找不到模块'mongdb“的Heroku mongoskin [英] cannot find module 'mongdb' heroku mongoskin

问题描述

我的应用程序正在当地寻找，但部署到Heroku的我的模块之一，当无法找到。我用的.gitignore文件忽略node_modules文件夹，并允许Heroku上安装适当的依赖关系。当我运行 Heroku的开放命令，并使用 Heroku的日志 - 尾搜索日志，它显示了这个错误。

My app is working find locally, but when deploying to heroku one of my modules can't be found. I used a .gitignore file to ignore the node_modules folder and allow heroku to install the proper dependencies. When i run the heroku open command and search the logs using heroku logs --tail it shows this error.

我得到的错误是：

本地我的应用程序结构如下：

locally my app structure is as follows:

app/
config/
node_modules/
..
-mongodb
-mongoskin
..
public/

当我使用bash的搜索目录的Heroku我没有看到MongoDB的模块。可能是什么问题？

When I search the heroku directory using the bash I don't see the mongodb module. What could be the issue?

推荐答案

我已经想通了答案。我在本地删除的文件node_modules奔着 NPM安装再次和节点显示这样的警告：

I've figured out the answer. I deleted the node_modules files locally and ran npm install again and node showed this warning:

npm WARN peerDependencies The peer dependency mongodb@~2.0 included from mongoskin will no
npm WARN peerDependencies longer be automatically installed to fulfill the peerDependency 
npm WARN peerDependencies in npm 3+. Your application will need to depend on it explicitly.

我必须明确申报的MongoDB的mongoskin依赖于我的package.json文件照片直接mongoskin是这样的：

I had to declare the mongoskin dependency on mongodb explicitly in my package.json file for mongoskin direclty like this:

"dependencies": {
    ...
    "mongoskin": "2.0.3",
    "mongodb": "^2.0.46",
    ...
   }

我把它推到Heroku和它的工作。

I pushed it to heroku and it worked.
