preface

Reasons for using NVM:

Because multiple projects use different versions of Node and NPM environments:

  • Iview source gulp relies on Node V10
  • Taro depends on the environment in Node V12 and above

Therefore, NVM is introduced to solve node environment problems

The function of NVM

Node.js Version Management NVM is a node.js version management tool. It allows you to install and switch between different versions of NodeJS

The use of NVM

The installation

Git:github.com/coreybutler…

  • Nvm-noinstall. zip: green installation-free version, which requires configuration.
  • Nvm-setup. zip: installation version, recommended

As a foolproof next step, you can choose your own NVM installation path and Node installation path. Note that the installation path should not appear Chinese and space

  • After installation

Enter NVM to verify that the installation was successful
