Unable to install rails - & ldquo; The file exists @ dir_s_mkdir & rdquo; Error

advertisements

I have had rails installed and almost working. Was working on a solution to another problem with I accidentally closed the bash window. So I reopened it, and now I am unable to use rails at all and it's telling me that rails isn't installed. So I ran gem install rails --no-ri --no-rdocand now I get the following:

ERROR:  While executing gem ... (Errno::EEXIST)
File exists @ dir_s_mkdir - /usr/local/Cellar/ruby/2.1.1_1/lib/ruby/gems`

How do I correct this error?


I just removed the broken gems, site_ruby and vendor_ruby symlinks from the /usr/local/Cellar/ruby/2.1.1_1/lib/ruby/ folder and now everything seems to work fine.
