node.js中npm的安装问题

node.js中npm安装的模块在哪个目录下

初学node.js，node安装在F盘，然后

npm install xss
xss@0.0.6 node_modules\xss

但是在f:\node\node_modules目录没有看到xss模块，请问安装的源码在哪呢？
ps:有点js基础，如何快速掌握node，新人致谢

npm安装模块默认为 shell 的当前目录。如果要装成全局的，使用 npm install xss -g

npm help install里的描述是：

Packages are dropped into the node_modules folder under the prefix. Global installs on Unix systems go to {prefix}/lib/node_modules. Global installs on Windows go to {prefix}/node_modules (that is,no lib folder.)

翻译出来大意是：

Packages 安装进 prefix 前缀的 node_modules。Unix系统里 Global 安装会装进{prefix}/lib/node_modules。Windows系统里则是 {prefix}/node_modules （就是说没有 lib 文件夹）。

通过 npm config ls 可列出 prefix 的配置

修改 prefix 可以 npm config set prefix "f:\node"

以上知识我都是 npm help + Google 得出来的，其实我学 node 也没多久。好的学习方法可以自己快速得到答案。

错误代码如上：

解决办法：

删除npmrc文件。

 

使用镜像

 

 

镜像使用方法（三种办法任意一种都能解决问题，建议使用第三种，将配置写死，下次用的时候配置还在）:

1.通过config命令

1

2

npm config set registry http://registry.cnpmjs.org

npm info underscore （如果上面配置正确这个命令会有字符串response）

2.命令行指定

1

npm --registry http://registry.cnpmjs.org info underscore

3.编辑 ~/.npmrc 加入下面内容

1

registry = http://registry.cnpmjs.org

 

结果：

E:\study\angular-phonecat>npm config set registry http://registry.cnpmjs.org

E:\study\angular-phonecat>npm install
