Question

使用ElasticBeanStalk将我的Node.JS应用程序部署到AWS时遇到了一些麻烦。

一旦部署开始，在运行npm install脚本（由AWS默认）时，我会收到以下奇怪的错误：

material-ui@0.15.4 node_modules/material-ui

任何人都可以帮我调试这个问题吗？我已经花了太多时间试图了解正在发生的事情，但到目前为止没有结果。

谢谢！

Answer 1

显然某些AWS区域确实存在与npm的连接问题（在此issue中相关）并且我通过强制npm通过http而不是https来下载模块来解决它。

为此，我将.npmrc文件添加到项目的根目录中，其中包含以下内容：
registry=http://registry.npmjs.org/

感谢 @Jason Livesay 提示和 @danilojun ，以帮助我找到最佳解决方案！

Answer 2

更新npm为我解决了

npm i -g npm

Answer 3

请粘贴完整的日志。验证VM是否具有足够的网络和其他资源（免费/廉价的AWS内容受到限制）。升级到最新的Node / npm。当您在github isshes中搜索该错误时，请查看有关github npm repo问题的大量评论，例如https://github.com/npm/npm/issues/9418#issuecomment-170244027和其他问题。

我为我正在处理的项目派生的另一个解决方案是检查node_modules文件夹中的源代码，然后禁用自动npm install继承到EB。这可以帮助具有严格依赖性的脆弱节点应用程序。

您需要将以下脚本添加到.ebextensions：

files:
  "/opt/elasticbeanstalk/hooks/appdeploy/pre/50npm.sh":
    mode: "000755"
    owner: root
    group: users
    content: |
      #!/bin/bash

      #set -xe
      #DO NOT RUN NPM...project contains node_modules
      #/opt/elasticbeanstalk/containerfiles/ebnode.py --action npm-install

运行npm install时，回调多次调用
