The following Ruby gem installation without sudo used to work back in the day:

xcode-select --install

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

export PATH=/usr/local/bin:$PATH

launchctl setenv PATH “/usr/local/bin:$PATH”

brew install ruby

gem install jekyll

But now on the last step, I get:

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

I have tried this solution - https://gist.github.com/DirtyF/5d2bde5c682101b7b5d90708ad333bf3. And, it sort of worked, but now my $PATH is messed up. echo $PATH returns - /Users/username/.rbenv/shims:/Users/username/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin.

I have fully removed rbenv and cleared .bash_profile. Now my $PATH looks like so /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin what gets me back to the point one:

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

Can anyone share a correct up-to-date way to install Ruby gem without using sudo and messing up the $PATH?

Don't install ruby with homebrew if you are going to use a ruby version manager, i.e. rbevn.

I would at this point recommend brew uninstall ruby

Then use rbenv if you already have it working to install your ruby version.

But if you are confused and not sure what you're doing, you might wanna consider using RVM instead of RBENV as the install/setup is easier.

If so see How do you uninstall rbenv on OSX?

Then see https://rvm.io/rvm/install

Looking at your gist
echo "export PATH=$HOME/gems/bin:$PATH" >> ~/.bashrc

You may need to edit your ~/.bashrc and remove that export line

You will probably want to close and reopen your terminal before doing any of the above. Anything that makes changes to ~/.bashrc won't take effect until you restart your terminal

Thanks for the helpful link lacostenycoder. I have managed to get Ruby gems installed without sudo the following way:

xcode-select --install

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install rbenv

echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

rbenv install 2.5.1

rbenv global 2.5.1

gem install jekyll
