NPM install not working unless node_modules folder is first deleted?
我有一个Visual Studio团队服务构建定义,第一步是" npm install"。此定义将部署到azure Web应用程序。
NPM顺利完成,但是在访问Web应用程序时,引发错误"找不到模块'express'"。从Web应用程序文件和package.json所在的" wwwroot"文件夹中手动运行" npm install"时,该命令再次成功完成,但错误仍然存??在。
但是,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应用程序将按预期运行!
如何修复我的构建定义,以便在每个部署中都不需要这些手动步骤?
我的package.json中的相关摘录如下:
1 2 3 4 5 | "dependencies": { "express":"^4.13.4", "pug":"^2.0.0-alpha7", "bluebird":"^3.4.1", }, |
