通过npm安装节点模块时出错

我想通过npm在本地安装节点模块redis v0.9.0。我从https://registry.npmjs.org/redis/-/redis-0.9.0.tgz下载了tgz文件。现在，当我尝试执行命令npm install redis-0.9.0.tgz时，它试图从存储库中再次下载，而不是仅仅解压缩和安装。我正在尝试在Linux环境下的命令。我不明白为什么它会尝试下载。通过npm安装节点模块时出错

尝试安装它以这样的方式

npm install ./redis-0.9.0.tgz

的区别是什么，它使得当我们用'/'？ – user850234

只要确保您从当前目录中读取 –

我无法理解的一点是，以前我能够使用命令“npm install redis-0.9.0.tgz”进行安装，但并未尝试下载。但是现在为什么同一个命令不是突然工作，而是试图下载。任何想法可能是什么原因呢？ – user850234
