Error installing mysql2 gem ( windows 8 ) - mysql

Question

i'm currently trying to install the mysql2 gem on a windows 8 platform. I have installed the mysql_connector and used the following code below. But still seem to be getting the same error. What steps should I take to address this issue.
C:\Users\Samuel>gem install mysql2

Answer 1

Download the 32-bit Zip Archive of connector from here. Then copy it at the root of your C drive for ease of access so that your connector folder path will be something like this
C:\mysql-connector-c-6.1.3-win32\
Now copy this line of code to your cmd and execute (remember to change the connector version number with your one)
gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:/mysql-connector-c-6.1.3-win32/"'
After trying for a long time I successfully installed mysql2 gem in both of my 32 and 64 bit windows 7 in this way. Cheers!

Answer 2

I have been using windows 7 and have faced the similar error and ended up in using mysql gem instead of mysql2. And apart from this, many errors kept rising. That made me to shift to linux, and after that no such problems poked me.
I had made a ferocious attempt to include mysql2 fem using windows for a whole day, but the results were not fruitful. If you are really keen to solve, go through these links (link1 and link2). Maybe you will find something useful.

Answer 3

This is how I Installed my mysql2 gem on windows 8.
c:\DevKit>gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:\Ruby193\my
sql-connector-c-6.1.3-win32/"'
