我下载了示例网络聊天文件并使用$ snapcraft snap. 如何运行快照？
网络聊天文件 https://github.com/ubuntu-core/snapcraft/tree/master/examples/webchat
$ snap list
Name Version Developer
ubuntu-core 16.04+20160419.20-55 canonical
webchat 0.0.1
$ webchat.run
command not found
$ snap webchat
error: Unknown command 'webchat'
当我直接调用它时，网络聊天确实有效，如下所示
$ node /home/chris/software/snapcraft_test/parts/webchat/install/lib/node_modules/webchat-for-a-snap/webchat.js
