Net :: SSH :: Exception：無法解決compression_client算法

Question

我正在學習/創建我的第一個Capistrano部署。

但是，在我得到任何工作或測試之前，我遇到了問題。

當我運行任何命令時，我得到提到的錯誤。

我可以手動ssh到終端。

下面是完整的調試輸出：

Answer 1

嘗試ssh -vvv your-ip，查看日誌。使用ssh-options中的compression_client是這樣的： set :ssh_options, { forward_agent: true, compression_client: "zlib" }
