npm install installs，但node_modules爲空

Question

我有一臺運行Ubuntu 16.04的數字海洋虛擬機。我安裝了節點和git。我拉我的回購，並試圖安裝所有的依賴關係。我在項目文件夾中運行npm install。一切都看起來正確安裝。然後我嘗試運行node server.js開始我的應用程序，並且我得到各種各樣的module not found errors。

當我看裏面node_modules，目錄是空的。

任何想法可能發生什麼？

Answer 1

這可能是你的package.json文件不存在或者沒有dependencies或devDependencies。

Answer 2

你必須增加從512mb到1gb的液滴記憶，至少安裝npm模塊。然後你可以回到512MB，如果你想。這爲我修好了。

Answer 3

另一個不需要增加液滴內存的選項（或者，如果您不在具有該功能的服務器上），則是單獨或以小組手動安裝依賴項。在我的情況下，express是我安裝的最大的軟件包，所以我用npm install express手動安裝了該軟件包，然後運行npm install以獲取其餘的。
