cap部署：冷失败'没有这样的文件或目录 - git rev-parse master'错误 [英] cap deploy:cold fails with 'No such file or directory - git rev-parse master' error

问题描述

服务器运行Ubuntu 10.4服务器（64位）

本地机器是运行Windows XP。

存储库位于github上

我已成功运行

  cap deploy：setup 
  

但是当我运行时

  cap deploy：cold 
  

我得到以下错误：

解决方案

好吧，我已经取得了一些进展。

看起来错误表明在本地系统（win xp）上找不到git ls-remote命令。作为测试，我打开了GIT Bash shell并尝试了命令 - 它工作正常。接下来，我尝试了

  cap deploy 
  

来自GIT Bash shell。找不到命令。好的，我添加了我的导轨路径

D：\Rails\ruby\bin
blockquote>

添加到windows'path'变量中。现在，尝试

  cap deploy 
  

$ b $来自bash shell的b

。这似乎解决了这个问题，现在导致我的下一个问题

  ** [xxxxxxxx.com :: out]克隆到/ var / www / fx / shared / cached-copy ... 
 ** [xxxxxxxx.com :: err] Permission denied（publickey）。 
 ** [xxxxxxxx.com :: err]致命：远端意外挂断
  

我可以使用相同的公钥成功运行我的linux系统中的cap deploy。另外，我可以用这个键从这款笔记本电脑上推送到我的Github回购。当然，问题的关键应该在服务器上，但是如果它运行时，我从linux机器运行'cap'，为什么它不能从这里运行？

I am trying to deploy my rails application for the first time.

Server is running Ubuntu 10.4 server (64bit)
Local machine is running Windows XP.
Repository is at github

I have successfully run

cap deploy:setup

but when I run

cap deploy:cold

I get the following error:

    end
end

  after 'deploy:setup', 'deploy:create_dbyaml'
  after 'deploy:update_code', 'deploy:symlink_dbyaml'

  after "deploy", "deploy:cleanup"

and now I'm stuck...

Any help would be greatly appreciated.

Thanks,
Jon

解决方案

Ok, I have made some progress.

It seems that the error indicates that the git ls-remote command could not be found on the local system (win xp). As a test, I opened the GIT Bash shell and tried the command - it worked. Next, I tried

cap deploy 

from the GIT Bash shell. Command not found. OK, I added my rails path

D:\Rails\ruby\bin

to the windows 'path' variable. Now, try

cap deploy

from the bash shell. This seems to have solved this problem, which now leads to my next problem

** [xxxxxxxx.com :: out] Cloning into /var/www/fx/shared/cached-copy...
** [xxxxxxxx.com :: err] Permission denied (publickey).
** [xxxxxxxx.com :: err] fatal: The remote end hung up unexpectedly

I can successfully run cap deploy from my linux box with the same public key. Also, I can push to my Github repo from this laptop with this key. Of course, the key in question should be on the server, but if it works when I run 'cap' from the linux box, why wouldn't it run from here?
