I am installing eHMP on Centos 7. Centos 7 has ruby 2.0 out of box, thus the install
chef-client -o workstation –config ~/Projects/vistacore/.chef/knife.rb
rb-notify version 0.10.0 needs Ruby 2.2.2 or newer
Following the instructions at https://noobient.com/2019/02/12/installing-rvm-and-ruby-on-centos-7/ I got ruby 2.7 installed. However
sudo chef-client -o workstation –config ~/Projects/vistacore/.chef/knife.rb
fails with the same error.
shows that rvm has no effect on sudo. I am still running the script against Ruby 2.0
Supposedly I can sudo and install rvm there, but rvm complained and suggested me to use rvmsudo instead. Then I tried it, rvmsudo doesn’t carry over my environment, even $HOME, thus the script still fails.
After searching for awhile I found a walkaround
rvmsudo bash -c “HOME=$HOME; exec bash” chef-client -o workstation –config ~/Projects/vistacore/.chef/knife.rb
This gets the home directory passed to the script, now the script is complaining
STDERR: ERROR: While executing gem … (OptionParser::InvalidOption) invalid option: –no-rdoc
The script was pretty old, I know. I have no time to fix the script, so I need to downgrade the ruby version. After testing for each version I settled for 2.3.
rvm install 2.3
rvm use 2.3 –default
sudo gem update –system 2.3
Now the script runs successfully.
