Error While Install Gem

Nabusman

6/2/2009 7:21:00 PM

I am trying to install Mechanize on a WinXP machine, and I am getting
this error:

ERROR: Failed to build gem native extension

ruby extconf.rb install mechanize
extconf.rb:3:in ``': No such file or directory - uname -p
(Errno::ENOENT) from extconf.rb:3

Googling results only in solutions for linux distros... on linux the
problem is that the ruby development libraries are not installed, where
am I supposed to find these for Windows? On OS X i would have typed sudo
apt-get dev-1.8 or something, but what do I do on WinXP?

I think this went away with RubyGems 0.9.5

As did this.

I suspect that either your ruby or your RubyGems versions are too old
and you should upgrade. Currently RubyGems is at 1.3.4

What do:

ruby -v

and

gem env

say?

Yup, that solved it, thanks. What is weird is that the
one-click-installer puts such an old version of RubyGems.

Thanks,

The latest one-click is newer than ruby 1.8.6p111, you either found an
old version or installed it a long time ago.
