权限被拒绝@ dir_s_mkdir（Errno :: EACCES）-在应用程序运行时

Question

I have a ruby web app configured, with all the gems installed etc. It runs fine through my apache server, but now I have to debug something (which I'm still figuring out) and I need to run the rails server -b (ip) -p (port) command. However I get the following outcome:

=> Booting Thin
=> Rails 4.0.12 application starting in development on http://192.168.39.163:3004
=> Run 'rails server -h' for more startup options
=> Ctrl-C to shutdown server
Exiting

I've changed ~/.rbenv's owner to myself, I've tried setting the permissions to 775 on that folder. It keeps giving me this error. Any more ideas?

Answer 1

Create a folder in /home/vicky/vanerum/ with name tmp .

_{For a case, create a folder pids in /home/vicky/vanerum/tmp .
I assume the problem in thin server, it not able to create folder.}
