  2. Click the EXE file and pay attention to modifying the installation root directory of NVM and the installation root directory of node, which is the storage address of source files for managing multiple versions of node in the future
  3. Open system CMD and enter the directory in turn

    • nvm -versionCheck whether the NVM is installed successfully
    • NVM install (node version number you need to install)You can check it on the official websiteList of previous versions
    • be careful!!! In the previous step, the corresponding version of NPM will be installed directly at the same time
    • NVM use (node version number you need to install)Generally, the system permission use box will pop up, which can be passed in some key points
