Python e PIP e Mysql

[marcoqf]

Buongiorno.
Sto cercando di installare su Synology DS215j una libreria di Python (mysqlclient) che mi permette di connettermi al DB Mysql

1) Ho installato Python 3.5 dal package manager

2) Poi mi sono collegato in SSh alla Synology Station come admin --> sudo -i

3) Installato Pip3
curl -k https://bootstrap.pypa.io/get-pip.py | python3

Ho Poi verificato quali pacchetti di Python fossero nel sistema
--> /volume1/@appstore/py3k/usr/local/bin/pip3 list
Package Version
pip 19.1.
setuptools 41.0.1
wheel 0.33.4
------------------------------------

4) Ho poi provato ad installarel --> mysqlclient
/volume1/@appstore/py3k/usr/local/bin/pip3 install mysqlclient

Collecting mysqlclient
Using cached https://files.pythonhosted.org/packages ... st1.tar.gz


Ma ho un errore ch mi impedisce di continuare

ERROR: Complete output from command python setup.py egg_info:
ERROR: /bin/sh: mysql_config: command not found
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-install-kfd9_v0o/mysqlclient/setup.py", line 16, in <module>
metadata, options = get_config()
File "/tmp/pip-install-kfd9_v0o/mysqlclient/setup_posix.py", line 51, in get_config
libs = mysql_config("libs")
File "/tmp/pip-install-kfd9_v0o/mysqlclient/setup_posix.py", line 29, in mysql_config
raise EnvironmentError("%s not found" % (_mysql_config_path,))
OSError: mysql_config not found
----------------------------------------
ERROR: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-kfd9_v0o/mysqlclient/

PURTROPPO non so cosa fare, voi avete qualche suggerimento?

Grazie
