Installing pip on a DSM/Synology

I've been working on a program using python 3 for the last few months. I've been testing it for some time now and it seems to work as it should. So I've tried to get it up and running on a DSM/Synology(Model: DS209+, Version: DSM 4.2-3259). Sadly I don't know anything about this environment. So I installed python3 (3.3.2-0005) from the Synology Package Center and got it working. Running my code works. The only problem is, that my program uses the "requests" library. However I just can't get pip running. For installing pip, I tried to use the following line in PuTTY.

curl -k https://bootstrap.pypa.io/get-pip.py | python3

I'd expect pip to download/install and use it to get the requests library. But then this happens and I have don't know what I did wrong:

The directory '/var/services/homes/admin/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

It seems like using sudo -H would fix the issue. However I have no idea how to do that and where to start. Googling the issue didn't help much either because the things I found where either too vague for me to understand or they had this issue with pip already installed. I hope this question isn't too vague either.

My synology box only has Python 3.4.1 available, very old box that I have not updated.

using get-pip.py does not work because that currently needs python 3.5 or greater. However, the following did work:

python3 -m ensurepip --default-pip

I installed pip following this method:

wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py

However, some libraries won't install as Synology's latest version of Python is by now 3.5. If this can be of some use for everyone, I used easy.install package found in @appstore/py3k/usr/local/bin to install pip packages; some of them (like telepot) won't install with pip for some aiohttp issues.

Login to DSM with root permission via SSH/Telnet:

  • SSH to your Synology device using your admin account: ssh [email protected]
  • Run sudo -i to switch to root.

After successfully logging in as root, you will have the permissions needed to install pip:

When using a new venv pip is available automatically. For example:

user@host:~$ python3 -m venv env
user@host:~$ . env/bin/activate
(env) user@host:~$ pip --version
pip 7.1.2 from /volume1/homes/user/env/lib/python3.5/site-packages (python 3.5)

After that you can upgrade pip to the current version:

user@host:~$ pip install --upgrade pip
...
Successfully installed pip-18.0

This also has the advantage that installing packages with pip cannot break the system python.

To automatically activate your environment you can create a .profile:

user@host:~$ touch ~/.profile
user@host:~$ chmod u=rwx ~/.profile

and then make the content of it look like this:

#!/bin/sh
. env/bin/activate

Like @hoefling already mentioned, it's a privilege issue.

Login via SSH

ssh user@synology

and enter user password.

Get admin privileges

sudo su

and enter sudo password.

Get installation file

wget https://bootstrap.pypa.io/get-pip.py

and execute installation file.

python get-pip.py

Let me know if it worked for you.
