Meteor App無法連接到MongoDB？

我想在Windows上運行流星應用程序。我在本機上運行了本地mongodb，並且在我的系統上還設置了環境變量<b>MONGO_URL=mongodb://127.0.0.1:27017/sample</b>。流星應用程序仍然無法連接到它。可能是什麼問題。Meteor App無法連接到MongoDB？

下面是錯誤： -

鑑於堆棧跟蹤說，流星仍試圖連接到MongoDB實例上的端口3002，那麼無論你have't正確設置環境變量或您尚未重新加載cmd shell以獲取新值。

你是怎麼設定的MONGO_URL？如果通過系統屬性設置它或更新autoexec.bat，則需要重新加載cmd shell。

你可以看到當前的值是通過在cmd shell中鍵入什麼：

echo %MONGO_URL%

然後將其設置爲當前ENV你可以這樣做：

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

我知道它已經一段時間但是我遇到了同樣的問題（在7月13日），我沒有時間弄清楚，最終轉到了一個可以正常工作的Linux安裝。

但是最近我有一些時間回到它。下面是在谷歌這個問題的一些討論集團 - https://groups.google.com/forum/#!topic/meteor-talk/AE6GYrJImAo

我發現蒙戈DB過程中甚至沒有開始，mongo_runner.js內的一些矛盾......我的解決辦法是開始蒙戈手動

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

上面的項目在需要的端口上啓動，併爲您的項目指定數據庫文件夾......在這之後，您將像往常一樣啓動meteor。

作爲版的0.7.1流星mongodb的端口是3001，而不是3002

端口通常爲1以上（2在舊版本的流星的情況下）大於流星其上運行的端口是。例如，如果Meteor在端口3000上運行，MongoDB將在端口3001上
