### Build from source ### Build from Source
Clone on Linux or Mac: Follow the [build instruction for contributors](#development).
```bash
git clone --recurse-submodules https://github.com/denoland/deno.git
```
On Windows, a couple extra steps are required to clone because we use symlinks
in the repository. First
[enable "Developer Mode"](https://www.google.com/search?q=windows+enable+developer+mode)
(otherwise symlinks would require administrator privileges). Then you must set
`core.symlinks=true` before the checkout is started.
```bash
git config --global core.symlinks true
git clone --recurse-submodules https://github.com/denoland/deno.git
```
Now we can start the build:
```bash
# Build.
cargo build -vv
# Run.
./target/debug/deno tests/002_hello.ts
# Test.
cargo test
# Format code.
./tools/format.py
```
#### Prerequisites
To ensure reproducible builds, Deno has most of its dependencies in a git
submodule. However, you need to install separately:
1. [Rust](https://www.rust-lang.org/en-US/install.html) >= 1.36.0
2. Python 2.
[Not 3](https://github.com/denoland/deno/issues/464#issuecomment-411795578).
Extra steps for Mac users: install [XCode](https://developer.apple.com/xcode/)
:(
Extra steps for Windows users:
<!-- prettier-ignore-start -->
<!-- see https://github.com/prettier/prettier/issues/3679 -->
1. Add `python.exe` to `PATH` (e.g. `set PATH=%PATH%;C:\Python27\python.exe`)
2. Get [VS Community 2017](https://www.visualstudio.com/downloads/) with
"Desktop development with C++" toolkit and make sure to select the following
required tools listed below along with all C++ tools.
- Windows 10 SDK >= 10.0.17134
- Visual C++ ATL for x86 and x64
- Visual C++ MFC for x86 and x64
- C++ profiling tools
3. Enable "Debugging Tools for Windows". Go to "Control Panel" → "Programs" →
"Programs and Features" → Select "Windows Software Development Kit - Windows
10" → "Change" → "Change" → Check "Debugging Tools For Windows" → "Change" ->
"Finish".
4. Make sure you are using git version 2.19.2.windows.1 or newer.

<!-- see https://github.com/prettier/prettier/issues/3679 -->
1. [Rust](https://www.rust-lang.org/en-US/install.html)

https://github.com/denoland/deno/blob/master/.github/workflows/ci.yml).
This is updated frequently.
2. [Python 2](https://www.python.org/downloads)
- Ensure that a suffix-less `python`/`python.exe` exists in your `PATH` and
it refers to Python 2, [not 3](
