# nvm是什么 #

nvm全名node.js version management，顾名思义是一个nodejs的版本管理工具。通过它可以安装和切换不同版本的nodejs。

# 下载 #

[https://github.com/coreybutler/nvm-windows/releases][https_github.com_coreybutler_nvm-windows_releases]  
推荐使用`nvm-setup.zip`

解压安装，安装完成后 `cmd`窗口运行`nvm`命令，验证是否安装成功。

# 安装/管理nodejs #

1。 查看本地安装的所有版本；有可选参数available，显示所有可下载的版本。

nvm list [available]
    nvm ls

1.  安装，命令中的版本号可自定义，具体参考命令1查询出来的列表

nvm install 10.15.0

1.  使用特定版本

nvm use 10.15.0

1.  卸载

nvm uninstall 10.15.0

# 设置淘宝镜像源 #

1.  打开nvm的安装路径
2.  打开settings.txt，加入下面内容

arch: 64 
    proxy: none
    node_mirror: http://npm.taobao.org/mirrors/node/
    npm_mirror: https://npm.taobao.org/mirrors/npm/

# `npm install`报错原因 #

## 输入`npm install` 报错npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! node-sass@4.13.1 postinstall: `node scripts/build.js` ##

sass安装时获取源的问题，修改sass安装的源，使用taobao的npm

npm config set sass_binary_site=https://npm.taobao.org/mirrors/node-sass

然后运行`npm install`

## Module build failed: Error: ENOENT: no such file or directory ##

npm rebuild node-sass

## 【Vue】“npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed.” ##

解决：手动安装ajv即可。

npm install ajv@^6.0.0
