我正在使用Postgres數據庫在Travis CI中測試示例Django應用程序。我爲在我的開發環境中成功通過的模型編寫了一些基本測試。當我的代碼推到特拉維斯出現以下錯誤：Django應用程序在Travis CI中失敗：服務器未在本地主機上運行
特拉維斯鏈接：https://travis-ci.org/Navajyoth/django-travis/jobs/64052563
github上鍊接：https://github.com/Navajyoth/django-travis

在我的機器psycopg2不顯示任何錯誤或警告，並順利通過了tests.Only特拉維斯CI顯示了這個錯誤。 –
這是因爲你的本地機器上安裝了postgresql服務器，而每當你啓動一個沒有安裝postgres服務器的版本時，travis會創建一個不同的虛擬機。 –
@NavajyothMS：您是否閱讀過關於使用postgresql的travis文檔？你的問題的答案就在其中。在第一頁的頂部，標題爲「在您的構建中使用PostgreSQL」... – spectras
