Nvm is called node.js version management in English and is a version management tool for nodejs. Nvm and n are both node.js version management tools. In order to solve the incompatibility of various versions of node.js, you can install and switch different versions of node.js through it.

Nvm 1.1.7-noinstall.zip: green installation-free version, but need to be configured when using it (http://nvm.uihtm.com/nvm1.1.7-noinstall.zip)

Nvm Command prompt

Nvm arch: shows whether node is running on 32-bit or 64-bit.

Nvm install [arch]: install node. Version is either a specific version or the latest stable version of latest. The optional parameter arch specifies whether to install the 32-bit or 64-bit version, and the default is the number of system bits. You can add-- insecure to bypass the SSL of the remote server.

Nvm list [available]: displays a list of installed ones. The optional parameter available displays all installable versions. List can be simplified to ls.

Nvm on: enable node.js version management.

Nvm off: turn off node.js version management.

Nvm proxy [url]: sets the download agent. Displays the current proxy without the optional parameter url. Setting url to none removes the proxy.

Nvm node_mirror [url]: sets the node image. The default is https://nodejs.org/dist/. If you do not write url, the default url is used. After setting up, you can check the settings.txt file in the installation directory, or you can operate directly in that file.

Nvm install latest installs the latest version (you can see the corresponding version numbers of node.js and npm above during installation. It is not recommended to install the latest version)

Nvm install version number installs the specified version of nodejs

View installed version

Nvm list or nvm ls check the currently installed version (there is no * in front of the current version number, and no version is used at this time, so an error will be reported when using node.js)
