Dependencies
teos_cli has both system-wide and Python dependencies. This document walks you through how to satisfy them.
System-wide dependencies
teos_cli has the following system-wide dependencies:
python3version 3.6+pip3opensslversion 1.1+
Checking if the dependencies are already satisfied
Most UNIX systems ship with python3 already installed, whereas OSX systems tend to ship with python2. In order to check our python version we should run:
python --version
For what we will get something like:
Python 2.X.X
Or
Python 3.X.X
It is also likely that, if python3 is installed in our system, the python alias is not set to it but instead to python2. In order to check so, we can run:
python3 --version
If python3 is installed but the python alias is not set to it, we should either set it, or use python3 to run teos_cli.
Regarding pip, we can check what version is installed in our system (if any) by running:
pip --version
For what we will get something like:
pip X.X.X from /usr/local/lib/python2.X/dist-packages/pip (python 2.X)
Or
pip X.X.X from /usr/local/lib/python3.X/dist-packages/pip (python 3.X)
A similar thing to the python alias applies to the pip alias. We can check if pip3 is install by running:
pip3 --version
And, if it happens to be installed, change the alias to pip3, or use pip3 instead of pip.
Installing the dependencies
python3 ca be downloaded from the Python official website or installed using a package manager, depending on your distribution. Examples for both UNIX-like and OSX systems are provided.
Ubuntu
python3 can be installed using apt as follows:
sudo apt-get update
sudo apt-get install python3
and for pip3:
sudo apt-get install python3-pip
pip install --upgrade pip==9.0.3
OSX
python3 can be installed using Homebrew as follows:
brew install python3
pip3 will be installed alongside python3 in this case.
Python dependencies
teos_cli has the following dependencies (which can be satisfied by using pip install -r requirements.txt):
