NVM allows you to install different versions of Node, and switch between these versions depending on the project that you're working on via the command line. Instead of using npm to install and uninstall Node versions for your different projects, you can use nvm, which helps you effectively manage your node versions for each project. In fact, you would most likely get a warning that says: This project requires Node version X And if you update the Node version to 12.0.0 with npm, and you use it for a project that uses 10.0.0, you may not get the expected experience. Using only one version (the one installed by npm) for these different projects may not give you accurate execution results.įor example, if you use a Node version of 10.0.0 for a project that uses 12.0.0, you may get some errors.
