在bluemix node.js应用程序上运行node.js

我对Bluemix和node.js非常陌生。我有一个node.js应用程序，我想在Bluemix中运行，但我不知道如何在它上实际运行node.js。当我尝试在bluemix上打开站点时，我的javascript文件出现了一个错误，即没有定义require函数，这意味着node.js没有运行。我是否应该更改package.json文件中的某些内容以允许特定的javascript文件运行node.js或其他什么？对不起，我太笨了

忘了我说过的node.js函数吧。我在这个应用程序中使用视觉识别，以前运行时没有出错的文件没有包含我的所有文件。在将项目的其余部分推送到bluemix后，我在上面的日志文件中遇到了错误。我推送的文件是视觉识别所需的node_模块api以及从app.js发出的api调用。

您能发布日志文件吗？这就是您的意思吗？请提供命令cf logs--recentPlease的输出使用cf--recentIt输出整个日志似乎缺少必需的库。package.json是否包含必需的依赖项？通过npm安装时在您的计算机上，您可以使用“npm install--save”。它更新package.json以允许buildpack检索所有必需的lib。
