I have tried in the last week with a fresh copy of Linux mint 18 Ubuntu 16.04 and fedora 24?(the latest one). All 3 give me the error with debug inspector.

Make sure that `gem install debug_inspector -v '0.0.2'` succeeds before
bundling.

Answer
This can help you:
If you have issues, first make sure you have all the tooling necessary to compile C extensions:
sudo apt-get install build-essential patch
It’s possible that you don’t have important development header files installed on your system. (This has never happened to me personally, but I have it on good authority that otherwise good and noble Ruby developers run into this.) Here’s what you should do if you should find yourself in this situation:
sudo apt-get install ruby-dev zlib1g-dev liblzma-dev
Please report it as a bug if this doesn’t work for you (see Getting Help for details).
