Download the compiler

You can download the latest version of the Nim compiler here.



Since the website moved to https, only installation via the provided zipfiles is supported:

  • 32 bit:
    SHA-256 69af94a6875a02543c1bf0fa03c665f126f8500a2c0e226c32571e64c6842e57

  • 64 bit:
    SHA-256 e667cdad1ae8e9429147aea5031fa8a80c4ccef6d274cec0e9480252d9c3168c

Unzip these where you want and optionally run finish.exe to detect your MingW environment. (Though that's not reliable yet.)

You can find the required DLLs here, if you lack them for some reason:

  • 32 and 64 bit:
    SHA-256 198112d3d6dc74d7964ba452158d44bfa57adef4dc47be8c39903f2a24e4a555

These versions of mingw are known to work:

  • 32 bit: mingw32-6.3.0
    SHA-256 1239a56d4c42e146b2cb25dc4d0871bd83f569d0a51a9198e84d010e0a75745a

  • 64 bit: mingw64-6.3.0
    SHA-256 9a23d12d96a10e67093c1f2042275c6a7d29da9e2ead573d0f24f4a6d53761a1

Installation based on generated C code

Note: The Nim compiler requires a C compiler to compile software. On Windows we recommend that you use Mingw-w64. GCC is recommended on Linux and Clang on Mac. The Windows installers above already includes a C compiler.

This installation method is the preferred way for Linux, Mac OS X, and other Unix like systems.

Firstly, download this archive:

Extract the archive. Then copy the extracted files into your chosen installation directory, ideally somewhere in your home directory. For example: ~/programs/nim.

Now open a terminal and follow these instructions:

  • cd into your installation directory, for example by executing

cd ~/programs/nim.

  • run sh
  • Add $your_install_dir/bin to your PATH.
  • To build associated tools like nimble and nimsuggest run nim c koch && ./koch tools.

After restarting your terminal, you should be able to run nim -v which should show you the version of Nim you just installed.

There are other ways to install Nim (like using the script), but these tend to cause more problems.

Bleeding edge installation from GitHub

GitHub is where Nim's development takes place. You may wish to grab the latest development version of Nim, because sometimes bug fixes and new features may not have made it to an official release yet. In those circumstances you are better off grabbing the current development branch.

You will also need to do this if you would like to contribute to Nim.

Before you download the code, open a new terminal and cd into the directory where you would like the download to take place.

The following commands can be used to download the current development branch and then to build it:

git clone
cd Nim
git clone --depth 1
cd csources && sh
cd ..
bin/nim c koch
./koch boot -d:release

You should then add the ./bin (make sure to expand this into an absolute path) directory to your PATH.

Docker Hub

The official Docker images are published on Docker Hub and include the compiler and Nimble. There are images for standalone scripts as well as Nimble packages.

Get the latest stable image:

docker pull nimlang/nim

The latest development version:

docker pull nimlang/nim:devel
