## 1、下载安装包 ##

Node.js 官方网站下载：[https://nodejs.org/en/][https_nodejs.org_en]

## 2、安装 ##

打开安装，傻瓜式下一步即可：

选择安装位置，我这里装在D盘下：

安装成功，按Ctrl+R键输入cmd：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5nbGlhbmc2NjY_size_16_color_FFFFFF_t_70 8][]

此时可以执行 node -v 和 npm -v 分别查看node和npm的版本号：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5nbGlhbmc2NjY_size_16_color_FFFFFF_t_70 9][]

### 三、环境配置 ###

说明：这里的环境配置主要配置的是npm安装的全局模块所在的路径，以及缓存cache的路径，之所以要配置，是因为以后在执行类似：npm install express \[-g\] （后面的可选参数-g，g代表global全局安装的意思）的安装语句时，会将安装的模块安装到【C:\\Users\\用户名\\AppData\\Roaming\\npm】路径中，占C盘空间。  
例如：我希望将全模块所在路径和缓存路径放在我node.js安装的文件夹中，则在我安装的文件夹【D:\\Program Files\\nodejs】下创建两个文件夹【node\_global】及【node\_cache】

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5nbGlhbmc2NjY_size_16_color_FFFFFF_t_70 10][]

创建完两个空文件夹之后，打开cmd命令窗口，输入

npm config set prefix "D:\Program Files\nodejs\node_global"
    npm config set cache "D:\Program Files\nodejs\node_cache"

接下来设置环境变量，关闭cmd窗口，“我的电脑”-右键-“属性”-“高级系统设置”-“高级”-“环境变量”

进入环境变量对话框，在【系统变量】下新建【NODE\_PATH】，输入【D:\\Program Files\\nodejs\\node\_modules】，将【用户变量】下的【Path】修改为【D:\\Program Files\\nodejs\\node\_global】

### 四、测试 ###

配置完后，安装个module测试下
