Installing Clojure locally

Installing the Clojure CLI

Clojure provides command line tools that can be used to start a Clojure repl, use Clojure and Java libraries, and start Clojure programs.

Linux

Ensure that the following dependencies are installed: bash, curl, rlwrap, and Java.

curl -O https://download.clojure.org/install/linux-install-1.10.3.967.sh
chmod +x linux-install-1.10.3.967.sh
sudo ./linux-install-1.10.3.967.sh

Homebrew for Mac OS X

Install the command line tools with brew from the clojure/tools tap:

brew install clojure/tools/clojure

Windows

For running Clojure on Windows it is recommended to use WSL2.

Another way to install Clojure on Windows is with the Scoop package manager. To install scoop, open PowerShell and run these 2 commands, one after the other:

iwr -useb get.scoop.sh | iex
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser -Force
``

To install Clojure with Scoop you have to add two important buckets first:

```sh
# if you don't have git version control system installed
# it is required for adding new external buckets to your scoop installer
# you can skip this step otherwise
scoop install git

# add scoop bucket for Java 
scoop bucket add java

# add scoop bucket for clojure build
scoop bucket add scoop-clojure https://github.com/littleli/scoop-clojure

Now we are ready to install Java and Clojure by issuing following commands:

# install Java runtime and compiler
scoop install adoptopenjdk-lts-hotspot

# install official clojure tools
scoop install clojure

# update to the newest version
scoop update clojure

After successfully running steps above, you should be able to run Clojure with the following:

clj
