Capistrano 使用 rvm 和 git 部署 [git 发布失败]

Question

您好，我在部署我的应用时遇到问题。 我无法部署我的应用程序，因为我的 git release 有问题

有人知道为什么会这样吗？ 可能是 rvm 的问题什么的，我花了很多时间但没有成功

Answer 1

• 我也遇到了和你一样的问题（但我的情况是部署到特定的分支），有人建议在这里Capistrano error tar: This does not look like a tar archive。但是他给出了 2 个不适合我情况的选项，我不想删除我当前的 repo。
• 所以经过 1 小时的变通后，我有一个解决方案：

• 例如：

  • 之前：(deploy/production.rb)

    set :branch, ENV["BRANCH_NAME"] || "master"
    (I stay at master branch then run command)
    BRANCH_NAME=another_branch_name cap production deploy
    

    然后我得到一个类似上面的错误

  • 之后：(deploy/production.rb)

    set :branch, `git rev-parse --abbrev-ref HEAD`.chomp
    (I stay at another_branch_name then run command)
    cap production deploy
    

    错误已修复。
