Have you created a package.json file? Maybe run this command first again.
你创建了一个package.json文件吗?也许再次运行此命令。
C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm init
It creates a package.json file in your folder.
它会在您的文件夹中创建一个package.json文件。
Then run,
C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm install socket.io --save
C:\ Users \ Nuwanst \ Documents \ NodeJS \ 3.chat> npm install socket.io --save
The "--save" ensures your module is saved as a dependency in your package.json file.
“--save”确保您的模块在package.json文件中保存为依赖项。

You need to make sure if package.json file exist in app folder. i run into same problem differently but solution would be same
您需要确保app.file文件中是否存在package.json文件。我遇到的问题不同,但解决方案是一样的
Run this command where "package.json" file exist. even i experience similar problem then i change the folder and got resolve it. for more explanation i run c:\selfPractice> npm start whereas my package.json resides in c:\selfPractice\frontend> then i change the folder and run c:\selfPractice\frontend> npm start and it got run
运行此命令,其中存在“package.json”文件。即使我遇到类似的问题,然后我更改文件夹并解决它。为了更多的解释我运行c:\ selfPractice> npm start而我的package.json位于c:\ selfPractice \ frontend>然后我更改文件夹并运行c:\ selfPractice \ frontend> npm start并运行
