Failing to install mechanize

Ruby
1

Hello Team,

I am trying to install mechanize but it is failing. Any help will be
appreciated.
Here are the details:

OS: Red Hat Enterprise Linux Workstation release 6.2 (Santiago)
Ruby:
ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

It complains that that library:* libxslt is missing.* However, the
library
IS installed:
#* rpm -qa | grep -i libxslt*
libxslt-python-1.1.26-2.el6.x86_64
libxslt-1.1.26-2.el6.x86_64

Also, if I try to install it it states that it is already installed:

yum install libxslt
Setting up Install Process
Package libxslt-1.1.26-2.el6.x86_64 already installed and latest version
Nothing to do

Now the errors from gem:

gem install mechanize

/usr/local/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your
ruby.
Building native extensions. This could take a while…

Gem files will remain installed in
/usr/local/lib/ruby/gems/1.9.1/gems/nokogiri-1.5.0 for inspection.
Results logged to
/usr/local/lib/ruby/gems/1.9.1/gems/nokogiri-1.5.0/ext/nokogiri/gem_make.out

When I try to install *psych *or yaml I get the same errors listed
above.

Thank you

Hi,

I would advise you to unistall your ruby installation and install rvm
first and go from there.

When you see errors or notifications like what you’re getting, it means
that you need the development packages installed. You only have the
runtime packages, and those don’t include everything that is required to
compile a native extension such as mechanize.

I believe the package you need to install is libxslt-devel.

You can try to install all the package containing this word

yum install libxslt*

OK, I got rvm installed. It also looks like it installed ruby.
But, how do I invoke ruby installed by rvm? When I type: ruby -v, I
get
an error.

rvm install 1.9.3

Great!

Thank you

Check if you have got everything installed for rvm by typing rvm
requirements

Sorted?

Will do.

Thank you for your help

Hi,

Type in rvm list first to see what Ruby version you have got installed.
Then rvm use 1.9.3 --default
