Building from source

Below are instructions on how to build Deno from source. If you just want to use Deno you can download a prebuilt executable (more information in the Getting Started chapter).

Cloning the Repository

Clone on Linux or Mac:

git clone --recurse-submodules https://github.com/denoland/deno.git

Extra steps for Windows users:

  1. Enable "Developer Mode" (otherwise symlinks would require administrator privileges).
  2. Make sure you are using git version 2.19.2.windows.1 or newer.
  3. Set core.symlinks=true before the checkout: 
    git config --global core.symlinks true
git clone --recurse-submodules https://github.com/denoland/deno.git

Prerequisites

The easiest way to build Deno is by using a precompiled version of V8:

cargo build -vv

However if you want to build Deno and V8 from source code:

V8_FROM_SOURCE=1 cargo build -vv

When building V8 from source, there are more dependencies:

Python 2. Ensure that a suffix-less python/python.exe exists in your PATH and it refers to Python 2, not 3.

For Linux users glib-2.0 development files must also be installed. (On Ubuntu, run apt install libglib2.0-dev.)

Mac users must have XCode installed.

For Windows users:

  1. Get VS Community 2019 with "Desktop development with C++" toolkit and make sure to select the following required tools listed below along with all C++ tools.

    • Visual C++ tools for CMake
    • Windows 10 SDK (10.0.17763.0)
    • Testing tools core features - Build Tools
    • Visual C++ ATL for x86 and x64
    • Visual C++ MFC for x86 and x64
    • C++/CLI support
    • VC++ 2015.3 v14.00 (v140) toolset for desktop

  2. 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". Or use: Debugging Tools for Windows (Notice: it will download the files, you should install X64 Debuggers And Tools-x64_en-us.msi file manually.)

See rusty_v8's README for more details about the V8 build.

Building

Build with Cargo:

# Build:
cargo build -vv

# Build errors?  Ensure you have latest master and try building again, or if that doesn't work try:
cargo clean && cargo build -vv

# Run:
./target/debug/deno run cli/tests/002_hello.ts
