Install Slanger on Ubuntu VPS

Hi there,

Can someone help me with installing Slanger on my Ubuntu VPS. I get stuck on gem install slanger

I’ve got the error:

    Unable to resolve dependencies: slanger requires rack (~> 1.4.5); thin requires rack (~> 1.0); sinatra requires rack (~> 1.5); rack-protection requires rack (>= 0)```

Thanks for your help!

When I need to install new gems I start off by installing a few packages that can be helpful:

apt-get update;
apt-get install ruby-dev build-essential

If you installed gems like sinatra or rack from the Ubuntu repositories they may be too old to support the gem you are now trying to install. I would then recommend removing any packages like ruby-sinatra and installing them instead via gem install sinatra
