EC2：无法安装ruby

Question

I am following this tutorial and am stuck at trying to install ruby using rvm (scroll down to see the command in the link)

I have searched online for a variety of solutions but nothing seems to work. How can I resolve the issues below?

rvm install ruby

Searching for binary rubies, this might take some time.

Found remote file https://rubies.travis-ci.org/ubuntu/14.04/x86_64/ruby-2.3.0.tar.bz2 Checking requirements for ubuntu.

Installing requirements for ubuntu. mkdir: cannot create directory '/usr/local/rvm/log/1463248047_ruby-2.3.0': Permission denied

tee: /usr/local/rvm/log/1463248047_ruby-2.3.0/update_system.log: No such file or directory

Updating system......... Error running 'requirements_debian_update_system ruby-2.3.0',

tail: cannot open '/usr/local/rvm/log/1463248047_ruby-2.3.0/update_system.log' for reading: No such file or directory Requirements installation failed with status: 1.

Notes for debugging:

1) The previous steps to install rvm have been taken already. Mainly:

su - deploy
gpg --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3
\curl -sSL https://get.rvm.io | bash -s stable

2) I tried running sudo rvm install ruby , but got the following error

sudo: rvm: command not found

尝试通过此命令更改rvm目录的权限：

sudo chmod -R a+xwr /usr/local/rvm
