[英]Capistrano/RVM rake not found
I'm trying to deploy the first rails application using Capistrano. 我正在尝试使用Capistrano部署第一个Rails应用程序。
I'm getting an error while capistrano tries to run rake db:migrate
. 当capistrano尝试运行
rake db:migrate
出现错误。 To be more clear this is the traceback of the exception: 更清楚地说,这是异常的回溯:
[ip] executing command
*** [err :: ip] bash: rake: command not found
command finished in 124ms
failed: "env RAILS_ENV=production bash -c 'cd /home/deployer/website/current && rake RAILS_ENV=production db:migrate'" on ip
And this is the config/deploy.rb
I'm using actually. 这是我实际使用的
config/deploy.rb
。 On the server I've installed RVM (single user installation). 在服务器上,我已经安装了RVM(单用户安装)。

How can I make this run properly? 我该如何使其正常运行?
Of course I already tried to run rake
on the server, and it is found properly. 当然,我已经尝试在服务器上运行
rake
,并且可以正确找到它。
Thanks 谢谢
you break rvm/capistrano
integration by adding this line: 通过添加以下行来破坏
rvm/capistrano
集成:
default_run_options[:shell] = 'bash'
You need to remove it. 您需要删除它。
Also I see a lot of over-engineering in your script, please check my example script which I run from time to time to confirm RVM works as expected: https://github.com/mpapis/ad/blob/master/config/deploy.rb 另外,我在您的脚本中看到很多过度设计的情况,请检查我不时运行的示例脚本,以确认RVM是否按预期工作: https : //github.com/mpapis/ad/blob/master/config/ deploy.rb
