我有一个新的Angular SSR项目，规格如下：

ts.config:

{
  "compileOnSave": false,
  "compilerOptions": {
    "strict": true,
    "noImplicitOverride": true,
    "noPropertyAccessFromIndexSignature": true,

    "strictTemplates": true
  },
  "files": [],
  "references": [{ "path": "./tsconfig.app.json" }, { "path": "./tsconfig.spec.json" }]
}

以及package.json中的这些库

  }
}

我本地的Node版本是 v24.14.1

在我的cPanel中，我把项目创建为Node.js项目，并将Node.Js版本设为24.13.0，并将应用启动文件指向我的 server.mjs

无法构建。我得到：503服务不可用

服务器会创建一个 stderr.log 文件，内容如下：

在我调查问题时，似乎是Node版本的问题，因为在版本15之前，'??=' 不是一个有效表达式。

但我看不出Node版本应该低于我现在使用的24的地方，无论是在本地编译还是在服务器上。

我在cPanel终端中的我的项目里执行node -v，当然得到的是24.13.0。

有没有人遇到过类似的问题，或者不降级Node.js版本就能解决吗？

解决方案

我解决了。

首先（为了保持初始设置）我把 tsconfig 设置为：

{
  "compileOnSave": false,
  "compilerOptions": {
    "strict": true,
    "noImplicitOverride": true,
    "noPropertyAccessFromIndexSignature": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "skipLibCheck": true,
    "isolatedModules": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "ES2022",
    "useDefineForClassFields": false,
    "module": "preserve",
    "resolveJsonModule": true
  },
  "angularCompilerOptions": {
    "enableI18nLegacyMessageIdFormat": false,
    "strictInjectionParameters": true,
    "strictInputAccessModifiers": true,
    "strictTemplates": true
  },
  "files": [],
  "references": [
    {
      "path": "./tsconfig.app.json"
    },
    {
      "path": "./tsconfig.spec.json"
    }
  ]
}

这篇帖子中原本放的那个，在我第一次部署前做了一些“改进”后的修改。

有了它我重新尝试，错误消失了，但我仍然遇到503错误，而且没有日志。只有一个空日志文件。

所以，在Gemini的帮助以及大量内部日志的辅助下，我意识到问题在于NodeJs项目试图在主项目文件夹中找到构建产物中的chunk文件，而不是在dist文件夹中。

我在项目文件夹中创建了一个 index.js（在你有 .htaccess 和 dist 文件夹的地方）：

import path from 'node:path';
import { pathToFileURL } from 'node:url';
import http from 'node:http';

const serverFolder = path.join(process.cwd(), 'dist/my-project/server');
const serverFile = path.join(serverFolder, 'server.mjs');

console.warn("--- PROCESO DE ARRANQUE ---");

try {
    process.chdir(serverFolder);

    import(pathToFileURL(serverFile).href)
        .then((ngModule) => {
            console.warn("--- SERVIDOR ANGULAR SSR CARGADO ---");

            // Si cPanel no nos da un puerto num��rico, usamos el socket de Passenger
            const port = process.env.PORT || 'passenger'; 

            // Verificamos que Angular nos entreg�� su manejador de peticiones moderno
            if (typeof ngModule.reqHandler === 'function') {
                console.warn("Iniciando HTTP Server nativo con reqHandler de Angular...");

                // Creamos el servidor y le pasamos el control a Angular
                const server = http.createServer(ngModule.reqHandler);

                server.listen(port, () => {
                    console.warn(`[�0�7XITO TOTAL] Servidor escuchando peticiones en: ${port}`);
                });

            } else {
                console.warn("ERROR: reqHandler no es una funci��n. Exportaciones:", Object.keys(ngModule));
            }
        })
        .catch(err => {
            console.error("--- ERROR DENTRO DE SERVER.MJS ---");
            console.error(err);
        });

} catch (err) {
    console.error("--- ERROR AL CAMBIAR DIRECTORIO ---");
    console.error(err);
}

console.logs 是西班牙语的，不过你可以翻译它们 :D

最后一步：我把 index.js 设置为应用启动文件，而不是之前的 dist/my-project/server/server.mjs。

就这样。现在一切都正常工作了。

P.S.当然别忘了在 angular.json 的 allowedHosts 属性中填写你的域名。
