rbenv：未安裝版本“ 2.2.3”（由RBENV_VERSION環境變量設置）

Question

運行部署腳本時，出現錯誤：

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

Capfile已將set :rbenv_ruby, '2.2.3'

服務器和本地我已經安裝了ruby 2.2.3p173

從值更改2.2.3到2.2.3p173為set :rbenv_ruby沒有工作。

Answer 1

我解決了相同的問題設置:rbenv_path 。 您應該是：
set :rbenv_path, '/home/your/.rbenv/'

這必須在deploy.rb內部。

Answer 2

上面的答案對我不起作用。 gem update --system ，然后bundle install將導致fatal: No live threads left. Deadlock? fatal: No live threads left. Deadlock? 錯誤。

bundle exec cap development deploy

如果已設置 gem 'sshkit', '~> 1.7.1'則完成部署。

但是，可能會發生sshkit gem可能更新為1.8.0或更高版本的情況。 在這種情況下，假設在deploy.rb中設置了標准的Ubuntu服務器

set :rbenv_path, '$HOME/.rbenv'

將允許部署完成。

Answer 3

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

筆記

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

由於sshkit的更改而創建了此問題。
