Installing Anaconda on Linux

Download Anaconda

From Anaconda site

  1. Download Anaconda installer for Linux from here: https://www.anaconda.com/download/
  2. Choose Python 2.7 or Python 3.6, read python2 vs python3

From Anaconda repository

  1. Download Anaconda installer for Linux from here: https://repo.continuum.io/archive/ using wget or from the browser.
  2. If you choose to use wget, check the latest version X.X.X, open up a terminal and replace the X.X.X with the latest version.
  3. For Python 2.7 : wget http://repo.continuum.io/archive/Anaconda2-X.X.X-Linux-x86_64.sh
  4. for Python 3.x: wget http://repo.continuum.io/archive/Anaconda3-5.0.1-Linux-x86_64.sh

Installing Anaconda

  1. Open up a terminal.
  2. cd to your installer folder.
  3. Type sh ./AnacondaXXXXXXXX.sh, where AnacondaXXXXXXXX.sh refers to the downloaded file name.
  4. Follow the instructions on the screen. Accept the defaults if you are not sure what to do :stuck_out_tongue:.
  5. Installation will be finished within 5 minutes.
  6. The following line will be appeared: Do you wish the installer to prepend the AnacondaX install location to PATH in your /home/XXX/.bashrc ? [yes|no]
  7. If you use bash, you can type yes for easy installation. Read the next session about PATH variable
  8. Everything is done. Refresh your bash terminal by source ~/.bashrc

Anaconda PATH variable

The Anaconda will NOT append the PATH variable during Linux installation. To qurantee your installation is successful, you need to check your rcfile for Bash, i.e. the .bashrc stored under the Home directory of Linux. To read the .bashrc:

  1. Type cat ~/.bashrc in your terminal.
  2. If you have the following lines at the end, it means the installation is OK. 
    # added by Anaconda2 installer
export PATH="/home/XXXXX/anacondaX/bin:$PATH"
  3. If you doesn’t got this line, first check the Anaconda installation location (usually /home/XXXXX/anacondaX/) and add the following line (Replace /home/XXXXX/anacondaX/ with your installation location) to ~/.bashrc using a text editor: 
    export PATH="/home/XXXXX/anacondaX/bin:$PATH"
  4. If you have no idea what is a text editor, open a terminal, type echo "export PATH="/home/XXXXX/anacondaX/bin:$PATH"" >> ~/.bashrc and enter, of course you need to replace your installation folder here.

Successful Anaconda installation

  1. Run source ~/.bashrc in the terminal.
  2. Type python in the terminal.
  3. Similar strings will be appeared: :heavy_check_mark: 
    Python 2.7.14 |Anaconda custom (64-bit)| (default, Oct 16 2017, 17:29:19) 
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
  4. If the following similar strings appeared, redo the previous session or run source ~/.bashrc in the terminal. :heavy_multiplication_x: 
    Python 2.7.14 (default, Jan  5 2018, 10:41:29)
