heroku - 不能運行rake db：migrate - 沒有這樣的文件 - 時間

Question

我是Postgres和Heroku的新手。我試圖將我的應用程序推送到Heroku，並嘗試在heroku中運行rake db：migrate命令。

heroku run rake db:migrate 

當我運行它

rake aborted!

Tasks: TOP => db:migrate => environment 

我試圖消除從我的位置控制器需要「時間」行，但此並沒有改變什麼，我得到這個錯誤。

謝謝！

我想你的意思是require 'time'而不是Time。這是ruby標準庫文件的名稱（即使模塊本身是Time）。
