运行 Meteor 包的 Raspberry Pi 引发调用堆栈异常答案

【问题标题】：Raspberry Pi running Meteor bundle throws call stack exception运行 Meteor 包的 Raspberry Pi 引发调用堆栈异常
【发布时间】：2016-06-22 08:44:23
【问题描述】：

我已在 Raspberry Pi 上安装了 Node.js，并尝试在其上运行 Meteor.js 排行榜示例。我已将其捆绑并复制到 Pi。我已经设置了我的 MONGO_URL 和 npm 安装的 Fiber（经过一些麻烦）。当我尝试运行时：

$ node main.js

我得到一个Maximum call stack size exceeded 异常。

  /home/pi/bundle/server/server.js:143
  }).run();
  ^
  RangeError: Maximum call stack size exceeded

我用--trace 运行命令并得到了这个：

我可以跟踪此问题的最后一个位置是在文件中：

app/packages/mongo-livedata/mongo_driver.js

大约在第 10 行：

var MongoDB = __meteor_bootstrap__.require('mongodb');

我安装了最新的 npm (1.1.50) 并在全球范围内安装了 mongodb。我指的是 mongolab.com 上托管的 mongodb。我创建了一个简单的测试来连接和插入一些记录。它使用与我尝试用于 Meteor 的完全相同的 url，并且按预期工作：

var connect = require('mongodb').connect;
var url = 'mongodb://<user>:<password>@<cloud_id>.mongolab.com:<port>/<database>';
connect(url, function(err, db) {
    db.collection('test', function(err, collection) {
       // Insert 3 records
        for(var i = 0; i < 3; i++) {
          collection.insert({'a':i});
        }
    });
});

我不太了解跟踪消息，但似乎 FormatString 调用是触发异常的原因。有什么建议吗？

更新：

我对此进行了更多调试，并将问题与加载此处显示为filename 的特定 mongodb 模块隔离开来。单步执行一段时间后，模块似乎在递归地包含自身。

break in module.js:311
Watchers:
  0: path = ...
  1: parent = ...
  2: filename = "/home/pi/bundle/server/node_modules/mongodb/lib/mongodb/connection/repl_set.js"
 
 308   var hadException = true;
 309 
 310   try {
 311     module.load(filename);
 312     hadException = false;
 313   } finally {
 314     if (hadException) {
 315       delete Module._cache[filename];
 316     }
 317   }

【问题讨论】：

@Wilfred，你是对的，我目前指向托管的 mongodb。我更新了我的问题以澄清这一点。

标签： node.js mongodb meteor raspberry-pi mlab

【解决方案1】：

很遗憾，我认为 MongoDB 目前不支持 ARM 架构，请参阅https://jira.mongodb.org/browse/SERVER-1811

但是，您可以在另一台机器上运行 Mongo 并将驱动程序连接到该机器，或者如果您真的希望它在您的树莓派上运行，您可以尝试 unofficial build

【解决方案2】：

确实，正如 Wilfred Knievel 所指出的，MongoDB 目前不支持 ARM 架构。我已经提供了 MongoDB 的（非官方）二进制文件，因此您无需重新编译它们（因为这是一个相当长/棘手的过程）。这些二进制文件，连同一个示例程序（C 语言）are available here

【解决方案3】：

不确定你现在是否在我们的流星万能叉

https://github.com/4commerce-technologies-AG/meteor

但我们在那里讨论了许多问题。还有一些关于fibers和mongo的错误。请查看（已关闭）问题并查看 bintray 上的预构建二进制文件，网址为

https://bintray.com/4commerce-technologies-ag/meteor-universal/arm-dev-bundles/1.3.3.1/view#files/arm_dev_bundles

您也可以使用 node 和 mongo tgz 来启动服务。

希望有所帮助汤姆
