copied!<p>I had the original issue reported in this question, "<strong>mkdir: cannot create directory `/usr/local/rvm': Permission denied</strong>" when trying to install rvm.</p> <p>This is my scenario and how I solved it - maybe this will help others with this same issue.</p> <p>I have Ubuntu 11.04 installed on a laptop, I only have 1 user, the one I created at install time, named nathan. When I would try to install rvm as nathan, the rvm installer saw me as root and kept trying to install rvm globally, but since I wasn't really root, it couldn't get access to create directories in /usr/local/rvm.</p> <p>I'm far from an expert with Ubuntu, so I'm sure there are easier/better ways to accomplish the things I did (and I would love to learn about them), but this worked for me:</p> <ol> <li>I created a new user called rubydev</li> <li><p>I logged in as rubydev, opened a terminal and typed:</p> <pre><code>rubydev~$ bash < <(curl -B http://rvm.beginrescueend.com/install/rvm) </code></pre></li> <li><p>rvm installed correctly and I logged out of rubydev</p></li> <li>Signed back in as nathan, opened a terminal and typed "su" (you could do all this with sudo, I am lazy)</li> <li><p>After successfully getting root, I typed the following commands:</p> <pre><code>root: /home/nathan# cp -R /home/rubydev/.rvm . root: /home/nathan# chown -R nathan .rvm root: /home/nathan# chgrp -R nathan .rvm root: /home/nathan# exit nathan~$ echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile nathan~$ echo 'export rvm_path="/home/nathan/.rvm"' > ~/.rvmrc nathan~$ source .bash_profile </code></pre></li> <li><p>At this point, rvm was correctly installed under my home directory. To verify I typed:</p> <pre><code>nathan~$ type rvm | head -1 rvm is a function (if you don't get this response, something else is wrong) </code></pre></li> <li><p>Read the notes and installed any dependencies</p> <pre><code>nathan~$ rvm notes </code></pre></li> <li><p>I installed some rubies</p> <pre><code>nathan~$ rvm install 1.8.7-head nathan~$ rvm install 1.9.2-head </code></pre></li> <li><p>Verified install</p> <pre><code> nathan~$ rvm list rvm rubies ruby-1.8.7-head [x86_64] ruby-1.9.2-head [x86_64] nathan~$ rvm use 1.9.2 using /home/nathan/.rvm/gems/ruby-1.9.2-head nathan~$ rvm list rvm rubies ruby-1.8.7-head [x86_x64] => ruby-1.9.2-head [x86_x64] </code></pre></li> <li><p>Finally, I edited the preferences on the terminal itself to ensure the "Run command as as login shell" under the "Title and Command" tab was checked. It seems .bash_profile isn't otherwise processed.</p></li> <li><p>I removed the rubydev user I created in step 1.</p></li> </ol> <p>With all of that, I have a working rvm under Ubuntu 11.04 using my preferred username.</p>
