解决Next.js14在GitHub Pages部署的关键问题

👋这次在github page部署Next.js项目时，碰上了不少的问题，但是很多问题在查阅过程中发现缺乏完整的解决办法，或者解决办法不是很好，记录一下最后自己是怎么解决的。

vbnet 复制代码

PS：NEXT.JS的版本是14～

第一个报错: The "next export" command has been removed in favor of "output: export" in next.config.js

github actions提示是在Static HTML export with Next.js 阶段报错了，这时候我们查阅官网，发现next14导出静态资源时，不需要执行next export，而是修改next.config.js即可

lua 复制代码

//next.config.js
/**
 * @type {import('next').NextConfig}
 */
const nextConfig = {
  output: 'export',
}
 
module.exports = nextConfig

因此可以在yml文件里删除以下两行代码：

vbnet 复制代码

- name: Static HTML export with Next.js
  run: ${{ steps.detect-package-manager.outputs.runner }} next export

问题二：部署成功后，页面"白纸黑字"，静态资源加载失败

在actions终于不报错后，我兴奋地打开了部署后的页面，发现只能看到"白纸黑字"，发现静态资源没有加载出来。打开F12后发现请求的资源地址为 xxx.github.io/_next/stati... 直接去访问了我github仓库的根路径，而不是项目根路径。

这时候就需要去修改我们打包后的basePath，将打包后的基础路径配置为仓库名，这样静态资源在加载时，会在github的该仓库下进行查找。（其实我一开始是只改了assetsPath，后面发现还是会影响favicon的加载，所以还是直接修改basePath吧）。

但是在本地开发环境时（localhost:3000)时，是不需要加前缀的，因此需多加一个node环境判断。不然路由会默认在app文件夹下找这个basePath名的文件夹，但是又找不到，导致页面返回404（具体可参考官网路由解析）

arduino 复制代码

//next.config.js
const isProd = process.env.NODE_ENV === "production";

/** @type {import('next').NextConfig} */
const nextConfig = {
  output: "export",
  basePath : isProd ? "/repo-name" : "/",  
  images: {
    unoptimized: true,
  },
};

export default nextConfig;

结尾附上next.yml文件（放置在.github/workflows路径下即可）
