Question

我有一个visual studio团队服务构建定义，第一步是“npm install”。此定义部署到azure Web应用程序。

NPM完成没有错误，但是在访问Web应用程序时，会抛出错误“找不到模块'express'”。当从“wwwroot”文件夹手动运行“npm install”时，web应用程序文件和package.json位于该文件夹中，命令再次成功完成，但错误仍然存在。

然而，当我从“wwwroot”文件夹中删除“node_modules”并再次运行“npm install”时，错误消失了，Web应用程序按预期运行！

如何修复构建定义，以便每次部署都不需要这些手动步骤？

我的package.json的相关摘录如下：

 "dependencies": {
    "express": "^4.13.4",
    "pug": "^2.0.0-alpha7",
    "bluebird": "^3.4.1",
},

npm日志位于以下位置：

Answer 1

我试图利用 npm install ＆gt; 存档文件＆gt; 复制和发布构建工件＆gt; Azure Web应用程序部署工作流程以安装程序包，打包应用程序并部署到Azure Web App。

以下是详细的构建步骤参数：

您可以参考https://www.visualstudio.com/docs/release/examples/nodejs/node-to-azure-webapps#build了解有关在类似情况下在VSTS中构建和部署工作流程的更多信息。

除非首先删除node_modules文件夹，否则NPM安装不起作用？
