轨道3.1和资产管道：使用Capistrano进行部署时出现问题 [英] Rails 3.1 and Asset Pipeline: Trouble on deploying with Capistrano
本文介绍了轨道3.1和资产管道：使用Capistrano进行部署时出现问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
load'deploy /资源在我的 Capfile 中，如下所示： ＃如果您使用Rails的资产管道，则取消注释
加载'deploy / assets'
现在，当我运行 cap deploy 命令时，我收到以下错误（错误在底部说明）：

与Capistrano相关的代码是错的？如何正确使用加载'deploy / assets'语句，以使部署过程正常工作？
解决方案
您是否尝试过简单地定义自己的任务？这就是我所做的一切当我遇到这个问题：
task：precompile，：role => ：app do
运行cd＃{release_path} /& rake assets：precompile
end
afterdeploy：finalize_update，deploy：precompile
你需要 RVM初始化，如果您使用RVM
I just switched from Ruby on Rails 3.0.10 to 3.1.0 and I would like to deploy my asset files by using the Capistrano gem (my local machine is a MacOs running Snow Leopard, my remote machine is running Ubuntu 10.04 Lucid). So, as wrote in the Official Guide, I uncomment the load 'deploy/assets' in my Capfile like this:
# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'
Now, when I run the cap deploy command I get the following error (the error is explained at the bottom):
...

Where the code related to Capistrano is wrong? How to use correctly the load 'deploy/assets' statement in order to make the deployment process to work?
解决方案
Have you tried simply defining your own task? That's what I did when I ran into this issue:
task :precompile, :role => :app do
run "cd #{release_path}/ && rake assets:precompile"
end
after "deploy:finalize_update", "deploy:precompile"
You do need RVM initialization for this if you use RVM
这篇关于轨道3.1和资产管道：使用Capistrano进行部署时出现问题的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
