gem安装mysql2时出错

Question

Hello i am having trouble installing mysql2 gem. The first error i was getting was mysql client is missing. I have fixed this with the following

gem install mysql2 -- '--with-mysql-dir="C:\Program Files\MySQL\MySQL Server 5.7"'

I then get the message that is missing mysql.h

gem install mysql2 -- '--with-mysql-dir="C:\Program Files\MySQL\MySQL Server 5.7" --with-mysql-config="C:\Program Files\MySQL\MySQL Server 5.7\bin"'

I have tried \\bin and \\include \\lib. i have tried different permutation of the last with-mysql to try and find the mysql.h and have been unsuccessful.

Any help will be greatly appreciated.

Thanks.

Not sure if this info is needed but just in case.
