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.

sudo -i

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.

-sh: sudo: not found

ipkg_conf_init: Failed to create temporary directory '(null)': Permission denied

ssh admin@synonlogy

sudo -i

sudo -su

Just logon into synology over ssh to user admin right, then
sudo -i

and here what i get after success login into root:

root@x:~# curl -k https://bootstrap.pypa.io/get-pip.py | python3

/usr/local/bin

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:

.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
