gem install datamapper error

Question

I'm trying to install datamapper and I'm getting this error:

Whirlwind:Desktop AGreen$ gem install data_mapper
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied - /Users/AGreen/.rvm/gems/ruby-1.9.2-p320/gems/bcrypt-ruby-3.0.1/.gitignore

I also tried to install it this way:

Whirlwind:Desktop AGreen$ gem install datamapper
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied - /Users/AGreen/.rvm/gems/ruby-1.9.2-p320/gems/bcrypt-ruby-3.0.1/.gitignore

Does anyone know how I can fix this?

Seems like a permission issue to me.

To check:

ls -l ~/.rvm

Should all belong to you.

To fix:

sudo chown -R AGreen /Users/AGreen/.rvm

You may also consider chown'ing your whole home directory.

If you're on linux, you'll need to prefix your command with sudo.

Try

sudo gem install data_mapper

I'm on a mac. I tried that too, for some reason it doesn't work – skyfaerie Oct 31 '12 at 21:33
yes. I just installed the dm-postgres-adapter gem. everything worked perfectly – skyfaerie Oct 31 '12 at 21:44
It strongly depends if RVM is installed in userspace or as root. As far as i see `/Users/AGreen/.rvm`, it's definitely a userspace installation. – phil pirozhkov Nov 03 '12 at 14:13
