问题描述
我的应用程序在本地运行，但是当我部署到Heroku时出现问题。这是我的错误，似乎该错误是由添加EJS后无法执行的操作引起的。
My app was working locally but when I deployed to Heroku, there was an issue. This was my error, It seems that the error was caused by something that I failed to do after I added EJS.

阅读此问题后n SO 我需要在 package.json 中添加该依赖项。对于ejs的版本，我运行了 npm list 并得到了它，看来可能还有更多错误要解决。
After reading this question on SO I needed to add that dependency in the package.json . And to the version of ejs I ran npm list and got this, which looks like there might be more errors to address.

推荐答案
我只是通过列出EJS来解决此问题并将其版本添加到我的 package.json 中。
I resolved this just by listing EJS and its version into my package.json .
"ejs": "0.8.5"
如果您不知道所拥有的EJS版本，我发现我的方法是运行 npm list 。
If you do not know the version of EJS that you have, the way I found mine was to run npm list.
这是我当前的整个文件，如果您很好奇它们如何组合在一起以在heroku上进行部署。
Here is my current entire file if you are curious how it all fits in together to deploy on heroku.
{
"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"
}
}
