ERROR: Failed to build gem native extension when installing Rails 4.2.4. Says it "Could not find 'mini_portile2'"

[ma...@orussa.com]

I'm on CentOS 7 with a cPanel installation. I've have rbenv installed with Ruby 2.2.4 and I'm getting an error trying to install Rails 4.2.4. Here's the output:

gem install rails -v 4.2.4

So it looks like I have mini_portile2 installed, but Nokogiri can't find it?

I've tried installing different versions of Ruby (2.3.0) and Rails (4.2.5), but I get the same error. I was able to install Rails under another domain/user account on the same VPS server at the beginning of the year. Perhaps I need specific versions to install properly?

Hi,

Thanks for asking this question. I'd recommend you *uninstall* mini_portile2 v2.1.0 and see what happens.

The longer story here is that rubygems only enforces version checks at runtime, not at installation time, and mini_portile2 is an installation-time dependency.

Bundler would help with this, but it doesn't look like you're using Bundler.

I meant to use bundler. I'm trying to have a fairly simple and common Rails installation.

After uninstalling the mini_portile2 gem I get the same error. It just re-installs mini_portile2 and fails in the same place. I'll probably start over with rbenv if this isn't working.

gem install rails -v 4.2.5

OK, just to make sure we're communicating well with each other ...

In your original post, you showed that you have both mini_portile2 v2.0.0 and v2.1.0 installed. The error message shown is consistent with v2.1.0 being used, instead of v2.0.0.

Can you please confirm that you uninstalled *both* v2.0.0 and v2.1.0 before proceeding?

If so, can you please provide the contents of your `mkmf.log` file?

Thank you for being very specific. I ran

gem uninstall mini_portile2

which removed all versions:

kuronekocon@kuronekocon.com [~]# gem list

So after uninstalling mini_portile2 I installed bundler:

kuronekocon@kuronekocon.com [~]# gem install bundler
Successfully installed bundler-1.11.2
1 gem installed

Following the rbenv documentation I should check the location of where gems are being installed:

kuronekocon@kuronekocon.com [~]# gem env home
/home/kuronekocon/ruby/gems

I noticed this doesn't match the example given in the docs: # => ~/.rbenv/versions/<ruby-version>/lib/ruby/gems/...

Should my gem location be inside the .rbenv directory? Is this a potential source of errors and something I need to figure out before continuing?
