You're trying to install it without a package.jsonfile, and in your solution you installed it globally, which is usually not what you want for socket.io.
您尝试在没有package.json文件的情况下安装它，并且在您的解决方案中全局安装它，这通常不是您想要的 socket.io。
Instead, you should include a package.jsonfile in your working directory and either run:
相反，您应该在工作目录中包含一个package.json文件，然后运行：
> npm install socket.io --save
which will automatically append it to package.json, or your you can physically include it in the dependencies and then just run:
这将自动将其附加到package.json，或者您可以将其物理包含在依赖项中，然后运行：
> npm install
