Question

在我的Ubuntu 16.04 VM上，我根据https://hyperledger.github.io/composer/installing/using-playground-locally.html安装了Hyperledger Composer Playground。

单击“部署新业务网络”，然后通过http://localhost:8080/api/getSampleList调用从npm加载启动器模板。我得到的回应是：

{ “错误”： “代码”： “ECONNREFUSED”， “错误号”： “ECONNREFUSED”， “系统调用”： “连接”， “地址”： “151.101.36.162”， “端口”：443}}

乍一看，这看起来像代理相关的问题，但我很确定我的系统已正确配置以供代理使用（因此环境变量全部设置，Firefox和Chrome都配置为使用我们公司的代理）。

如果我尝试通过cURL调用相同的http GET请求（我使用了“copy as cURL”-feature），我会得到相同的响应。

进一步挖掘我发现http://localhost:8080/assets/npmlist.json列出了缺少的依赖项：

以下是来自hyperledger / composer-playground docker容器的日志记录输出的片段，通过docker log“container-id”（可能相关？）

非常感谢任何提示如何进行。

看来你是代理人的背后？ VPN连接还是其他？

若是，请看一下 https://forum.freecodecamp.org/t/npm-behind-a-proxy-server/19386 用于允许npm通过代理的命令

解决了代理/连接问题后。建议对Docker进行清理，并按照下面的doclink中的说明重新运行curl命令，然后再次尝试安装。 Doclink - ＆gt; https://hyperledger.github.io/composer/installing/using-playground-locally.html
