How to set up a local development environment for Celo using Windows.
Many popular tools and resources for blockchain development are written for developers working on UNIX machines. It is common for developers working on Windows to encounter errors that are not covered in the documentation and have no luck with Google. Fortunately, Microsoft makes it easy to run a UNIX machine directly from a Windows desktop with the Windows Subsystem for Linux.
Getting set up with Windows
Open PowerShell as an administrator and run
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Restart your computer when prompted.
Next, install a Linux distribution from the Microsoft Store. When developing this guide, we chose Ubuntu.
Set up your Linux distro by setting a username and password then update and upgrade the packages by running the following command in the terminal:
sudo apt update && sudo apt upgrade
You can view the source documentation for setting up the Linux distro here and the Microsoft documentation for setting up the Windows Subsystem for Linux here.
Set up the Linux Environment
Now that you have Linux installed, let’s install nvm and yarn. Nvm (node version manager) makes it easy to install and manage different versions of Node.js. The following instructions are from the celo-monoreop setup documentation for Linux.
Run the following commands in the Linux terminal.
# Installing Nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
# Setting up the desired Nvm version
nvm install x
nvm alias default x
$ node -v in the terminal should print a node version if it is installed correctly.
Yarn is a package manager similar to npm. The celo-monorepo uses yarn to build and manage packages. Install yarn with the following command.
# Installing Yarn - https://yarnpkg.com/en/docs/install#debian-stable
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update && sudo apt-get install yarn
Test that yarn is installed by running
$ yarn --version.
Developing with WSL
You can now start working on your projects in your Linux environment. Install the WSL VS Code extension for a seamless integration between VS Code and WSL.
Be aware that networking will be different depending on which version of WSL you are using. The details of managing network interfaces goes beyond the scope of this guide, but you can learn more here.
