node安装和环境变量配置

约定不等于承诺〃 2023-02-16 10:57 25阅读 0赞

### 1、下载nodejs  ###

选择自己喜欢的 [nodejs][]，并下载，我用的是zip的，因为本地msi总是因为某个权限不够安装不了

--------------------

### 2、新建两个空的文件夹node\_cache 和 node\_global ###

--------------------

### 3、在路径输入cmd，打开命令行窗口，输入如下的命令 ###

>     npm config set prefix "C:\\software\\work\\node\\node\_global（你自己的，别用我的）"
> 
>     npm config set cache "C:\\software\\work\\node\\node\_cache（你自己的，别用我的）"

--------------------

### 4、配置环境变量 ###

新建NODE\_PATH,配置C:\\software\\work\\node\\node\_global\\node\_modules

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1Mjc1MjMz_size_16_color_FFFFFF_t_70 2][]

在path中配置，node.exe 和 node\_cache的路径

当然这些都需要是自己安装的路径，必须配置node的路径，要不然无法全局使用

--------------------

### 5、验证 ###

使用全局的cmd命令窗口，查看当前node和npm版本

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1Mjc1MjMz_size_16_color_FFFFFF_t_70 3][]

显示如图即为成功
