Rails /tmp permission denied

Question

I am trying to run integration test on my *nix development machine, but test can't execute, because permission denied.

ActionView:Template:Error: Permission denied @  dir_s_mkdir - home/alan/app/tmp/cache/asssets/test

Rails version is 4.2.0, Ruby 2.2.2p95. I'm using built in Rails server (Webrick). Processses are running under user alan, and tmp/ is owned by me (alan).

rake tmp:cache:clear and restarting server didn't do the trick.

ls -alh outpuh is as follows:

Answer 1

因为它是您的开发环境，所以将tmp和log文件夹的权限设置为755或777总是一个好主意。

chmod -R 755 tmp

Answer 2

Probably you somehow denied +x on your directory. Just set it to all folder hierarchy (for your own user):

chmod +x /home
chmod +x /home/alan
chmod +x /home/alan/app
rm -rf /home/alan/app/tmp
mkdir /home/alan/app/tmp
chmod +x /home/alan/app/tmp
