npm强制时不从缓存中安装tar包

Question

我使用的是Node v5.0.0和npm v3.3.6,并且在tar包中遇到了一个非常孤立的问题.由于企业防火墙,我被迫克隆Git存储库并从中安装它

我的问题是尽管迫使npm从缓存中安装软件包,tar但是唯一一个坚持从npm的注册表下载它的软件包.

$ npm install tar@2.2.1 --verbose --cache-min=999999999999                                     
npm info it worked if it ends with ok

我已经仔细检查了我的缓存,并且可以看到tar v2.2.1实际上存在且功能正常.

$ npm cache list | grep 'tar\\2.2.1'
~\AppData\Roaming\npm-cache\tar\2.2.1
~\AppData\Roaming\npm-cache\tar\2.2.1\package
~\AppData\Roaming\npm-cache\tar\2.2.1\package.tgz
~\AppData\Roaming\npm-cache\tar\2.2.1\package\package.json

对于它的价值,我能够通过简单地在我的依赖文件夹添加项目的Git仓库来克服这个问题,使用npm install deps/node-tar前做npm install.但是,仍然没有解释手头的问题.
