Heroku聯繫人應用程序：node server.js無法運行

Question

我從Heroku startup guide獲得了該項目併成功進行了部署。但是，當我嘗試在本地運行它時，我正面臨着這個錯誤：

18 error Or if that isn't available, you can get their info via:

18 error  npm owner ls MEAN 
18 error There is likely additional logging output above. 
19 verbose exit [ 1, true ] 

我想在此獲得一些幫助。我和其他一些人在這一點上遇到了麻煩。

確保您在本地運行了npm install，並且您有一個名爲MONGODB_URI的環境變量，該環境變量具有運行mongodb實例的有效URL。另外，如果您從命令行調用node server.js，則可能會發現更詳細的日誌記錄以幫助您縮小問題範圍;一個npm發出的通常是非常不透明的。
