当我跑
时npm -v gulp-rev
输出是：
3.10.9
但是当我这样做时：
npm install gulp-rev@3.10.9
输出是：

这里发生了什么？

npm -v没有额外的论据。它只会返回您拥有的npm版本。在您的情况下，npm版本为3.10.9。
npm install <pkg>@<ver>尝试安装软件包的版本。因此，npm install gulp-rev@3.10.9会尝试安装包gulp-rev v3.10.9。
您看到的错误表明程序包管理器npm找不到程序包3.10.9的版本gulp-rev。
您应该查看npm view <pkg> or npm info <pkg>的输出。如下所示，找出包的可用版本：
$ npm info gulp-rev

如果您想查找已安装软件包的版本，请输入：
npm list

npm -v gulp-rev是一个有点无效的命令。它没有为您提供npm-package gulp-rev的最新版本号，但是您当前安装的npm版本号为3.10.9。
你试图安装一个不存在的gulp-rev版本。
要安装最新版本的gulp-rev，您只需输入npm install gulp-rev
