Error installing mysql2: Failed to build gem native extension

Question

I am having some problems when trying to install mysql2 gem for Rails. When I try to install it by running bundle install or gem install mysq

Answer 1

I had this issue on Windows 7. This is apparently an incompatibility issue and the solution is as follows:

Download the libmySQL.dll file from an older InstantRails installer. It is available from the InstantRails GitHub repo.

Next, copy that file into your Ruby/bin folder.

Now, you are good to go ;)
