问题:

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:

Installing gem or updating RubyGems fails with permissions error

Missing the OpenSSL lib?

回答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

回答2:

If a home brew install is causing problems your first reflex should be to run

brew doctor

This should diagnose most issues and even suggest remedies (such as the ones mentioned by other answers)

回答3:

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.
