Bundle install: ERROR: Failed to build gem native extension. nio4r gem

Question

I\'m currently working on a project using:

• rvm 1.26.11
• ruby 2.2.1p85

I tried to run bundle install but keep getting the follow

Answer 1

I solved it with:

sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev
rvm use 2.0.0
Reboot pc

If I run rails -v shows me:

• Rails 3.2.17

And now I can make Bundle install

I think the rails version was in conflict. I don't know why, maybe anyone can explain me.
