Setup MacOS 10.12 Sierra Discussion

Chris Oliver asked in General

Thanks for posting this, Chris. Did you face any issues with Nokogiri when installing the Rails gem?


I haven't actually tested this personally just yet. :) I've got reports it worked great. Are you having issues with it?

I experienced issues similar to this when installing Nokogiri:

xcode-select --install

prior to installing Nokogiri worked for me.

I have problem with 10.12 sierra :( rbenv not command found
If you want install RoR on macOS 10.12 Sierra you must update Command Line Tools

Иван Лещинский Иван Лещинский

This commands helped me:
`brew install libxml2 libxslt`
`gem install nokogiri -v '' -- --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2`


this might be preferred though
brew unlink xz; bundle install; brew link xz

Guys, I have a problem. When I run rbenv install 2.3.1, it stops on this line.
^Cappleui-iMac:~ apple$ rbenv install 2.3.1
Downloading ruby-2.3.1.tar.bz2...
Installing ruby-2.3.1...

I installed Xcode not command line but I fully updated it.

Does anyone can help me?


Actually, it works. It requires some time. So never mind!


hello there,

I receive an error whenever I try to run the server or use the "rake db:create" command.
I'm using mysql db , tho


There's actually a bug right now (in the last 2 hours) with the thor gem causing problems in new apps. Try this:


When I try to run rbenv rehash, I get this error:

dyld: Library not loaded: /usr/local/opt/readline/lib/libhistory.6.dylib
Referenced from: /usr/local/bin/bash
Reason: image not found
Abort trap: 6

Not finding anything very helpful right now. Has anyone run into this issue? I just installed macOS Sierra and updated Ruby, Rails, rbenv...


My English is not so good but your explanation is very clear to me! thanks a lot!


I ran the command:

echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile

And now everytime I open a terminal window I am getting the below at the top of my window:

-bash: /Users/robertsaunders/.bash_profile: line 2: syntax error near unexpected token `source'
-bash: /Users/robertsaunders/.bash_profile: line 2: `if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi source /Users/robertsaunders/.bash_profile'

Please help!


After installing ruby the version doesn't see to update. does anyone have a suggestion? Running sierra 10.12.2

Audios-MacBook-Pro:shopify Audio$ rbenv install 2.2.5

Installing ruby-2.2.5...
Installed ruby-2.2.5 to /Users/Audio/.rbenv/versions/2.2.5\

Audios-MacBook-Pro:shopify Audio$ ruby -v
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]


it might be worth adding this to the tutorial-
this needs to be in the last line of ~/.bash-profile

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"


This helped a lot! I just wish there were an easy way to know if I've just installed the latest versions of everything


I had a problem in the Final Steps; i.e. running rails new myapp -d mysql. The problem was that mysql2 (0.4.5) was not built and installed. It asked me to run 'bundle install'. I then encountered another problem, ssl and encrypto libraries were not found in lib build path (it used /usr/local/Cellar/mysql/5.7.17/lib/). Setting up DYLD_LIBRARY_PATH won't work. To work around this, I copied all /usr/lib/*ssl* and /usr/lib/*crypto* to /usr/local/Cellar/mysql/5.7.17/lib/ and run 'bundle install' again and all worked. Just FYI and thanks.


Using `rbenv install --list`, the latest version I get is 2.4.0preview2. How does one get the latest stable build like you? Total newb, need some help, I went to the rbenv installation guide on github and followed their instructions. Can we only install what we see in the results from the `rbenv install -l` command?


What I usually do is I run "rbenv install 2.4.0" and it will say hey, this version is missing so update your ruby-build version and give you instructions on how to do that. Then running the install command should succeed then.


I had to run the rbenv commands with "sudo" otherwise it wouldn't even compile. Something about the -LD flags being wrong. That also forced "sudo" on the gem install command. But otherwise, everything went as advertised.
