Hi all. Almost done setting up rails on mac. Got to installing rails and I got: ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
It's myhome workstation.. I definitely have permissions.. I am the only user. I'm on Yosemite 10.10.5 Any help appreciated! thanks
Hey Cindy,

Just installed on OSX Yosemite 10.10.5 using wine.
Even though it's your home system, you probably don't have the user permission required to do the install. It's kind of like installing from a disk image, where you need to enter your admin password.
Try prefixing the install command with sudo (this is telling the console that you are the 'Super user'. It will ask you for your password (this will be your admin password for you system). You probably won't see anything being typed (this is normal), but it is there.
This should solve that error. :)
well, I had some concerns on doing this because of some threads on stack_overflow but I took a gamble. Here's how far I got. What's next?''sudo gem install rails --version 5.0.0Password:Fetching: i18n-0.7.0.gem (100%)Successfully installed i18n-0.7.0Fetching: thread_safe-0.3.5.gem (100%)Successfully installed thread_safe-0.3.5Fetching: tzinfo-1.2.2.gem (100%)Successfully installed tzinfo-1.2.2Fetching: minitest-5.9.0.gem (100%)Successfully installed minitest-5.9.0Fetching: concurrent-ruby-1.0.2.gem (100%)Successfully installed concurrent-ruby-1.0.2Fetching: activesupport-5.0.0.gem (100%)ERROR: Error installing rails: activesupport requires Ruby version >= 2.2.2.''
I didn't realize your were doing the Rails 5 Course. Though I'm not 100% sure, it looks like you need to upgrade your Ruby to the needed version.
Try upgrading your Ruby to 2.2.2. There are instructions here (scroll to the bottom and sub the 2.1.1 with 2.2.2). Then try the Rails install again.

Jason Anders , yeah, we're generally trying to encourage students to use RVM so that they have an easier time installing and managing their gems, and don't have issues with things like sudo.

Cindy L Francies , were you following the directions in our installation workshop? If not, I would recommend using those; it'll give you a solid, upgradeable Ruby and Rails install, and we'll have an easier time helping you troubleshoot.

Yeah, I followed the video. Just didn't work. I wanted to hold out and not do the SUDO because it was recommended to not do that on Stack Overflow.. perhaps you can comment ? (I did eventually relent and do it.. seems to be ok now.)
Cindy L Francies on what step of the installation workshop did it fail? Can you reattempt the step(s), and copy and paste the output?
I believe it is working now.. at least installed correctly. the errors were what I mentioned above:
- ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
- When i did the SUDO suggestion it got to the point where it failed because I didn't have Ruby 2.2.2- which I installed per above. Thanks
