Can Yarn and NVM Coexist on Windows?
It's a while ago you asked, but I just stepped over your question.
You can simply install yarn as node module globally:
npm i -g yarnThis works very nicely when using nvm-windows.
Additional hint: Since switching to a new node version with nvm requires to re-install all globally installed node modules, I started to use yarn instead of npm for managing all other global modules except of npm and yarn itself. This way, updating node is quite painless.
