问题
When trying to install gems using rvm i get this error
$ rvm gem install sproutcore
ERROR: While executing gem ... (Errno::EACCES)
Permission denied - /home/tee/.gem/specs
but it says on the rvm site that you should not use sudo so I'm not sure whats wrong with my setup
when i type $GEM_HOME it shows that the directory is pointing to the rvm dir
$GEM_HOME
bash: /home/tee/.rvm/gems/ruby-1.8.7-p302: is a directory
Any ideas what I'm doing wrong?
回答1:
There's a permission issue with your .gem folder. Make sure the owner is your current user.
sudo chown -R tee /home/tee/.gem
If it doesn't work, remove the .gem folder. It is automatically created when you update the gem cache.
Also, make sure you never used sudo with rvm.

I was having the same problem. I redid this command
user$ source ~/.rvm/scripts/rvm
from a new terminal window (as suggested when installing rvm and possibly overlooked when I was installing rvm) and things seemed to be fine after that
回答3:
http://rvm.io/set/gem/
or just
$ rvm <ruby_version> $ gem install sproutcode
This should definitely work.
回答4:
its probably not the correct way of doing things but I found that using rvmsudo resolved the issue, eg
rvmsudo gem install rails

I was having the same problem because the RVM was installed globally, in /usr/local/rvm , so it had no permission to install gems in ruby directory.
The workaround is to use Single User Installation, this will install your rvm in your user's home directtory(~/.rvm) so it will have all necessary permissions to install the gemsets and gems.
If you want to know the subject better read https://rvm.io/rvm/install . You will see that Single User Install is the recommended .
