curlで書き込めないみたいなエラー。

やったこと

sudo suでRootユーザーになってやってみる。→インストールできた。

ってことで権限の問題なのかなと思ったんですが、よくわからなかったので、一度rvmを再インストールしてみると


$ sudo curl -sSL https://get.rvm.io | sudo bash
Downloading https://github.com/rvm/rvm/archive/master.tar.gz

Installing RVM to /usr/local/rvm/
test -f /etc/profile.d/rvm.sh && source /etc/profile.d/rvm.sh
Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,
    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# User,
#
#   Thank you for using RVM!
#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne, Michal & team.

注意書きに

全てのユーザーをrvmグループに追加して再ログインすること
source /etc/profile.d/rvm.sh を実行すること
