Capistrano 3到ubuntu 14.04 git錯誤

Question

由於ubuntu服務器上的git錯誤，我的capistrino檢查失敗了。

得到這個日志

我認為這是服務器上git的錯誤。我已經更新了它，但仍然沒有成功。 我ssh到服務器並嘗試直接運行git ls-remote -h命令

DEBUG[d6b0ae0e] Command: ( GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/zarapp/git-ssh.sh /usr/bin/env git ls-remote -h  )
DEBUG[d6b0ae0e]     usage: git ls-remote [--heads] [--tags]  [-u <exec> | --upload-pack <exec>]
DEBUG[d6b0ae0e]     
DEBUG[d6b0ae0e]                          [-q|--quiet] [--exit-code] [--get-url] [<repository> [<refs>...]]

它也說同樣的輸出。 capistrino 3是否運行了錯誤的命令語法或者還有其他問題？

Answer 1

git ls-remote需要一個repo來操作。

這意味着：

• git ls-remote -h總是會失敗

• 但這會奏效：

    git ls-remote -h /local/path/to/a/repo git ls-remote -h origin 

---

正如OP Hemc 評論 ：“ capistrano - git ls-remote -h沒有git url ”確實指出了capistrano版本不匹配（2.x vs. 3.x）

請參閱“ 准備應用程序 ”

deploy.rb是可以指定每個環境通用配置的位置，通常在此處指定存儲庫URL和要部署的用戶。

set :application, 'my app name'
    set :repo_url, 'git@example.com:me/my_repo.git'
    ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }

git ls-remote將使用repo_url執行它。
