【问题描述】：

当我在共享主机服务器上运行“npm run build”时，它会抛出一个错误：spawn ENOMEM 它在我的本地主机上运行良好，并且在托管服务器上运行了几周，直到昨天。

我正在使用 express 和 next js 。 这是我的 server.js

const express = require( 'express' );
const next    = require( 'next' );

// Import middleware.
const routes = require( './routes' );

// Setup app.
const app     = next(  dev: 'production' !== process.env.NODE_ENV  );
const handle  = app.getRequestHandler();
const handler = routes.getRequestHandler( app );

app.prepare()
  .then( () => 

    // Create server.
    const server = express();

    // Use our handler for requests.
    server.use( handler );

    // Don't remove. Important for the server to work. Default route.
    server.get( '*', ( req, res ) => 
      return handle( req, res );
     );

    // Get current port.
    const port = process.env.PORT || 8080;

    // Error check.
    server.listen( port, err => 
      if ( err ) 
        throw err;
      

      // Where we starting, yo!
      console.log( `> Ready on port $port...` );
     );
   );

我查看了交换空间/内存，似乎没问题

             total       used       free     shared    buffers     cached
Mem:         31906      31330        575         21       2982      16900

Swap:         8191          0       8191

我也试过NODE_OPTIONS=--max-old-space-size=2048 npm run build 还是不行

有人知道怎么回事吗？

【问题讨论】：

如果我没记错的话，你只有 32 Mb 的可用内存......

我遇到了同样的问题，但在仅使用 Webpack 和 Jest 而不是 Next.js 的仅前端 React 应用程序上。

【参考方案1】：

它似乎与 NextJs 版本 9 相关，因为它在构建应用程序时消耗了太多内存。您可以在此处找到有关该问题的讨论：https://github.com/zeit/next.js/issues/7929

版本 8 似乎没有这个问题，所以如果您可以选择降级，您现在可以这样做。

此外，如果这仍然没有帮助，在 next.config.js 中禁用最小化将减少内存使用：

module.exports = 
    webpack: (config, options) => 
        config.optimization.minimize = false;
      return config
    
  

如果您不想排除最小化，我发现使用版本 8，您可以在本地构建应用程序并将已构建的文件夹移动到共享主机，而无需再次在共享主机上运行“下一个构建”。我无法在版本 9 中做到这一点。

更新：在 NextJs 8.1 版上测试
