[英]Rake tasks in capistrano and cron use wrong ruby version
我需要在部署過程中執行一個 rake 任務。 為此,我在 deploy 命名空間中有一個任務:
desc 'Start Telegram server'
task :start_telegram do
on roles(:app) do
puts "Current path: #{release_path}"
within release_path do
with rails_env: fetch(:rails_env) do
execute :nohup, "bundle exec rake bot:start_poller > #{shared_path}/log/telegram.log 2>&1 & echo $! > #{shared_path}/tmp/pids/telegram-server.pid"
end
end
end
end
它是這樣執行的: after :stop_telegram, :start_telegram
。 日志文件的輸出是:
/var/lib/gems/2.3.0/gems/bundler-2.0.2/lib/bundler/spec_set.rb:87:in `block in materialize': Could not find nokogiri-1.10.3 in any of the sources (Bundler::GemNotFound)

from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
rbenv ruby 版本是 2.5.3, ruby -v
給了我ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-linux]
,我不明白為什么它會查看/usr/lib/gems/2.3.0
。 當 cron 執行 rake 任務時,也會發生同樣的情況。 關於什么可能是錯誤的任何想法? 先謝謝了。
編輯:如果我在服務器上手動執行它: RAILS_ENV=production nohup bundle exec rake bot:start_poller > /home/deployer/apps/aws-rails/www/shared/log/telegram.log 2>&1 & echo $! > /home/deployer/apps/aws-rails/www/shared/tmp/pids/telegram-server.pid
RAILS_ENV=production nohup bundle exec rake bot:start_poller > /home/deployer/apps/aws-rails/www/shared/log/telegram.log 2>&1 & echo $! > /home/deployer/apps/aws-rails/www/shared/tmp/pids/telegram-server.pid
,一切正常。
如果您希望 Capistrano 使用您的 rvm 版本,那么您需要使用 capistrano/rbenv gem
# Capfile
require 'capistrano/rbenv'
# config/deploy.rb
set :rbenv_type, :user # or :system, depends on your rbenv setup
set :rbenv_ruby, '2.4.2'
欲了解更多詳情,請查看以下鏈接
https://github.com/capistrano/rbenv
要在 crons 中使用 rbenv,請將以下內容添加到您的 bashrc
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
我找到了解決方案,應該添加這個$HOME/.rbenv/bin/rbenv exec
,所以,最后,可執行命令應該是這樣的: execute :nohup, "$HOME/.rbenv/bin/rbenv exec bundle exec rake bot:start_poller > #{shared_path}/log/telegram.log 2>&1 & echo $! > #{shared_path}/tmp/pids/telegram-server.pid"
