Installing Rails on Mac OS fails with several errors

Question

I am trying to install Rails on my Mac OS v10.10.4 system, and it fails when I run brew install rbenv ruby-build . The error is:

Error: Permission denied - /usr/local/etc/openssl
Warning: Bottle installation failed: building from source.

At the end of the process it says:

installing man3/d2i_SSL_SESSION.3ssl
i2d_SSL_SESSION.3ssl => d2i_SSL_SESSION.3ssl
installing man3/ssl.3ssl
Cannot create directory /usr/local/etc/openssl: Permission denied

Here is the complete log of all what I tried during this attempt:

I have looked at the folllowing links so far:

• http://rubyonrails.org/download/
• Installing gem or updating RubyGems fails with permissions error
• https://github.com/sstephenson/rbenv/
• https://gorails.com/setup/osx/10.10-yosemite
• Missing the OpenSSL lib?

Answer 1

Run this command first

sudo chown -R <your username>:admin /usr/local

Replace <your username> with whatever your username on your mac is. So, in my case, I would run

sudo chown -R Adrian:admin /usr/local

Then try installing rbenv and ruby-build.

Your problem is most likely caused by the use of package installers (.pkg files) as they tend to create files as root in places where they shouldn't.

Note: you can find out your username by running whoami

Answer 2

I finally used this tutorial Setup Ruby On Rails on Mac OS X 10.11 El Capitan after updating my mac to EI caption few months back and this worked.

Here is log from console it will explain all what happens. And how finally I got to run my first ruby application. There are several mistakes that I made which a beginner might will, but I finally nailed it. Here is how it looks.
