# Dependencies
|
|
|
|
`pisa-cli` has both system-wide and Python dependencies. This document walks you trough how to satisfy them.
|
|
|
|
## System-wide dependencies
|
|
|
|
`pisa-cli` has the following system-wide dependencies:
|
|
|
|
- `python3`
|
|
- `pip3`
|
|
|
|
### 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 `pisa-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](https://www.python.org/downloads/) 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
|
|
|
|
`pisa-cli` has the following dependencies (which can be satisfied by using `pip install -r requirements.txt`):
|
|
|
|
- `cryptography`
|
|
- `requests` |
