rvm install 1.9.2权限被拒绝

Question

Installing RVM on Ubuntu 11.04.

Followed the instructions here: http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you

When it comes time to install Ruby, I get a permission denied exception.

kevinwmerritt@ubuntu:~$ rvm install 1.8.7
bash: /home/kevinwmerritt/.rvm/scripts/manage: Permission denied

The .rvm folder appears in my home directory and the bash scripts initialize rvm successfully.

Using sudo yields the following:

sudo rvm install 1.8.7
sudo: rvm: command not found

I am new to Ubuntu.

Answer 1

If you did a single-user install of RVM do not use:

sudo rvm install 1.8.7

RVM creates its own sandbox in ~/.rvm which does not need root privileges ever. At NO time do you need to use sudo before rvm . sudo will only screw up everything.

Use an unadorned rvm install 1.8.7 or rvm install 1.9.2 or any other version of Ruby known to RVM. You can see the list it knows about using rvm list .

Answer 2

I am running into the same exact problem. I compared it against another installation of rvm on a different box that is working and noticed the permission for "manage" is different.

The box that is working:

-rwxr-xr-x  1 deployer deployer 59002 2011-05-19 22:56 manage

The box that is not working:

-rw-r--r--  1 deployer deployer 59076 2011-05-22 22:12 manage

I did a chmod 755 manage and that seems to have fixed it. I installed rvm the same way on both boxes, not sure why there's a difference.

You can try chmod 755 /home/kevinwmerritt/.rvm/scripts/manage and see if that resolves it
