Capistrano部署失敗 - SSH工具包？

Question

前言說我是Capistrano的新手。話雖如此，我已經有了一個功能性的應用程序，我曾使用過Capistrano多次部署過。我做了幾個更新的應用程序，並嘗試cap production deploy。我得到這個錯誤輸出：

** Invoke deploy:check (first_time) 
** Execute deploy:check 
** Invoke git:check (first_time) 
** Invoke git:wrapper (first_time) 
** Execute git:wrapper 
00:00 git:wrapper 
     01 mkdir -p /tmp/dentalimager/ 
cap aborted!

它在我看來像Capistrano和SSHkit之間有問題。我回頭看看我的Gemfile，根據我的git repo，在bundle update之後顯示SSHkit從v 1.10.0變爲v 1.11.1。

sshkit gem中的更新是否會導致此問題，或者我應該在別處查看？如果是這樣，我將如何恢復到1.10.0並在我的Gemfile中指定特定版本以避免將來出現問題？

Answer 1

是的，這可能是由SSHKit 1.11.1引入的錯誤。

首先，我建議在GitHub上打開一個問題，將此問題報告給SSHKit團隊。這是解決這個問題的最快方法。

在此期間，使用SSHKit的舊版本，並避免這個問題，你可以用你的Gemfile爲「針」的舊版本。添加到您的Gemfile：

# Place this next to gem "capistrano", i.e. in the :development group 
gem "sshkit", "1.10.0" 

然後運行

bundle update sshkit
