If you already have package-lock.jsonfile just delete it and try again.

如果您已经有package-lock.json文件，只需将其删除并重试。

Have you created a package.jsonfile? Maybe run this command first again.

您是否创建了package.json文件？也许再次运行此命令。

C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm init

C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm init

It creates a package.jsonfile in your folder.

它会在您的文件夹中创建一个package.json文件。

Then run,

然后跑，

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 --saveensures your module is saved as a dependency in your package.jsonfile.

在--save确保您的模块保存为您的依赖关系的package.json文件。

Let me know if this works.

让我知道这个是否奏效。

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 文件夹中是否存在 package.json 文件。我以不同的方式遇到相同的问题，但解决方案是相同的

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

在“package.json”文件存在的地方运行这个命令。即使我遇到了类似的问题，然后我更改了文件夹并解决了它。有关更多解释，我运行 c:\selfPractice> npm start 而我的 package.json 驻留在 c:\selfPractice\frontend> 然后我更改文件夹并运行 c:\selfPractice\frontend> npm start 并运行

I had this in a new project on Windows. npm installhad created a node_modulesfolder for me, but it had somehow created the folder without giving me full control over it. I gave myself full control over node_modulesand node_modules\.stagingand it worked after that.

我在 Windows 上的一个新项目中有这个。为我npm install创建了一个node_modules文件夹，但它以某种方式创建了该文件夹，而没有让我完全控制它。我让自己完全控制node_modules，node_modules\.staging然后它就起作用了。

if your node_modules got installed in say /home/UserName/ like in my case, your package-lock.json file will also be there. just delete this file, go back to your app folder and run npm initand then npm install <pkgname>(e.g express) and a new node_modules folder will be created for your.

如果您的 node_modules 安装在 /home/UserName/ 中，就像在我的情况下一样，您的 package-lock.json 文件也将在那里。只需删除此文件，返回您的应用程序文件夹并运行npm init，然后npm install <pkgname>（例如 express）将为您创建一个新的 node_modules 文件夹。
