Python at Synology, how to get Python3 modules installed and where is Python2.7 installed?

I'm not sure you can remove Python 2 altogether, but you can install Python 3 and evoke it specifically instead of Python 2.

First, make sure Python 3 is Installed: Log into your Synology via the web administration and in the 'Package Center' make sure 'Python 3' is installed. (You will find it under 'Developer Tools' within the 'Package Center')

Next, specifically evoke Python 3 by simply calling python3

You could also try using the locate command on your Synology to find the exact location of Python 2. To do this enter the following on your Synology:

ipkg update
ipkg install mlocate

And here is a tutorial on how to use the command: http://www.thegeekstuff.com/2012/03/locate-command-examples/

Good luck!

Also, If you don't have luck on Stack Overflow I'd run over to the Synology Forums for help as well: https://forum.synology.com

  • (1)install python2.7 and python3.5 from DSM packages
  • (2)ssh login & sudo -i
  • (3)run python and run python3, if both work go next.
  • (4)run pip -V should return pip 10.0.1, it is for python2.7
  • (5)run pip3 -V return "command not found", ..because the path is not right.
  • (6)try /volume1/@appstore/py3k/usr/local/bin/pip3 -V,
             if sucess. go next. now you can install module for python3,
             it's different path depends on your system, command for example:
             /volume1/@appstore/py3k/usr/local/bin/pip3 install numpy should be work!
  • (7)for convenient, shorter command is good for use,so go next step:
             sudo vi .profile, (or .bashrc for specific user login)
  • (8)add alias at the end:
             alias pip3='/volume1/@appstore/py3k/usr/local/bin/pip3'
  • (9)source .profile or sudo reboot
  • (10)test pip3 -V, should work for python3.x

    Ok, many thx for the replies, I solved it with:

    1. Confirmed that Python 2.7.9 is installed by default in Synology DSM 5.2 (and not visible in package center).

    2. I was able to add modules to Python3 by specifically evoking the pip module installation for Python3 using this command:(thx to this Q&A)

      /volume1/@appstore/py3k/usr/local/lib/python3.5/site-packages/pip install tweepy

    (installing the tweepy module in this case)

    And FYI the full command overview:

    (And I uninstalled the SynoCommunity Python3 package again and now use the DSM package center Python3 version)
