Software Requirement

If you encounter a problem, please look for a online solution. The installation and configuration described below is mostly performed using a bash shell on macOS. Windows users will need to install and configure a bash shell in order to follow the usage shown below. Try to use Windows Subsystem for Linux for this purpose.

macOS/Linux

Installing software for macOS/Linux

If you are new to using Bash refer to the following lessons with Software Carpentry: http://swcarpentry.github.io/shell-novice/

Homebrew and other package

  • If you don't have Homebrew, you can install it by pasting below code in your macOS/Linux terminal.

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

  • Install wget (for downloading data). Use Hombrew to install it by pasting below code in your macOS terminal.

    brew install wget

Windows

Enable the Windows Subsytem for Linux

If you are using Windows machine, it's recomended to follow below step. You will experience an error during SPEI calculation cause by NCO if you use standard Windows 10 and not using Windows Subsytem for Linux.

Guideline below are specific for Windows 10. If you are using Windows Server 2019, please follow Windows Server Installation Guide

Reference: https://docs.microsoft.com/en-us/windows/wsl/install-win10

You must first enable the "Windows Subsystem for Linux - WSL" optional feature before installing any Linux distributions on Windows.

Installing software for Windows

If you have a Bash shell already installed on your Windows OS (e.g. Ubuntu Bash) you can use that for the exercise, but it must be a Bash shell

If you are new to using Bash refer to the following lessons with Software Carpentry: http://swcarpentry.github.io/shell-novice/

Homebrew and other package

  • If you don't have Homebrew, you can install it by pasting below code in your WSL Ubuntu terminal.

    bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

  • Install wget (for downloading data). Use Hombrew to install it by pasting below code in your WSL Ubuntu terminal.

    brew install wget

Anaconda

  • Download and install Anaconda Python on your WSL Ubuntu Linux: Ubuntu Linux on WSL.

    climate-indices python package used for SPEI calculation is rely on netCDF Operator (NCO) and pyNCO wrapper sometimes produce an error in Windows. That's the reason why we will use Anaconda for Linux if you are using Windows machine.

  • Go to https://repo.anaconda.com/archive/ to find the list of Anaconda releases

  • Select the release you want. I have a 64-bit computer, so I chose the latest release ending in x86_64.sh. If I had a 32-bit computer, I'd select the x86.sh version. If you accidentally try to install the wrong one, you'll get a warning in the terminal. I chose Anaconda3-2020.11-Linux-x86_64.sh.

  • From the terminal run wget https://repo.anaconda.com/archive/[YOUR VERSION]. Example: 

    wget https://repo.anaconda.com/archive/Anaconda3-2020.11-Linux-x86_64.sh

  • After download process completed, Run the installation script: bash Anaconda[YOUR VERSION].sh 

    bash Anaconda3-2020.11-Linux-x86_64.sh

  • Read the license agreement and follow the prompts to press Return/Enter to accept. Later will follow with question on accept the license terms, type yes and Enter. When asks you if you'd like the installer to prepend it to the path, press Return/Enter to confirm the location. Last question will be about initialize Anaconda3, type yes then Enter.

  • Close the terminal and reopen it to reload .bash configs. It will automatically activate base environment.

  • Deactivate base environment then set to false the confirguration of auto activate the base environment by typing

    conda deactivate && conda config --set auto_activate_base false

  • To test that it worked, which python in your Terminal. It should print a path that has anaconda in it. Mine is /home/gost/anaconda3/bin/python. If it doesn't have anaconda in the path, do the next step.

  • Manually add the Anaconda bin folder to your PATH. To do this, I added "export PATH=/home/gost/anaconda3/bin:$PATH" to the bottom of my ~/.bashrc file.

  • Optionally install Visual Studio Code when prompted
