Sorry to say this, but currently, Takomo doesn't work on Windows, so you need to have Linux or Mac. Takomo is built with Node.js and requires Node.js v14.4.0 or later.
The recommended way to install Takomo is to add it as a development dependency in your project's package.json.
Initialize a new project if needed:
npm init -y
Add Takomo as a development dependency:
npm install -D takomo
npx tkm --version
You can, of course, use global installation, too.
npm install -g takomo
