Clone on Linux or Mac:

    Extra steps for Windows users:

    1. (otherwise symlinks would require administrator privileges).
    2. Make sure you are using git version 2.19.2.windows.1 or newer.

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

    1. cargo build -vv

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

    When building V8 from source, there are more dependencies:

    Python 2. Ensure that a suffix-less /python.exe exists in your PATH and it refers to Python 2, .

    Mac users must have Command Line Tools installed. (XCode already includes CLT. Run to install it without XCode.)

    For Windows users:

    1. Get 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++ 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 for more details about the V8 build.

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