Question

我想我已经在我的机器上正确设置了Capistrano3，它应该连接到我的服务器。当我运行cap production deploy（在我的机器上）时，我收到以下错误信息：

DEBUG [2959f403] Running /usr/bin/env [ -d ~/.rbenv/versions/2.1.2 ] as [user@myIP]
DEBUG [2959f403] Command: [ -d ~/.rbenv/versions/2.1.2 ]
DEBUG [2959f403] Finished in 0.420 seconds with exit status 1 (failed).
ERROR rbenv: 2.1.2 is not installed or not found in ~/.rbenv/versions/2.1.2
(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as [user@myIP]: exit

SystemExit: exit

Tasks: TOP => rbenv:validate
(See full trace by running task with --trace)

在我的机器上（iMac）：

$ ruby -v
ruby 2.1.2p95
$ rbenv -v
rbenv 0.4.0
$ which rebind
/usr/local/bin/rbenv

在我的服务器上（ubuntu）

$ ruby -v
ruby 2.1.2p95
$ rbenv -v
rbenv 0.4.0-151-g83ac0fb
$ which rebind
/home/[user]/.rbenv/bin/rbenv

任何想法如何解决这个问题？

Answer 1

如果/home/[user]/.rbenv/versions是服务器上的空目录，那么您没有安装任何版本的ruby。

尝试在服务器上运行rbenv install 2.1.2。您可能需要先安装ruby-build插件。
