It works for me so it's probably some dependency or environment issue:

[majormoses]

have you installed the packages outlined here: https://github.com/sensu-plugins/sensu-plugins-supervisor#installation

[shayangz]

strange. I have libexpat1-dev installed.

libexpat1-dev is already the newest version (2.1.0-7ubuntu0.16.04.2).

and the ruby versions:

ruby --version
ruby 2.2.7p470 (2017-03-28 revision 58194) [x86_64-linux-gnu]

and

ruby -v
ruby 2.3.4p301 (2017-03-30 revision 58214) [x86_64-linux-gnu]

Would having libxml2-dev installed have anything to do with this issue?

libxml2-dev is already the newest version (2.9.3+dfsg1-1ubuntu0.2)

[majormoses]

I have that installed as well. We definitely will need to do some work to figure out the dependencies (likely they are outside of ruby). If I have some time this weekend I will work on re-producing this.

[majormoses]

@shayangz I tried reproducing this in docker and was unable to from some quick tests. I created this to make it a bit easier to test: https://github.com/majormoses/sensu-plugin-install-test

Here are some quick setup instructions (yes I will create a readme later):

1. create a Gemfile in /app (it is .gitignored so it can be reused for testing any gem):

$ cat app/Gemfile 
source 'https://rubygems.org'

gem 'sensu-plugins-supervisor'

2. docker build:

docker build .

3. jump into the container and set any required packages to install (replace the image id with the one created in previous step):

$ docker run -e PACKAGES='build-essential,libexpat1-dev' d03f294ac7b9 ./install_packages.sh

If you can report back if you can get something to fail with this setup this would help me determine where the issue is.

[shayangz]

Thanks for the test repo! Helped a ton.

I have posted the repro here: majormoses/sensu-plugin-install-test#1

It looks like the ruby2.3-dev package is the curlpit. I couldn't get the repro working with the 2.3-slim image so changed it to ubuntu:16.04.

[majormoses]

Can you put a PR together here to document the need of ruby2.3-dev to be installed?

[shayangz]

I am not sure how to solve this problem actually.

The root cause is that the ruby-xmlparser prior to version 0.7.3 fails to build with a new version of Expat (2.2.0). Version 0.7.3 addresses this issue but it's not published to rubygems.

This issue was hidden prior to PR #18.

Any idea on how to go about fixing this?
