? (
      <Navigate to= "/" />
     ): (
      <>
        <section className= "flex flex-1 justify-center items-center flex-col py-10">
          <Outlet/>
        </section>
      </>
     )}
    </>
  )
}

export default AuthLayout

button.tsx（按钮组件文件） #

import * as React from "react"
import { Slot } from "@radix-ui/react-slot"
import { cva, type VariantProps } from "class-variance-authority"

import { cn } from "src/lib/utils"

const buttonVariants = cva(
  "inline-flex items-center justify-center whitespace-nowrap rounded-md text-sm font-medium ring-offset-background transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:pointer-events-none disabled:opacity-50",
  {
    variants: {
      variant: {
        default: "bg-primary text-primary-foreground hover:bg-primary/90",
        destructive:
          "bg-destructive text-destructive-foreground hover:bg-destructive/90",
        outline:
          "border border-input bg-background hover:bg-accent hover:text-accent-foreground",
        secondary:
          "bg-secondary text-secondary-foreground hover:bg-secondary/80",
        ghost: "hover:bg-accent hover:text-accent-foreground",
        link: "text-primary underline-offset-4 hover:underline",
      },
      size: {
        default: "h-10 px-4 py-2",
        sm: "h-9 rounded-md px-3",
        lg: "h-11 rounded-md px-8",
        icon: "h-10 w-10",
      },
    },
    defaultVariants: {
      variant: "default",
      size: "default",
    },
  }
)

export interface ButtonProps
  extends React.ButtonHTMLAttributes<HTMLButtonElement>,
    VariantProps<typeof buttonVariants> {
  asChild?: boolean
}

const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, variant, size, asChild = false, ...props }, ref) => {
    const Comp = asChild ? Slot : "button"
    return (
      <Comp
        className={cn(buttonVariants({ variant, size, className }))}
        ref={ref}
        {...props}
      />
    )
  }
)
Button.displayName = "Button"

export { Button, buttonVariants }

SignupForm.tsx（尝试渲染按钮的组件） #

import { Button } from "src/components/ui/button"

const SignupForm = () => {
  return (
    <div>
      <Button>Click me</Button>
    </div>
  )
}

export default SignupForm

严格按照教程步骤操作，推测仍存在未发现的路径问题，所有更新文件已上传至GitHub仓库。
