新安装的node使用 npm无法install问题

当我们新安装好node之后，可能会遇到npm install 下载依赖包的时候，显示下面这种报错：

npm WARN registry Unexpected warning for http://registry.npmjs.org/:ot permitted, open 'D:\\\\Software\\\\node\\\\node_cache\\\\_cacache\\\\tmp\\\\d

那么这个问题是为什么呢？
npmrc 这个文件是我们没有配置好，导致的不能使用，我们应该再安装完node之后，使用cmd管理员身份打开，然后配置一下变量

npm config set cache "D:\\Software\\node\\node_cache"
npm config set prefix "D:\\Software\\node\\node_global"
npm install -g cnpm --registry=https://registry.npm.taobao.org

然后看一下node环境配置

解决办法：
在 c盘目录下找到那个默认隐藏的文件如C:\\Users{账户}\\下的.npmrc文件 把它删除掉 记住 不是node.js安装目录下的那个！
