# Getting started
|
||
|
||
GHCup makes it easy to install specific versions of GHC on GNU/Linux,
|
||
macOS (aka Darwin), FreeBSD and Windows and can also bootstrap a fresh [Haskell developer environment](./install/#supported-tools) from scratch.
|
||
It follows the unix UNIX philosophy of [do one thing and do it well](https://en.wikipedia.org/wiki/Unix_philosophy#Do_One_Thing_and_Do_It_Well). Similar in scope to [rustup](https://github.com/rust-lang-nursery/rustup.rs), [pyenv](https://github.com/pyenv/pyenv) and [jenv](http://www.jenv.be).
|
||
|
||
## Installation
|
||
|
||
The following commands will download the `ghcup` binary into `~/.ghcup/bin` (or `C:\ghcup\bin` on windows) and then
|
||
run it to interactively install the [Haskell Toolchain](#supported-tools). These commands should be run as **non-root/non-admin
|
||
user**.
|
||
|
||
For Linux, macOS, FreeBSD or Windows Subsystem 2 for Linux, run this in a terminal:
|
||
|
||
```sh
|
||
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
|
||
```
|
||
|
||
For Windows, run this in a PowerShell session:
|
||
|
||
```psh
|
||
Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $true
|
||
```
|
||
|
||
If you want to know what these scripts do, check out the [source code at the repository](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/scripts/bootstrap). Advanced users may want to perform a [manual installation](#manual-install) and GPG verify the binaries.
|
||
|
||
### Which versions get installed?
|
||
|
||
GHCup has two main channels for every tool: **recommended** and **latest**. By default, it installs *recommended*.
|
||
|
||
*latest* follows the latest release of every tool, while *recommended* is at the discretion of the GHCup maintainers and based on community adoption (hackage libraries, tools like HLS, stackage support, etc.) and known bugs.
|
||
|
||
Also see [tags and shortcuts](../guide/#tags-and-shortcuts) for more information.
|
||
|
||
## First steps
|
||
|
||
1. To get started with creating a Haskell project, follow the [Getting Started with Haskell and Cabal](https://cabal.readthedocs.io/en/latest/getting-started.html) guide
|
||
2. To properly learn Haskell, run through the [CIS 194 Haskell course](https://www.cis.upenn.edu/~cis194/spring13/) including exercises
|
||
3. To learn more about Haskell Toolchain management, check out the [ghcup user guide](./guide.md)
|
||
|
||
## Uninstallation
|
||
|
||
On linux, just run `ghcup nuke`, then make sure any ghcup added lines in your `~/.bashrc` (or similar) are removed.
|
||
|
||
On windows, double-click on the `Uninstall Haskell.ps1` PowerShell script on your Desktop.
|
||
|
||
## Supported tools
|
||
|
||
GHCup supports the following tools, which are also known as the **Haskell Toolchain**:
|
||
|
||
1. [GHC](https://www.haskell.org/ghc/)
|
||
2. [cabal-install](https://cabal.readthedocs.io/en/latest/)
|
||
3. [haskell-language-server](https://haskell-language-server.readthedocs.io/en/latest/)
|
||
4. [stack](https://docs.haskellstack.org/en/latest/README/)
|
||
|
||
## Supported platforms
|
||
|
||
This list may not be exhaustive and specifies support for bindists only.

### Windows 7
|
||
|
||
May or may not work, several issues:
|
||
|
||
* [https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140)
|
||
* [https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197](https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197)
|
||
|
||
### WSL1
|
||
|
||
Unsupported. GHC may or may not work. Upgrade to WSL2.
|
||
|
||
### MacOS <13
|
||
|
||
Not supported. Would require separate binaries, since >=13 binaries are incompatible.
|
||
Please upgrade.
|
||
|
||
### MacOS aarch64
|
||
|
||
HLS bindists are still experimental. Stack is theoretically supported, but has no binaries yet.
|
||
|
||
### FreeBSD
|
||
|
||
Lacks some upstream bindists and may need compat libs, since most bindists are built on FreeBSD-12.
|
||
HLS bindists are experimental.
|
||
|
||
### Linux ARMv7/AARCH64
|
||
|
||
Lower availability of bindists. HLS only has experimental ones. Stack not supported currently.
|
||
|
||
## Manual install
|
||
|
||
Download the binary for your platform at [https://downloads.haskell.org/~ghcup/](https://downloads.haskell.org/~ghcup/)
|
||
and place it into your `PATH` anywhere.
|
||
|
||
If you want to GPG verify the binaries, import the following key first: `7784930957807690A66EBDBE3786C5262ECB4A3F`.
|
||
|
||
Then adjust your `PATH` in `~/.bashrc` (or similar, depending on your shell) like so:
|
||
|
||
```sh
|
||
export PATH="$HOME/.cabal/bin:$HOME/.ghcup/bin:$PATH"
|
||
```
|
||
|
||
## Vim integration
