rbenv：未安装版本“2.2.3”（由 RBENV_VERSION 环境变量设置）

Question

当我运行部署脚本时，出现错误：

[cb123fad]  rbenv: version `2.2.3' is not installed (set by RBENV_VERSION environment variable)
DEBUG [cb123fad]
(Backtrace restricted to imported tasks)

Capfile 有 set :rbenv_ruby, '2.2.3'

服务器和本地我都安装了ruby 2.2.3p173

将 set :rbenv_ruby 的值从 2.2.3 更改为 2.2.3p173 无效。

Answer 1

我解决了同样的问题设置:rbenv_path。你的应该是：
set :rbenv_path, '/home/your/.rbenv/'

这必须在 deploy.rb 内。

Answer 2

以上回答对我不起作用。 gem update --system，那么 bundle install 会导致 fatal: No live threads left. Deadlock? 错误。

bundle exec cap development deploy

完成部署如果gem 'sshkit', '~> 1.7.1'加速。

但是，可能发生的情况是 sshkitgem 可能会更新到 1.8.0 或更高。在这种情况下，假设标准 Ubuntu 服务器设置，在 deploy.rb

set :rbenv_path, '$HOME/.rbenv'

将允许部署完成。

Answer 3

https://github.com/capistrano/sshkit/issues/303 and https://github.com/capistrano/rbenv/pull/59

注意事项

set :rbenv_path, '/home/your/.rbenv/' # works
set :rbenv_path, '~your/.rbenv/' # doesn't work

此问题是由于 sshkit 的更改造成的。
