Javascript 部署到Cloud Foundry的应用无法启动

我尝试将Node.js应用程序部署到Bluemix，但失败了

运行cf logs IssueTracker-recent时，我看到以下错误：

我是云铸造的新手，所以不知道下一步该做什么。如何解决此问题？

您的应用程序中似乎缺少依赖项：错误：找不到模块“webpack”

CF运行的启动应用程序的命令是NODE_ENV=production NODE./dist/server.generated.js。尝试在本地运行，看看是否可以复制

您可能还希望尝试在干净的VM上运行，以排除在开发人员工作站上全局安装缺少的依赖项的情况。当您的应用程序在CF上运行时，全局安装的依赖项将不可用。唯一可用的是NPM/Thread根据您的package.json文件安装的内容

---

希望有帮助

在我的例子中，package.json有错误的条目。

---

请交叉验证它是否在我的本地计算机上工作。我将尝试使用干净的VM以排除全局依赖的可能性。当我最初尝试部署我的应用程序时失败，错误为失败：应用程序上载无效：无效的zip存档。经过一些研究，我发现这是因为存在节点_模块。我删除了文件夹并进行了另一次推送。这一次，它似乎已部署，但由于缺少依赖项而无法启动。如何安装它们？请检查package.json并确保运行应用程序所需的所有内容都在该文件中。node.js buildpack将运行npm并安装该文件中的所有依赖项。当我将以下内容放入依赖项中时，它起到了作用：webpack@4.6.0网页包开发-middleware@3.1.3网页包热-middleware@2.22.1我已经在devdependences中列出了这些。我不相信安装了dev依赖项，因为它们通常只会被使用促进发展。buildpack启用生产->哪个条目错误？为什么您认为您的案例与问题中的案例相同？它指向server.js而不是index.js进行启动，这导致启动失败。同样，webpack模块不是上下文，因此请验证package.json中的依赖项。
