状況
PythonでMySQLの設定をしていて以下のコードを実行した。$ sudo pip3 install flask-mysqldb
そしたら OSError: mysql_config not foundと言われてしまった。

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

解決方法
下記Stack Overflowを参考にした。mysql_configをインストールしないといけないらしい。
mySQLdb is a python interface for mysql, but it is not mysql itself. And apparently mySQLdb needs the command 'mysql_config', so you need to install that first.
Can you confirm that you did or did not install mysql itself, by running "mysql" from the shell? That should give you a response other than "mysql: command not found".
Which linux distribution are you using? Mysql is pre-packaged for most linux distributions. For example, for debian / ubuntu, installing mysql is as easy as
なので以下のコードを実行したらOK
$ sudo apt-get install mysql-server
$ sudo apt-get install libmysqlclient-dev
もう一度
$ sudo pip3 install flask-mysqldb
を実行すればインストールできた。
