在开发 Next.js 项目。运行 npm run build 时，构建失败并出现以下错误：

Type error: Type '{ __tag__: "GET"; __param_position__: "second"; __param_type__: { params: { id: string; }; }; }' does not satisfy the constraint 'ParamCheck<RouteContext>'.
The types of '__param_type__.params' are incompatible between these types.
Type '{ id: string; }' is missing the following properties from type 'Promise<any>': then, catch, finally, [Symbol.toStringTag]

错误上下文： 导致问题的文件：app/api/projects/[id] 中的route.ts。 相关代码：这是似乎导致问题的 GET 处理程序的片段：

从“next/server”导入 { NextResponse }；

import {
    
     prisma } from "@/lib/prisma";

export async function GET(
  request: Request,
  {
     
      params }: {
     
      params: {
     
      id: string } }
) {
    
    
  try {
    
    
    const project = await prisma.project.findUnique({
    
    
      where: {
    
     id: params.id },
    });

    if (!project) {
    
    
      return NextResponse.json({
    
     error: "Project not found" }, {
    
     status: 404 });
    }

    return NextResponse.json(project);
  } catch (error) {
    
    
    console.error("Error fetching project:", error);
    return NextResponse.json({
    
     error: "Failed to fetch project" }, {
    
     status: 500 });
  }
}

如何修复

因为在 Next.js 15 中，params 是一个promise对象
以下是解决此问题的方法：

export async function GET(
  request: Request,
  params: {
     
      params: Promise<{
     
      id: string }> }
) {
    
    
  const id = await params.id
  // rest of your code
}
