最近想使用nvm管理node环境，安装后发现使用nvm切换node版本无效，一不小心又把windows的node环境搞挂了，于是卸载，还原。今天有时间，于是再次尝试安装nvm来管理node，并记录下来分享和备用。
一、nvm的安装

下载nvm
去https://github.com/coreybutler/nvm-windows/releases下载nvm-windows

二、nvm的使用
- 查看nvm版本
nvm version
1.1.7
- 使用nvm安装node
以12.3.0版本为例
nvm install 12.3.0
- 查看安装的node
nvm list 或 nvm ls
12.3.0
* 10.15.3 (Currently using 64-bit executable)
- 使用nvm切换node版本
以12.3.0为例
# 切换到12.3.0
nvm use 12.3.0
Now using node v12.3.0 (64-bit)
# 查看node版本
node -v
v12.3.0
- nvm的更多用法
Usage:
nvm arch : Show if node is running in 32 or 64 bit mode.
nvm install <version> [arch] : The version can be a node.js version or "latest" for the latest stable 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 on : Enable node.js version management.
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 uninstall <version> : The version must be a specific version.
nvm use [version] [arch] : Switch to use the specified version. Optionally specify 32/64bit architecture.
nvm use <arch> will continue using the selected version, but switch to 32/64 bit mode.
nvm root [path] : Set the directory where nvm should store different versions of node.js.
If <path> is not set, the current root will be displayed.
nvm version : Displays the current running version of nvm for Windows. Aliased as v.
