Methods of Installing Exercism CLI

• With Homebrew
• Without Homebrew

Homebrew is a package manager for OS X which installs the stuff that Apple didn't.

Find out if you have homebrew installed via the terminal.

You can open a terminal using Spotlight by pressing and then type 'terminal' in the space provided.

On the command prompt, type in the command:

\brew --version

If homebrew is installed you may see output like the following (version numbers may vary):

Homebrew 0.9.9 (git revision a5586; last commit 2016-05-09)
Homebrew/homebrew-core (git revision 3b4c; last commit 2016-05-09)

Install the CLI via homebrew in the following section. Otherwise see "Installing Without Homebrew".

Installing With Homebrew

Install the CLI via homebrew with the following command:

brew update && brew install exercism

Verify that it was installed properly by running:

exercism --version

If there was a problem you will get an error message saying command not found.

If everything is fine, you're done installing the CLI, and you can move on to the next step, which is configuring the CLI.

Installing Without Homebrew

This is described in detail in this video tutorial.

First you need to know which processor architecture your computer has. If you're not sure, you can use Terminal.app to find out:

Open Terminal.app and type in the following command:

uname -m

Common values are i386 (32-bit) and x86_64 (64-bit). If you have something different, you'll need to ask Google about the details.

If you don't have a directory in your home directory called bin, make one now:

mkdir ~/bin

Next, get the latest release from GitHub, making sure to get the one that is both for Mac and for your architecture:

Unzip the downloaded archive:

cd ~/Downloads
tar -xzvf exercism-mac-64bit.tgz

Move the exercism binary to the bin directory:

mv exercism ~/bin/

Check if ~/bin is on your path:

echo $PATH

Look for a section between two colons that looks like /Users/<your-username>/bin or ~/bin.

If it's not there, you need to add it. In order to do so, you'll need to know which shell you use, so that you can add it to the correct config.

Find out, by running:

echo $SHELL

If it says /bin/bash, then you're using the default that ships with the Mac. If not, you'll need to replace .bash_profile with the name of the correct config file.

echo 'export PATH=~/bin:$PATH' >> ~/.bash_profile

Finally, source your shell config:

source ~/.bash_profile

You should now have access to the exercism command:

exercism --version
