You will need to have Rust installed. You can get it by visiting <https://rustup.rs>. This'll also install Cargo, Rust's package/project manager. You will need to have Rust installed. You can get it by visiting <https://rustup.rs>. This'll also install Cargo, Rust's package/project manager.
## MacOS/Linux <!-- TODO: Installation with Cargo -->
Just run:
```bash
curl -L https://raw.githubusercontent.com/rust-lang/rustlings/main/install.sh | bash
```
Or if you want it to be installed to a different path:
```bash
curl -L https://raw.githubusercontent.com/rust-lang/rustlings/main/install.sh | bash -s mypath/
```
This will install Rustlings and give you access to the `rustlings` command. Run it to get started!
### Nix
Basically: Clone the repository at the latest tag, finally run `nix develop` or `nix-shell`.
```bash
# find out the latest version at https://github.com/rust-lang/rustlings/releases/latest (on edit 5.6.1)
git clone -b 5.6.1 --depth 1 https://github.com/rust-lang/rustlings
cd rustlings
# if nix version > 2.3
nix develop
# if nix version <= 2.3
nix-shell
```
## Windows
In PowerShell (Run as Administrator), set `ExecutionPolicy` to `RemoteSigned`:
```ps1
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
```
Then, you can run:
```ps1
Start-BitsTransfer -Source https://raw.githubusercontent.com/rust-lang/rustlings/main/install.ps1 -Destination $env:TMP/install_rustlings.ps1; Unblock-File $env:TMP/install_rustlings.ps1; Invoke-Expression $env:TMP/install_rustlings.ps1
```
To install Rustlings. Same as on MacOS/Linux, you will have access to the `rustlings` command after it. Keep in mind that this works best in PowerShell, and any other terminals may give you errors.
If you get a permission denied message, you might have to exclude the directory where you cloned Rustlings in your antivirus.
## Browser
[![Open in Gitpod](https://gitpod.io/button/open-in-gitpod.svg)](https://gitpod.io/#https://github.com/rust-lang/rustlings)
[![Open Rustlings On Codespaces](https://github.com/codespaces/badge.svg)](https://github.com/codespaces/new/?repo=rust-lang%2Frustlings&ref=main)
## Manually
Basically: Clone the repository at the latest tag, run `cargo install --path .`.
```bash
# find out the latest version at https://github.com/rust-lang/rustlings/releases/latest (on edit 5.6.1)
git clone -b 5.6.1 --depth 1 https://github.com/rust-lang/rustlings
cd rustlings
cargo install --force --path .
```
If there are installation errors, ensure that your toolchain is up to date. For the latest, run:
```bash
rustup update
```
Then, same as above, run `rustlings` to get started.
