Hiredis fails when deploying with capistrano

Question

When trying to deploy an app with ruby 2.2.0 and rails 4.2.0 with gems redis v3.0.1 and hiredis v0.4.5 task which responsible for interactions with redis server fails with the following error:

.....ruby/2.2.0/gems/hiredis-0.4.5/lib/hiredis/ext/hiredis_ext.so: undefined symbol: rb_thread_select
cap aborted!

Does anyone faced the same issue?

Answer 1

rb_thread_select已被弃用并从中继中删除，因此您将需要使用hiredis的当前版本，该版本已删除了rb_thread_select依赖项。
