Python3 can be easily installed on Synology DSM through Synology Installation Center but pip installation is skipped. The first method to install pip is to bootstrap the pip installer into an existing Python installation. The ensurepip package is aimed for it. It's available starting from Python version 3.4. As all pip components are a part of Python package, the internet connection is not required to install pip. The second method installs pip manually and it does request internet connection.

The method #1 is based on Synology DSM 6.2.2-24922 Update 4 and Python version is 3.5.1. Python 3.5.1 bin folder is /volume1/@appstore/py3k/usr/local/bin. Python 3.5.1 lib is located in /volume1/@appstore/py3k/usr/local/lib/python3.5 folder.

The method #2 is tried with Synology DSM 6.2.3-25426 Update 3 and Python version is 3.8.2. Python 3.8.2 bin folder is /volume1/@appstore/py3k/usr/local/bin. Python 3.8.2 lib is located in /volume1/@appstore/py3k/usr/local/lib/python3.8 folder.

1. Validate Python3 installation and version.

python3 -V

2. Install pip

Run pip installation with admin privilege. A running Synology user has to belong to the administrator group. There are 2 options to proceed: (1) run commands as sudo or (2) switch to root with sudo -i.

sudo python3 -m ensurepip

If you receive the message: /usr/local/bin/python3: No module named ensurepip, it means the ensurepip package is not available and you have to go with method #2.

  • Download package.

    wget -O /tmp/
  • Install package.

    sudo python3 /tmp/

3. Upgrade pip to the latest version.

Skip this step if it has been used the method #2.

You might need to add an option to limit pip installation version if your Python version is old one and reached end-of-life. For example, Python 3.5 is not supported anymore and the added option is "pip < 21.0".

sudo python3 -m pip install --upgrade pip

if your Python version is reached end-of-life.

sudo python3 -m pip install --upgrade "pip < 21.0"

4. Validate pip installation and version.

python3 -m pip -V

5. Install a package, for example, requests.

sudo python3 -m pip install requests
