sensu-plugins-memcached's Issues

Dependabot can't resolve your Ruby dependency files

Dependabot can't resolve your Ruby dependency files.

As a result, Dependabot couldn't update your dependencies.

The error Dependabot encountered was:

Bundler::VersionConflict with message: Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler (~> 1.7)

  Current Bundler version:
    bundler (2.2.15)

Your bundle requires a different version of Bundler than the one you're running.
Install the necessary version with `gem install bundler:1.17.3` and rerun bundler using `run.rb _1.17.3_`

If you think the above is an error on Dependabot's side please don't hesitate to get in touch - we'll do whatever we can to fix it.

I use the embedded ruby from sensu and do not have another version of ruby installed.

plugin install fails on first run

This plugin fails on the first run, but a subsequent attempt to install is always successful. All dependencies are installed, like libsasl, etc.

The following output is from sensu-install:
