Question

我正在尝试在Windows上运行流星应用程序。我在我的机器上运行了本地mongodb，我还在我的系统上设置了环境变量<b>MONGO_URL=mongodb://127.0.0.1:27017/sample</b>。仍然流星应用程序无法连接到它。可能是什么问题。

以下是错误： -

C:\workspace\node-workspace\gm>meteor
[[[[[ C:\workspace\node-workspace\gm ]]]]]

Answer 1

鉴于堆栈跟踪显示meteor仍在尝试连接到端口3002上的mongoDb实例，那么要么您没有正确设置环境变量，要么您没有重新加载cmd shell以获取新值。

您是如何设置 MONGO_URL 的？如果通过系统属性进行设置或更新autoexec.bat，则需要重新加载cmd shell。

您可以通过键入cmd shell来查看当前值：

echo %MONGO_URL%

然后将其设置为您可以执行的当前环境：

set MONGO_URL=mongodb://127.0.0.1:27017/sample

我知道这已经有一段时间了，但我遇到了同样的问题（7月13日）我没有时间弄明白并最终进入Linux安装工作正常。

最近我有时间回到它。以下是google群组中关于此事的一些讨论 - https://groups.google.com/forum/#!topic/meteor-talk/AE6GYrJImAo

我发现Mongo数据库进程甚至没有启动，mongo_runner.js中有些冲突...我的解决方案是手动启动mongo

C:\Program Files (x86)\Meteor\mongodb\bin>mongod -port 3002 --dbpath C:\Users\username\project\.meteor\local\db

上面在所需端口上启动项目，并指定项目的数据库文件夹......之后就像往常一样启动流星。

Answer 3

从版本0.7.1开始，流星mongodb端口为3001，而不是3002.

与Meteor运行的端口相比，端口通常高1（在旧版本的流星版本中为2）。例如，如果Meteor在端口3000上运行，MongoDB将在端口3001

Meteor App无法连接到MongoDB？
