As part of a project we’re working on, we needed to install the BOSH CLI on a Digital Ocean droplet running CentOS 7. The directions at bosh.io provided a list of all the packages that needed to be installed prior to installing the gem:
yum install gcc ruby ruby-devel mysql-devel postgresql-devel postgresql-libs sqlite-devel libxslt-devel libxml2-devel yajl-ruby
After installing all of these I still had an error when I attempting to install the BOSH CLI gem:
Running patch with /usr/local/share/gems/gems/nokogiri-22.214.171.124/ports/patches/libxml2/0001-Revert-Missing-initialization-for-the-catalog-module.patch... Running 'patch' for libxml2 2.9.2... ERROR, review '/usr/local/share/gems/gems/nokogiri-126.96.36.199/ext/nokogiri/tmp/x86_64-redhat-linux-gnu/ports/libxml2/2.9.2/patch.log' to see what happened. *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.
I ran into a similar issue on Mac OS X – I need to install
nokogiri. Fortunately, that seems a little more straightforward on CentOS. If you do a search for
nokogiri packages you will come up dry:
~# yum search nokogiri Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.thelinuxfix.com * extras: mirrors.lga7.us.voxel.net * updates: mirrors.lga7.us.voxel.net Warning: No matches found for: nokogiri No matches found
The reason is that you need to install the appropriate EPEL (Extra Packages for Enterprise Linux) package:
yum install epel-release
This is actually very quick as the package is only about 14k.
After you have installed EPEL, you will be able to find the appropriate
~# yum search nokogiri ... ===================== N/S matched: nokogiri ====================== rubygem-nokogiri-doc.x86_64 : Documentation for rubygem-nokogiri rubygem-nokogiri.x86_64 : An HTML, XML, SAX, and Reader parser Name and summary matches only, use "search all" for everything.
yum install rubygem-nokogiri.x86_64
Then install the BOSH CLI:
gem install bosh_cli --no-ri --no-rdoc
This will take a five or so minutes. To test the installation, check the version:
~# bosh version BOSH 1.2881.0
- Everything here was done as
- If you run
gem install bosh_cli bosh_cli_plugin_micro --no-ri --no-rdocinstead of just
gem install bosh_cli --no-ri --no-rdocthe installation will take much longer and may appear to initially freeze.
