如何使用

Usage:

  nvm current                  : Display active version.
  nvm debug                    : Check the NVM4W process for known problems (troubleshooter).
  nvm install <version> [arch] : The version can be a specific version, "latest" for the latest current version, or "lts" for the
                                 most recent LTS version. Optionally specify whether to install the 32 or 64 bit version (defaults
                                 to system arch). Set [arch] to "all" to install 32 AND 64 bit versions.
                                 Add --insecure to the end of this command to bypass SSL validation of the remote download server.
  nvm list [available]         : List the node.js installations. Type "available" at the end to see what can be installed. Aliased as ls.

  nvm off                      : Disable node.js version management.
  nvm proxy [url]              : Set a proxy to use for downloads. Leave [url] blank to see the current proxy.
                                 Set [url] to "none" to remove the proxy.
  nvm node_mirror [url]        : Set the node mirror. Defaults to https://nodejs.org/dist/. Leave [url] blank to use default url.
  nvm npm_mirror [url]         : Set the npm mirror. Defaults to https://github.com/npm/cli/archive/. Leave [url] blank to default url.

  nvm upgrade                  : Update nvm to the latest version. Manual rollback available for 7 days after upgrade.
  nvm use [version] [arch]     : Switch to use the specified version. Optionally use "latest", "lts", or "newest".
                                 "newest" is the latest installed version. Optionally specify 32/64bit architecture.
                                 nvm use <arch> will continue using the selected version, but switch to 32/64 bit mode.
  nvm reinstall <version>      : A shortcut method to clean and reinstall a specific version.

                                 If <path> is not set, the current root will be displayed.
