Question

我用Officejs和office-ui-fabric-react用打字稿写了一个字。本地运行的服务器一切正常。我想通过Cloudfront部署到AWS S3中。我正在使用npm run build和npm run deploy进行构建（使用部署命令“ aws --profile profile-name s3 sync dist / s3：// bucketname”。在S3存储桶中启用了静态网站托管。所有文件都来自在bucket中可以看到dist目录。在将add in插入到带有manifest.xml文件并指向Cloudfront端点的Word中后，出现错误“ Uncaught ReferenceError：未定义React”。直接指向S3静态Web端点。要查看是否错过了我使用上述步骤部署的通用create-react-app，并且运行良好，我假设问题出在我的webpack配置上，所以我ve包括在这里（常见和产品）。我很乐意包含其他需要的东西。如果使用AWS引起问题，我也愿意接受其他部署选项。

webpack.common.js：

原来，它正在寻找全局定义的“ React”，因此没有通过npm模块进行解析。在webpack.prod.js文件中，删除以下内容可以解决问题：

externals: {
    'react': 'React',
    'react-dom': 'ReactDOM'
},
