在Heroku上找不到模塊'ejs' - Node.js應用程序

Question

我的應用程序在本地工作，但是當我部署到Heroku時，出現了問題。這是我的錯誤，看來這個錯誤是由於我添加EJS後我沒有做的事情造成的。

閱讀this question on SO後我還需要增加在package.json這種依賴性。而對於ejs的版本，我運行了npm list並得到了這個，看起來可能會有更多的錯誤需要解決。

Answer 1

我剛剛上市EJS及其版本到我package.json解決了這個。

"ejs": "0.8.5"  

如果你不知道你有EJS的版本，我發現我的方法是運行npm list。

這是我現在的整個文件，如果你好奇它是如何適合在Heroku上部署的。

{ 
    "name": "application-name", 
    "version": "0.0.1", 
    "private": true, 
    "scripts": { 
    "start": "node app.js" 
    }, 
    "dependencies": { 
    "express": "3.4.4", 
    "jade": "*", 
    "stylus": "*", 
    "ejs": "0.8.5" 
    }, 
    "engines": { 
    "node": "0.10.1", 
    "npm": "1.3.14" 
    } 
}
