Rec*_*con 5 javascript reactjs next.js
我正在尝试在 firebase 函数上运行 Next.js,并且之前已经成功部署过。但是,在添加 webpack 插件 (svgr) 并进行进一步自定义后,我在构建时遇到了错误。它是在 Next.js 自动优化页面时成功编译后发生的。
我的函数文件夹和我的 dev 文件夹的依赖项完全相同,除了函数文件夹有两个附加项(用于 firebase)。
经过检查,它似乎认为我有多个 React 实例。在我的 /app 文件夹之外以开发模式运行应用程序工作正常,但是,在开发模式下在 /functions 文件夹之外运行应用程序仍然无法正常工作。

下一个.config.js
module.exports = {
distDir: "../functions/next",
webpack(config) {
config.module.rules.push({
test: /\.svg$/,
use: ['@svgr/webpack'],
});
return config;

让我们保留 distDir 不变,用 to.next代替../functions/.next。在某种程度上,您可以在构建后立即使用cp .next ../functions/.next. dev当您调用next({ dev: true, ...otherOptions })或设置NODE_ENV=production为 run时,您还需要将值更改为 true firebase serve。
