Problem Installing Rails


Could anyone help me with installing rails? I’m on Step 2 of the “Your First Rails Application.” When I type in gem install rails I get the following message:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

In the previous lesson, I had followed the steps an entered the following commands:
rbenv install 2.5.3 --verbose and rbenv global 2.5.3

But when I type ruby -v I get the message: ruby 2.3.7p456 (2018-03-28 revision 63024) [universal.x86_64-darwin18]

Also, I don’t know if this effects anything, but I’m using Iterm2 on a Macbook Pro


Are you using rbenv to install your rubies?

What are the contents of your ~/.bashrc or ~/.bash_profile files?


Sorry, rookie here. How do I access those files? I typed them in but it says zsh: no such file or directory


Did you follow the installfest instructions?


I just followed all the instructions in the “Installations” section of TOP. I just tried it again and one thing I did notice is that instead of saying

# Load rbenv automatically by appending 
# the following to ~/.bash_profile: 

it says

# Load rbenv automatically by appending 
# the following to ~/.zshrc: 

So in the next line (echo 'eval "$(rbenv init -)"' >> ~/.bash_profile), I tried replacing the ~/.bash_profile part with ~/.zshrc, but still no luck


If you are using zsh you will need to do the following

It gives you the line to add to your zshrc. That should get you going.


Thank you very much. Everything works fine now.
