-**TL;DR:** Use tools that encourage or enforce the same Node.js version across different environments and developers. Tools like [nvm](https://github.com/nvm-sh/nvm), and [Volta](https://volta.sh/) allow specifying the project's version in a file so each team member can run a single command to conform with the project's version.
